cpvc plumbing

[Deere Dude]

I usually find my expert advice on the can label.

But here is an example:

Now I am embarrassed!! I could have swore I checked the label over the years, but not lately, and never saw the times. Thanks for not rubbing my nose in it.

Uhmmm your a guy.... Reading instructions reduces your man credits.

Instructions? We dont need instructions, we're men.

I think I usually wait 10-15 minutes, when I'm making repairs and additions. When I've plumbed my house and addition, it had months of curing time. I don't recall ever having a failure from the solvent weld. I'm pretty sure that the 15 minutes to 2 hours recommended has a huge safety factor - nothing wrong with that.

I do recall that the first time I turned on water after I had plumbed my house (2 stories with a basement) - i had opened valves to let air out - and I was running up and down the stairs shutting off valves and listening for leaks (house was framed with no drywall on yet). After about a minute, everything had settled, I closed the last valve, no noise, no leaks - I was doing great. Then

BOOM - from the basement. I went running down the stairs and a 90 fitting had blown off my 1" incoming PVC line (located before I converted to CPVC). Luckily, I had installed a shut-off valve right where the water supply entered, and I got it closed quickly. Upon examination, I had never put any glue on that joint (should have used purple) and it had probably just held as long as it did from friction until the pressure overcame it.

All in all, not to bad for my first time plumbing a house, but it could turn into a mess in a hurry.

Good luck and take care.

That 2 hour cure time is fairly new. It used to be 24 hours so don't feel bad.

24 hours!!! no wonder you would want copper, who wants to wait a day after a cpvc repair to use the water. i am not sure anyone but new construction kept to that, just like i am sure very few wait two hours, at least people doing a quick repair to get back up and running. 15 mins is easy by the time you get out or put back what your doing 15-30 mins have passed.

Apart from one mention of a 10ft length of cpvc at $5 and copper at $14 for the same, nobody has mentioned actual prices. Looking at UK sites I am not finding any info there either. Does cpvc come in coils as well as lengths? Can someone give a US price comparison for PEX and cpvc please?

Home depot -
1/2 inch 100 feet PEX $28.52, 1/2 inch 5 feet $1.86
1/2 inch 10 feet CVPC $2.70

The thing is that PEX has some costs you may need to factor in. The pipe is cheap, but the fittings not so much, and the tools have a cost. Again, in my book, totally worth the costs as it is still way below copper in my hood.
