  1. If you live in a rural area and have an ongoing battle with the mice, I'm wondering if copper is a safer bet? The dam mice might do a job on the pex plumbing, any thoughts?

  2. Cpvc sucks! After about 10 to 20 years you cant cut it with those cutters! It will crack up instead of cutting through, sure new it looks awesome but no dont use that stuff, please take it from me, im in apartment maintenance, i know you guys all think we just do the handyman fixes but trust me im the odd man out, pex is the best! The only thing bad about it is when using rings to repair you gotta have room to use your tool

  3. IIRC, in MA, by code you can't use CPVC for water in, only for water out. I could be wrong. – A big source of corrosion I see with homeowner copper install is people who use steel/iron pipe hangers to suspend their copper. I even lived (rented) in a place where the basement flooded because the homeowner had connected copper directly to the iron utility coming off the street, without a brass bridging connector. That was a heck of a mess we caught before the pipe failed fully.

  4. If CPVC is not supported properly overtime it will start the stretch and deform I ran into that at my old house. The person that Plum the house didn't have enough straps instead of doing every stud they did every other stud and in some cases every 3 studs so between those straps the pipe was sagging up to I think the worst spot was almost a foot so when I helped a friend remodel his house we strapped on every stud and that was almost 15 years ago and he's had no sag or deformation

  5. I am new to knowing about Pex, but think the fittings bought the other day are different frim both of yours. These just pop on like CPVC (without any glue) and use a very cheap little tool for taking the connection back apart.

    The connections probably cost more though, probably around $2 to $3 each.

  6. Confirming hot-tub failure of cPVC pipe after only 3 years when cPVC pipe is used in the UV-light filter/cleaner. The cPVC pipe weakened/thinned from its inside out, to the point of being able to press thumbnail right through it as if butter. So it seems cPVC either becomes brittle hard (per comments below) or else butter-mush-soft when exposed to constant UV light for 3 years.

  7. Plastics are endocrine disruptors. In cruder words, plastics "faggify" males and "lesbiaze" females. cPVC and PEX are plastic. See youtubes by CURTIS DUNCAN particularly the interview by Radio314. There is a long-term mass depopulation agenda called EUGENICS, a special word of "racial hygeine" (google it). Obama's "science czar" wrote a 1,400 textbook on it (called ECOSCIENCE — google it, read chapter 14), including how to sterilize (and thus depopulate) the witless masses of water-drinkers by poisoning water supplies. Plasticizing water via plastic pipes counts as "poisoning water supplies". W T F U

  8. I very much enjoyed the informative video as a past "owner builder" of a house. Our previous neighbor in Vancouver Canada (we moved aboard a sailboat 5 years ago) has been instructed by his insurance company to have all Pex plumbing removed from their quite new home of approx. 10 years or they will not be covered by insurance. I found this to be quite shocking as the house I built in 2006 was plumbed with Pex to save on labour costs and was recommended by my plumbing contractor….on my future build (when we return to land life), I would probably go back to traditional copper.

  10. Love your videos I was always wondering what if you put a brass threaded system they sell threaded brass fittings and they sell brass pipe so I'm wondering if this would surpass any of these I'm a pipefitter of 25 years and out of the three I would go with CPVC but I've always wondered if you use brass piping how would that be

  11. The Copper Pipes Starting getting small pin Holes throughout my house at approximately the 38-40 year mark. Ontario Canada, city water. Going to replace it with PEX i dont know how long that will last but I will be selling the home in 5 to 10 years so im not to worried.

  12. You didn't mention threaded steel pipe. Stainless, galv or black.
    Requires a lot more work and planning. Biggest advantage is it is drill proof when embedded in masonary, and spade proof when buried.
    Copper joints require brazing, not soft solder as demonstrated in some jurisdictions.
    Coloured xPVC primer makes the inspector's job easy too.
