2017年8月25日 · Ultimately, PEX is the best option these days, but the type of PEX is more dependent on your situation. If you plan to do more plumbing in the future and/or the pipe could be subject to freezing, PEXa along with Milwaukee's expansion tool (Milwaukee #2432) is the way to go for worry-free connections.

2025年2月4日 · If your PEX pipe showed stress fractures and discoloration, it’s possible that high chlorine levels, UV exposure before installation, or pressure fluctuations contributed to its failure. Since PEX can degrade over time, especially with crimped fittings or poor installation practices, a full replacement is the safest long-term fix.

2014年7月28日 · I'm concerned about post manifold pressure. The distance from water supply to manifold is ~15ft over 3/4" pipe. A simple example from the xls i created: Kitchen sink is 63.56ft from the manifold, using a 3/8" pipe. According to the PEX manual (the above images) that is …

2008年7月31日 · The problem, as I see it, is that the inside diameter of the PB pipe is larger than PEX. The outside diameters are the same. So the little plastic insert that is designed to help keep the pipe from shrinking and slipping out is useless. (I remove them when used with copper.) PEX fittings cannot be used with polybutylene.

2023年2月13日 · 3/8 pex outflows 1/2 copper. The statement of pex creating back pressure between valve and open spout is idiotic. I would not use a straight length of pex, which would be about 4-5 feet or less, between the valve and tub spouts because of thermal expansion. Something like 1" per 100' per 10°, that's why you run expansion loops for runs of pex.

2020年9月27日 · The PEX Splice appears to be a plastic fitting with copper crimp rings. Pureflow PEX Writing. Note: I noticed that as I was cleaning the pipe, the writing was coming off the PEX Pipe. The dirt was acting as sandpaper. So I have be very careful as I was cleaning the dirt away from the PEX so that I could get a good picture of the writing on the PEX.

2015年1月9日 · I was thinking of pulling a string down through the wall when I remove the old pipe then attaching the strings somehow to the PEX to help guide it through the previously drilled holes. I was wondering if there is some kind of bullet shaped device i could thread into the end of the pex with a string attached to it to pull the pex up through the ...

2012年4月26日 · Pex pipe has three recognized manufacturing methods, and -A has been around the longest, and is still probably the best way to do it, but it costs more. For that cost, you get a pipe that can be bent into a smaller radius than the others and one that can be restored if you do, for chance, kink it without requiring you to cut the kink out and ...

2024年12月8日 · 2. You can use compression rings and stainless steel clamps on fittings made for PEX B or C. The pipe is the same size. The fittings are different from F1960 expansion fittings, so if you use copper rings, get the usually-cheaper fittings. I have never seen a drill attachment tool for pex. Got a link? Hand tools work well if you have clearance.

2012年4月17日 · if you want it to be rock solid like traditional copper terminate the pex with an drop eared elbow fastened to an backer board and stub out with an nipple and an threaded angle stop.just be sure to use some teflon tape and some good pipe dope.two brands that are good are hercules blue block or loctite
