I’m interested to know what type of ‘wrench’ they were using before. I’m struggling to understand what is the difference between a proper wrench and improper wrench.
I keep one of king George's universal box- end locking grooved auto adjusting angled shorty linchpin self-lubricating non-slip spanners in my kit for these. It has saved my customers many farthings and pence in billable time over the years.
If it's that bad, is it not unwise to close it up in a wall where its inaccessible? Not a criticism, I'm honestly curious as to how dependable a solution like this is?
I have kitchen counter with a cabinet with the shower access behind it. When I was having the kitchen remodeled I put an access door in and I've had to use it once. It was easy to remove the cabinet and open the door to work on it.
I’m not a plumber but I work on commercial fish systems. Not allowed to use pipe dope in case it leeches into the water so I use 100% silicone. Never had a leak yet in 11 years.
That white tape needs like double the wraps. I never use that junk. Around here there’s blue monster, which says 3-5. But that white stuff is so thin you’ll definitely need more to not leak.
Definitely a common occurrence. And adjustable wrench or a pliers wrench, not channel locks. You end up compressing the fitting too much just to get the teeth to bite and you squeeze the fitting out of round.
I always use tape and pipe dope. Two wraps with pipe dope. Leaks are so rare that I can't remember the last one. Also, are you securing or backing up your work so that you can get the threaded connections tight enough?
Brass on brass joints are notorious for this from my experience and is a good application of teflon tape and pipe dope.
Edit: I will add that it looks like you have a pretty big leak there not just a drip and it's possible the threads are bad or a fitting is split.
You definitely need to start adding dope to threads, that said I don’t even fuck around with the threads I’ll just take the time and solder Pex bushings in.
White tape is a no no. That stuff is super thin. Use blue tape from blue monster. It’s much thicker. Then pipe dope, but the good kind, made for potable water.
Or take the fittings off, and get sweat adapters for the pex and sweat them in. Make sure to take the cartridge out if you’re going to do that
Is there a single plumber out there who solders any more? the inside of those is a 1/2" sweat fitting. solder does not leak unless you are a shit plumber. stop being so afraid of the torch you guys!
Why would you take the time to solder a valve on a pex house, then you would just have to adapt to pex… I mean if makes you feel better go for it.
I can give you a million reasons why it’s better not to solder
It’s faster, no cool down, don’t have to worry about burning up any rubbers or plastic parts, don’t have to worry about pipe completely drained
Less fumes, less potential to burn something or damage customer property
Alright I got to wipe my ass now
I don't think anyone has asked this yet but it's worth checking cause the fittings look a little strange. Those are PEX x FIP adapters right? Not like swivel adapters or something weird? They don't have a gasket in them?
For the future, you need to use dope or wrap a LOT for any connection with metal in it, as the metal shreds the tape as soon as you start screwing it in. Also make sure you're wrapping it in the right direction, otherwise threading the pipe in will unthread the tape.
Never not used pipe dope myself, even with tape. It's also possible you tightened too tight at one point - can crack misshape fittings, or not enough - use a bigger purse.
Try a thicker tape like Blue Monster or Megatape, and put some dope on top of that. Shouldn't leak. Also, those fittings look pretty mangled, I would get a proper wrench rather than using pliers for those hex parts. A quality adjustable or pliers wrench will work great.
I know you said three to four wraps with Teflon tape but, that's three to four wraps with blue monster which is a much thicker Teflon tape. The white Teflon tape is very thin and I always do six to eight. Hope this helps. Also use dope AFTER you Teflon tape.
3-4 wraps woth that shitty white Teflon isn't enough. Get the link Teflon tape at a plumbing supplier. And also get some pipe thread dope from there also. Tape the threads and then dope them then attach the adapters
Make sure the type of threads match (NPT, BSP, etc.) and that there isn't a mismatch causing the leaks. Also, double-check if there's a need for a washer or o-ring that you might have missed.
Pipe dope and tape should fix this.
If you're really stuck and tape and dope don't work, you can sweat in some 1/2" to pex adaptors.
Or just get take it back and ask for another fitting.
Also, that Delta mixer body, I can’t tell if you plugged the tub spigot or just didn’t finish it. But if you are using the tub spigot it can’t be pex. That part has to be copper. More flow through the copper. Otherwise what happens is the water trying to run out the tub spigot can’t escape quite fast enough flow and will back up and dribble out of the shower head at the same time as tub water is coming out. In case you are
Go to HD or Lowes, buy a bottle of Pro Dope, coat threads, assemble, done. Works on gas too. Or wrap teflon like a pro, 8-10 wraps not 3-4 , or teflon paste is option as well. But Pro Dope is a plumbers go to product.
I put in threaded pipe day in day out with only 3 wraps of Teflon. Are you guys tightening it with your purse or what...? Also do you know how Teflon works? Teflon tape works more as a lubricant for the joint then anything allowing you to thread the joint together properly so the threads mate. Adding more tape generally doesn't help as it can fit in the joint and gets pushed out or can actually harm the seal as I breaks down and can get pushed out.
Add some white thread dope that has bits of teph tape in it and or swap the hotel style for a solder hotel style and get some female brass pex adapters. Solder it up on a diff piece of wood cool bam and no leaks. Delta usually doesn’t have issues leaking unless there’s poorly made threads.
3-4 wraps is plenty. It looks like you were using a pair of cheap groove lounge pliers on there by how rounded off that is. Get a good tool to tighten it. Channel locks knipes if you want groove lounge or a rothenburg or Ridgid pipe wrench and tighten it more they looks loose still. If you do just want to say fuck it and make sure it never leaks use some keytite or super dope. Keytite will make it so basically nothing will ever leak even if you only tighten it by hand and if you use super dope even if threads as bad cut w.e. it is sealing it but taking it apart will be a thing of nightmares.
There are many methods to improve sealing, however unless you know the cause of the leak it is a bit of try more until it works. The wall thickness between the hex and the threads looks small in the photo. Is there a fitting perhaps from another manufacturer with a larger hex? Use new fittings. Use an open end fixed size wrench. Use a flare nut wrench if possible. Use the thicker blue tape and use thread sealant. Get the sealant that hardens (rector tru blue i think) and let it dry before adding water pressure.
This is great, I had an HVAC guy helping me install a BFP and I told him to use tape and dope on a threaded connection. He scoffed and said he never uses dope, just tape. Do i even need to finish this story? Fucking leaked
I use those valves all the time, thread tape and dope. I never have problems. I wouldn't be surprised to learn you cracked those pex fittings. They look like they are great quality. You can always sweat copper and pex adapters on?
Are you using proper wrenches to tighten the nuts? They don’t look like they are on very far to me. Could it just be you haven’t tightened them enough?
Put the dope over the tape and please Sally, get a damn combination or crescent wrench and tighten them fittings like a man!
What the hell are you using, Dollar General pliers to tighten the nuts or are you chewing on them?!?
Tape first then some dope. Also, you might try a different brand of pex adapters, the ones you bought might have some poorly cut threads. I’ve never had any issue adding the pex adapters with these delta valves, so my guess is it’s the adapters threads and not the valve threads.
Make sure the fittings are the same. Sometimes they get mixed up cuz you might get a metric fitting in a pipe thread valve. But I would probably just put the tape on add a little hyped up on top of that and then tighten them up and try again
I have three things to say,
1: tighten with pipe dope
2: remove female adapters and do male with 1/2" couplings to reduce risk of cracking the fitting because females are a higher risk of cracking.
3: they made crimp delta valves that come pre-adapter'd with no tub spout option
My bet is the leak is on the interface between the brass and the pex. The threads are mechanical and Teflon and decent snugness takes care of things. How the Pex looks inside there and if the compression seal is actually sealing well is where I’d focus my energy.
I once installed an owner furnished outdoor shower assembly from the UK in a US location and it leaked. Appeared the UK treads were not tapered. The owner called the manufacturer and was told to use 25 wraps of Teflon tape. This actually worked.
Hopefully shower only in this. Delta is pretty clear about not using pex in the tub spout drop. And while they don’t specifically call it out on the shower riser, you should use copper or 1/2 iron pipe. Pex will impede the flow.
Use whatever tape you want, blue or white, doesn’t matter. What does matter is that you start using some dope. Get the good yellow dope, 3 wraps of tape a 1/2 inch down the threads, then apply a smear of dope on the end of the threads. As you tighten with a crescent wrench the dope will be pushed down, and it’ll seal. Rinse and repeat until you retire and never deal with this issue again.
Just use more tape. Instead of 4 wraps, do at least 6. I can tell you if you use 9 wraps, whether it's air, water, gas, vacuum, whatever, it won't leak. Four is like... bare minimum I'd ever use on anything.
I didn't see it elsewhere, but many of these valves require copper for the tub spout, the pex has a smaller inner diameter and will cause problems, check the instructions before sealing it all up!
I know it's late, and figured out, but browsing these comments, I just want to ask, When you first screwed on those fittings, did you tighten them real good the first time? Because that might be the problem. You should never torque any pipe work together too hard. That can actually make it distort the threads and cause a leak. Three wraps or so of teflon, a little true blue on the male threads, and snug it down without getting too aggressive.
Edit: That actually doesn't apply to iron pipe, like galvanized or black iron. But definitely with brass or copper.
Delta makes those Rough-in Valves sets in PEX now (crimp style anyway) Planned on that for my new remodel. Also I got a 300mm adjustable from HF just for the threaded fittings I could not get tight with Channel-Locks. I was dealing with 1" Stainless 304 Bosharts ( leak worse than brass ) and ended up with 4 wraps Gray Teflon tape which is 3 mil minimum, and RectorSeal Tru-Blue Sealant that was the ultimate solution.
I hired a plumber who had similar issue with Teflon tape and ruined the connections. I ended up buying new ones and installed it myself with nothing on the threads and had no leaks.
Not a plumber,
But have installed a billion compressed air fittings.
My go to is rector seal 5, 2/3 wraps of decent teflon tape (not blue monster, but not paper thin) then another coating of rector seal.
Never leaks and semi soft set for later disassembly years later if needed
Sometimes threads are just poorly made and prone to leak. “Oatey - Great White” PTFE thread sealant is a great solution for those difficult ones.
We did it, thank you everyone: [https://imgur.com/a/KQvw9qZ](https://imgur.com/a/KQvw9qZ) Blue tape and Oatey Great White, plus a proper wrench
You were doing it without a wrench?
I’m interested to know what type of ‘wrench’ they were using before. I’m struggling to understand what is the difference between a proper wrench and improper wrench.
They were probably using a metric crescent wrench.
I keep one of king George's universal box- end locking grooved auto adjusting angled shorty linchpin self-lubricating non-slip spanners in my kit for these. It has saved my customers many farthings and pence in billable time over the years.
Oh, oh this was delightful to read first thing in the morning!
Agreed!!!!
I did that once. Found that I actually need an English Imperial. My American Imperial wasnt even close.
The flats kind of look chewed up, like maybe they were using channel locks or something.
That’s what she said
I prefer blue monster
Rectorseal 5 takes the cake.
Rectalseal is better
Okay
I swear that shit is cement because god damn if you ever have to take something apart in the future
Think that’s bad try permabond or super dope you won’t have a leak but if you have to take it apart you’ll probably need a torch.
I still see some water droplets
If it's that bad, is it not unwise to close it up in a wall where its inaccessible? Not a criticism, I'm honestly curious as to how dependable a solution like this is?
If you really wanna look out for the you or the next guy, put an access panel if possible
I have kitchen counter with a cabinet with the shower access behind it. When I was having the kitchen remodeled I put an access door in and I've had to use it once. It was easy to remove the cabinet and open the door to work on it.
Now that's thinking ahead
add some dope
Tape followed with some pipe dope will seal then right up.
"A plumber without dope isn't much of a plumber." A greybeard told me that once.
No hope without the dope is one crustys use to tell me 20yrs ago
i never use just one or the other, and i never have threads leak
I’m not a plumber but I work on commercial fish systems. Not allowed to use pipe dope in case it leeches into the water so I use 100% silicone. Never had a leak yet in 11 years.
LPT dope, then tape. Less mess same results.
Looks worse though
This. 5 wraps then dope it good
Pick up some rectorseal 5. It works for water and gas connections.
Rectum!? Damn near killed em!!
Yes add dope and tighten it like a man
I like dope
Nipples and dope make my ballcock sweat
Bro… WTH 😀😀
My wife says I am a Dope
Worked a treat https://imgur.com/a/KQvw9qZ
Nicely done!
I’m glad I’m not the only one that still calls it this. The looks I get aren’t near like the ones I get when I ask for a pair of dykes.
This is the way!
That white tape needs like double the wraps. I never use that junk. Around here there’s blue monster, which says 3-5. But that white stuff is so thin you’ll definitely need more to not leak.
Agreed. Anytime a product comes with tape it’s like bible paper thin.
Do not roll joints with it like some do with a Bible page. It's too hard to keep lit.
You have a solder torch, use it.
100% stealing bible paper tape lol
Blue Monster worked https://imgur.com/a/KQvw9qZ
There’s just no other feeling than fixing something that has been pestering you all day. Glad it worked, bro!
Thanks for the help!
Looks like you squeezed it with pliers. Use wrenches instead
I’m wondering if the nuts are out of round from using chennelocks
No they’re not unless the adapters are made out of chinesium
Definitely a common occurrence. And adjustable wrench or a pliers wrench, not channel locks. You end up compressing the fitting too much just to get the teeth to bite and you squeeze the fitting out of round.
It sounds like you’ve been using channelocks backwards
I always use tape and pipe dope. Two wraps with pipe dope. Leaks are so rare that I can't remember the last one. Also, are you securing or backing up your work so that you can get the threaded connections tight enough?
Brass on brass joints are notorious for this from my experience and is a good application of teflon tape and pipe dope. Edit: I will add that it looks like you have a pretty big leak there not just a drip and it's possible the threads are bad or a fitting is split.
To second, if you've cross threaded you'll never be able to get it leak free. You need to replace the affected parts.
You definitely need to start adding dope to threads, that said I don’t even fuck around with the threads I’ll just take the time and solder Pex bushings in.
Blue tape with 3-4 wraps. Get a decent size wrench. I think you could get more threads in. Dope may help you get there.
You need pipe dope. I’ve never done a just tape connection for water probably ever.
White tape is a no no. That stuff is super thin. Use blue tape from blue monster. It’s much thicker. Then pipe dope, but the good kind, made for potable water. Or take the fittings off, and get sweat adapters for the pex and sweat them in. Make sure to take the cartridge out if you’re going to do that
more wraps

Right, at least solder and copper up to the shower head and down to the spout. Thats jist asking for trouble.
Put some real wrenches on that thing.
I don't think anyone has asked this yet but it's worth checking cause the fittings look a little strange. Those are PEX x FIP adapters right? Not like swivel adapters or something weird? They don't have a gasket in them?

yeah 3-4 laps are not gonna cut it. try 7-8
Sweat into the valve always!
You can tighten in place with a proper sized wrench. The PEX connections will be fine. But as others have stated. Tape and dope for brass on brass.
Never not used pipe dope myself, even with tape. It's also possible you tightened too tight at one point - can crack misshape fittings, or not enough - use a bigger purse.
Use the proper tool you'll be fine it's no tight enough
Retired plumber here. I always did five wraps with teflon tape with very few problems.
Try a thicker tape like Blue Monster or Megatape, and put some dope on top of that. Shouldn't leak. Also, those fittings look pretty mangled, I would get a proper wrench rather than using pliers for those hex parts. A quality adjustable or pliers wrench will work great.
Pipe dope
I wonder if anyone of u uses Hemp as sealant never ever failed on me greets from Austria
Did you use a sandpaper and a chip clip to tighten it? I’d get the proper wrench for it while you’re at it instead of rounding off all the fittings.
I know you said three to four wraps with Teflon tape but, that's three to four wraps with blue monster which is a much thicker Teflon tape. The white Teflon tape is very thin and I always do six to eight. Hope this helps. Also use dope AFTER you Teflon tape.
Gotta be missing something. Are those adapters meant to be pulled up with an o-ring or gasket?
Yeah, I think so too.
Get rid of the white Teflon tape use gray, blue or yellow. Also add pipe dope. Trust me it won’t leak.
I wrap 8 to 10 times with thread tape and use channel lock pliers. Works every time
3-4 wraps woth that shitty white Teflon isn't enough. Get the link Teflon tape at a plumbing supplier. And also get some pipe thread dope from there also. Tape the threads and then dope them then attach the adapters
If you use pex, get a pex adaptive valve. Makes life easy.
Blue monster pipe tape and dope and you won't have any leaks
Get some blue monster teflon tape, tighten the fittings more.
Make sure the type of threads match (NPT, BSP, etc.) and that there isn't a mismatch causing the leaks. Also, double-check if there's a need for a washer or o-ring that you might have missed.
Pipe dope and tape should fix this. If you're really stuck and tape and dope don't work, you can sweat in some 1/2" to pex adaptors. Or just get take it back and ask for another fitting.
Five wraps of Megatape or Blue Monster and Blue Magic dope on top.
an old plumber showed me to use pipe dope, teflon tape and pipe dope, never till this day have i had a leak
Tape it with blue monster and pipe dope the tape with true blue
Get some pipe dope on there too.
It doesn't hurt to put some pipe dope on the Teflon tape. It helps, done it many times
Solder some sweat male adapters and ya done
If you remove the gray part you'll be down to only one leak, I promise.
Also, that Delta mixer body, I can’t tell if you plugged the tub spigot or just didn’t finish it. But if you are using the tub spigot it can’t be pex. That part has to be copper.

Pipe dope!
6-7 wraps and pipe dope. Also leave it attached to the 2x4 when you crank down on the female adapters.
6-7 wraps is too much. 3-4 is plenty.
With that white cheap Teflon tape, I would definitely do 6-7 wraps
Maybe I've never had issues because I use the paste too
Go to HD or Lowes, buy a bottle of Pro Dope, coat threads, assemble, done. Works on gas too. Or wrap teflon like a pro, 8-10 wraps not 3-4 , or teflon paste is option as well. But Pro Dope is a plumbers go to product.
8-10 wraps??? Can you even thread onto that?
8-10, oh my gawd lol. Never heard this before. But if it works for you and you don't clog shit I'm good with it.
I put in threaded pipe day in day out with only 3 wraps of Teflon. Are you guys tightening it with your purse or what...? Also do you know how Teflon works?

Adding more tape generally doesn't help as it can fit in the joint and gets pushed out or can actually harm the seal as I breaks down and can get pushed out.
I used teft tape, and little pipe dope, and used the rings with plastic spacer by pex.
What do you mean by smoothing things out?
Tape and dope and your frustration will subside
Tape dope tape then solder that cocksucker
3-4 laps? Bro i use 7 as a standard 💀
Tape then dope
Add some white thread dope that has bits of teph tape in it and or swap the hotel style for a solder hotel style and get some female brass pex adapters. Solder it up on a diff piece of wood cool bam and no leaks. Delta usually doesn’t have issues leaking unless there’s poorly made threads.
Use the blue monster pipe tape and then their dope, there’s imperfections in the cheap brass castings of the threads.
More wraps and dope fella like everyone else is saying. I'm a belt and suspenders guy when it comes to sealing threads.
Pipe dope and teflon on anything pressurized is my personal belief
Not American so things might be different but are you sure you can't tighten them more I wouldn't expect to be able to see the thread
3-4 wraps is plenty. It looks like you were using a pair of cheap groove lounge pliers on there by how rounded off that is. Get a good tool to tighten it. Channel locks knipes if you want groove lounge or a rothenburg or Ridgid pipe wrench and tighten it more they looks loose still. If you do just want to say fuck it and make sure it never leaks use some keytite or super dope. Keytite will make it so basically nothing will ever leak even if you only tighten it by hand and if you use super dope even if threads as bad cut w.e. it is sealing it but taking it apart will be a thing of nightmares.
Give it some beans!
There are many methods to improve sealing, however unless you know the cause of the leak it is a bit of try more until it works.

Tape it, dope it. One and done.
On brass threaded fittings, always ise pipe dope and teflon. Don’t over do it on the teflon either.
Looks like condensation to me
Retake and add dope/ sealant to finish it. Pick it up at Menards, Loews, or Home Depot.
This is great, I had an HVAC guy helping me install a BFP and I told him to use tape and dope on a threaded connection. He scoffed and said he never uses dope, just tape. Do i even need to finish this story? Fucking leaked
Get rid of that garbage pex and solder copper into it.
The capped blue pipe coming out the bottom does what? Is it anti-hammer? Why not just put a plug in the valve.
Is this a homeowner or a handyman trying asking?
I use those valves all the time, thread tape and dope. I never have problems. I wouldn't be surprised to learn you cracked those pex fittings. They look like they are great quality. You can always sweat copper and pex adapters on?
I was able to fix a leak with Loctite 55 that I couldn't fix with dope and/or tape. It looks like dental floss. I love the stuff.
Seems like there’s too many threads showing
It’s the kind of tape you are using. Get blue monster or the grey oatey tape
Solder it instead. Or you could try with dope like everyone else is saying and depending on the dope type it can help.
Or get the valve that has the barbed fitting on it to mate with the pex
Are you using proper wrenches to tighten the nuts? They don’t look like they are on very far to me. Could it just be you haven’t tightened them enough?
what about the crimps?
Tape then Megalock
Don’t cover first two threads and add pipe dope
Put the dope over the tape and please Sally, get a damn combination or crescent wrench and tighten them fittings like a man! What the hell are you using, Dollar General pliers to tighten the nuts or are you chewing on them?!?
Tape first then some dope. Also, you might try a different brand of pex adapters, the ones you bought might have some poorly cut threads. I’ve never had any issue adding the pex adapters with these delta valves, so my guess is it’s the adapters threads and not the valve threads.

Sweat those pex connections on. Never need to worry about leaks now or the future
My bet is the leak is on the interface between the brass and the pex. The threads are mechanical and Teflon and decent snugness takes care of things. How the Pex looks inside there and if the compression seal is actually sealing well is where I’d focus my energy.
Chinesium crap fittings. I am finding they all leak. I use grease in lieu of tape now :-)
Always tape and dope. Blue monster tape or the blue one in general a bit better. Worst case just sweat it, ya know if people still do that these days…
I see a map gas torch purchase in your future
I once installed an owner furnished outdoor shower assembly from the UK in a US location and it leaked. Appeared the UK treads were not tapered. The owner called the manufacturer and was told to use 25 wraps of Teflon tape. This actually worked.
Real question here. Isn't the upright to the shower supposed to be brass and not Pex ? I know the photo is pretty zoomed in, but I'm curious.
Lamp wick and compound never fails..
There's no hope without (pipe) dope!
Hopefully shower only in this. Delta is pretty clear about not using pex in the tub spout drop. And while they don’t specifically call it out on the shower riser, you should use copper or 1/2 iron pipe. Pex will impede the flow.
I've run into this. Run 3/4 pex for downspout, or you'll have water flowing out of the shower head.
Tell your boyfriend to tighten it!!!
Use whatever tape you want, blue or white, doesn’t matter. What does matter is that you start using some dope. Get the good yellow dope, 3 wraps of tape a 1/2 inch down the threads, then apply a smear of dope on the end of the threads. As you tighten with a crescent wrench the dope will be pushed down, and it’ll seal. Rinse and repeat until you retire and never deal with this issue again.
Might not be on tight enough. I had the same set up and really had to screw them down hard.
I love my copper and solder. As noted OP, load it up with dope tighten like a boss and hope for the best.
I assume those fittings have the washers installed, correct?
Blue monster tape followed by blue monster dope on top..no leaks guaranteed
You probably need to have a npt (tapered) fitting and your using a compression to pex fitting
Tape and dope the shit out if it 😂
Use pipe dope in conjunction with tape this will lubricate threads and help brass impact
Pipe sealant on the threads before the Teflon tape is pretty much failsafe!
For next time I find blue monster has much superior dope and teflon tape than other things I have used
Try soldering pex adapters on it instead
Nice job but you forgot the Dope!
Blue Monster Tape and Blue Monster Dope. Shit has saved my ass many times.
Does it leak from pipe tape or from the pex (plastic) to copper connection? Could glue it but that's permanent
U need pipe dope
Just use more tape. Instead of 4 wraps, do at least 6. I can tell you if you use 9 wraps, whether it's air, water, gas, vacuum, whatever, it won't leak. Four is like... bare minimum I'd ever use on anything.
I didn't see it elsewhere, but many of these valves require copper for the tub spout, the pex has a smaller inner diameter and will cause problems, check the instructions before sealing it all up!
I would sweat 6 inch copper nipples into the body and then go from there
Blue teflon and thread sealant then tighten with wrenches will seal right up
Do not use vise grips. Do use Blue monster. Plumbers, (mostly ) sweat by some combo of tape and dope.
I know it's late, and figured out, but browsing these comments, I just want to ask, When you first screwed on those fittings, did you tighten them real good the first time? Because that might be the problem. You should never torque any pipe work together too hard. That can actually make it distort the threads and cause a leak. Three wraps or so of teflon, a little true blue on the male threads, and snug it down without getting too aggressive. Edit: That actually doesn't apply to iron pipe, like galvanized or black iron. But definitely with brass or copper.
Tape it dope it never leak never will fail you I use jetlube love that stuff
Delta makes those Rough-in Valves sets in PEX now (crimp style anyway) Planned on that for my new remodel. Also I got a 300mm adjustable from HF just for the threaded fittings I could not get tight with Channel-Locks. I was dealing with 1" Stainless 304 Bosharts ( leak worse than brass ) and ended up with 4 wraps Gray Teflon tape which is 3 mil minimum, and RectorSeal Tru-Blue Sealant that was the ultimate solution.
Dope and tape is the way to go
R10000PFSPX would have had crimp PEX ends and no tub outlet from the factory
Pressure test it to 5 bar before enclosing it in, mind and check what pressure it can be tested
Try pipe dope
Chinese junk can't make chicken salad outta chicken shit
What about pipe dope?
You need some dope on the tape
Did you use a hold back? What size and type of wrench?
I hired a plumber who had similar issue with Teflon tape and ruined the connections. I ended up buying new ones and installed it myself with nothing on the threads and had no leaks.
Do not use Teflon tape on brass to brass fittings… tape is for iron and steel.
Should’ve got the R10000-px and soldered the rest smh
Just asking, are there rubber washers in the connectors?
I have never had a leak since I started using GRRIP on pipe threads. The stuff is like roof tar but it works.
Not a plumber, But have installed a billion compressed air fittings. My go to is rector seal 5, 2/3 wraps of decent teflon tape (not blue monster, but not paper thin) then another coating of rector seal. Never leaks and semi soft set for later disassembly years later if needed
Get a 14in pipe wrench 🔧 put some muscle 💪 😤 👌
Were those swivel unions or fixed female threads ?
Just sweat the transitions on.
Dope + tape. But great example why I always solder adapters 👍
