Browse Forums Building Standards; Getting It Right! 1 Jun 16, 2020 6:38 pm I'm owner-building a house and a plumber came in today to run the PEX pipe, install mixers, do all the connections etc. He will come again tomorrow to finish the house, so it should be ready for plastering then. I have some concerns and have noone to ask. 1. Is this kind of bend/angle as per first two photos allowable? Doesn't it make the joint under stress and more likely to develop a leak later? Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ 2. Shouldn't the pipe be visible through the small round holes in copper? How critical is it that in many (most) cases the pipe doesn't reach fully or at all the end of fitting? Would love to hear opinions of licensed plumbers as well if they read this!

I am pretty sure you are meant to be able to see the PEX pipe in the witness holes just to make sure the crimp has enough material to grab on. Normally the plumber will put the water on so it's all pressure tested, but just have a chat and explain your concerns. .

My main concern is what if the pressure test will not show any fault at this stage, but what if due to incorrect connection it will develop leak later, when everything plastered / cement sheeted / and tiled and there is no way to get behind the wall and fix it? Don't really want to express my concern to the plumber without any ground. He will not fix anything anyway and probably just say "Nah, she'll be fine, I've been doing so XX years"... Unless this installation is not per code, then I can start demanding Just want to understand if it's a big issue or I'm overthinking it? Would you personally accept this job? (Assuming it passes pressure test)? Re: Plumbing PEX question - urgent advice needed please 5Jun 16, 2020 9:08 pm alexp79 not a big fan of t-junctions in plumbing as they are responsible for the majority of plumbing leaks, but yours look okay in the first iteration. SaveH2O what would you say? Thank you Alex, What about my concerns that pipe doesn't reach the inspection hole in copper fitting? Is that a concern at all? Re: Plumbing PEX question - urgent advice needed please 6Jun 16, 2020 9:13 pm my understanding is same as chippy's - as long as you can see pipe in the witness opening, you are good. I can see a piece of red pipe on the first photo, but not sure is it is clearly visible on your other photos. but ideally I would be certainly making sure that piping is fully past the witness whole Re: Plumbing PEX question - urgent advice needed please 7Jun 16, 2020 9:50 pm alexp79 I can see a piece of red pipe on the first photo, but not sure is it is clearly visible on your other photos. It's not visible at all in other photos. Pipe doesn't reach the opening by 1-2mm probably. Obviously it's not ideal at all, just trying to understand how critical it is and if we have any ground demanding a "fix", which is a lot of work (half of the house has already been done), so that won't go without a fight I'm afraid. On the other hand, maybe it's all ok and I'm overreacting/overthinking the problem, where it doesn't exist.. Re: Plumbing PEX question - urgent advice needed please 8Jun 16, 2020 10:59 pm Like I said before I'm not a plumber so I'm happy to be corrected. The fitting has a very long barbed tail that catches the pipe. Ideally you want to see the pipe completely in the viewing hole but as the pipe can be seen I'm pretty sure you will be ok. If the viewing hole wasn't there the pipe may only be in the fitting a few mm and will obviously fail. If you can see it through that viewing window (even if it's not fully home) there's still a good long length of barbed tail for the crimp to be compressed against. I'm sure the pipes have plenty of redundancy built in. I'd say as long as the pipe extends past the actual crimped section that looks about 5mm from the hole you are not going to have problems.

No 99.99999999% of the time these crimps will be fine for the entire service life of the installation...... BUT! Check the manufactures installation for that brand of PEX. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ I was a plumber and now a hydraulic services designer, and have been involved in a couple of fights with PEX manufactures over defects, and would not leave anything to chance that could give them a way to back out of a warranty because they will. If i saw these joints on my home i would be getting them redone properly. All manufacturers of crimp style PEX fittings would specify similar to above that the witness hole should be completely filled. If there is any issue with a part of the installation the manufacturer will take one look at those fittings and have a way out of any claim made. Since it was not installed to the requirements. The other thing to check which is probably to late now, is to make sure that all the fittings and all the pipework are from the same manufacturer. Plenty of guys mixing fittings and pipework from different manufacturers, and often with stuff out of shipping containers from china at 50% the price tag as from trade stores, which is another issue all together.....
