PEX & Kinks

[5030]

Make sure they extend the spliced in PEX well beyond the kinked section.

I would want the whole section replaced so that there are no extra joints.

That depends on where it's located at. If it's in floor in concrete, no way or if it's in a non accessible wall, same deal.. I was very careful when I ran my O barrier pex not to radius any tighter than the minimum radius listed on the packing list instructions that came with the coils. Kinking any PEX will weaken the structural integrity appreciably.

That depends on what kind of joint they use. Not fond of Sharkbite fittings at all. I prefer brass with nuts and internal tapered compression rings myself. Theyare a bit more expensive however,

I had a piece of damaged polyB replaced due to being damaged during installation in a new house I built in 1996. Somebody got a torch too close to it and the plumber admitted it could only be one of his crew. He wasn't happy about it but didn't argue with me and understood why I wanted the whole piece replaced. It was before the concrete got poured for the hydronic heat in the floor.

I assume they would continue using expansion fittings like they used in the picture. Those are reliable fittings. The 2 problems I’ve encountered with those is not waiting long enough to pressurize the system in cold weather and the fittings getting damaged before installation. The expansion bands will shrink back down almost instantly in warm temperatures but it takes a while in the cold. The fittings are also not very tolerant to damage around the sealing ring. I’ve actually had more problems with brass ones vs plastic ones. The brass ones usually come with a plastic protection sleeve but if it goes missing a tiny dent on the sealing ring will make a leak. But both of those problems appear instantly not in the future.

The ones I got (no need anymore) had a plastic (nylon tapered washer that fit over the brass ring and compressed it with a threaded brass nut. Never had a leak issue and I have a lot hook ups too. I tried the sharkbite fitting with no luck at all.

I used sharkbite fittings years back, no issues. Previous owners did an addition, sharkbite fittings were used on baseboard heat, no issues...

Maybe I got some Chinese ones then. Big leakage problems here and Cryotek isn't a cheap date either and I'm filled with it, 59 gallons to be exact. One gallon left over which is long gone, used it im my spray rig years ago instead of RV antifreeze.

The vast majority of sharkbite fitting failures are user errors. You have to cut the pipe straight and clean and install it so it doesn’t put the fitting in a bind.
