i had a tight space for putting in a shower valve, used pex quick
connects 2 to 4 bucks pricey but worth it no way to get a torch in
there , the reaming tool is exspensive but my dad already had one,
ummm.. can i borrow that
Thats cool.My brother and I ran some1/2 in PVC through a PVC sewer
pipe like that several years back. The galvanized plumbing under the
slab in my dad's house had gone bad so we had to run it through the
attic. Even though we only needed about 15 ft to go from kitchen to
bathroom we extended the sewer pipe the length of the house. The idea
was that should it freeze the water would be allowed to drain outside.
Wish they had PEX back then.
Dunno about PEX and sun but PVC and sun seem to be okay. I have a
"temporary" PVC line from one hydrant to another that is inoperable -
about 65' total that has been in for .... well, years. The only
repairs I have had to do is replace a few spots that broke from
freezing when I forgot to drain it in time...hmmm....seems I did it
again last fall. Wonder how much will need replacing this time.
Don't know if this will be readable - it was extracted from a pdf.
Can Zurn PEX be stored and/or installed outdoors?
No. All plastic pipes can break down when exposed to ultraviolet rays
(sunlight) unless they contain certain pigments or stabilizers intended to
prevent the damage. Exposure of unstabilized pipe to ultraviolet rays (UV)
causes the molecular structure to break down and oxidize causing the pipe
to become brittle and eventually rupture. Zurn PEX contains UV stabilizers
that are intended to protect it for 6 months of exposure, which is intended
for protection on the job site in case the project is delayed. Most other PEX
tubing has only 30-60 day protection. If it must be installed outside it must
be sheathed in a protective sleeve. Zurn PEX should not be stored outdoors.
Yeah to the 'brittle' That is what is happening to my 'temporary'
line. When it does freeze it isn't just a small spot but a long crack
now. Used to be just cut out a foot or so, now it is up to 10 ft at a
shot. Still serviceable and I still have a lot of used pipe in the
shed for repairs. Had it running all over back around 30 years ago to
water new tree seedlings.
That would depend on the reason for the breakage. CPVC pipe is reliable as
long as it's not twisted, pushed or pulled to ther e is a constant stress on
it. If it broke due to freezing, copper won't be much of an improvement over
the plastic properly installed.
What was the faiure mechanism, and what is known about causing it?
Newsgroups are great places to get assistance.
My first suspicion was that when the valve was screwed onto the end of the
pipe, it twisted/stressed/cracked the pipe inside of the wall. A book fell
off of the toilet and hit the pipe and finished the job. That shouldn't
have broken the pipe, but it did.
The end result is that it broke, and wouldn't have if it were copper and
I'm still in a I-hate-plastic-replace-it-all-with-copper mood right now :-)
Have you looked into PEX? If not, you should. If you're planning on
replacing piping, PEX should be seriously considered. It's more
robust that CPVC in many ways, the cost and installation time are both
much better than with copper or CPVC, it handles the occasional
freeze a lot better than either alternative, etc. Couple that, pun
intended!, with some Sharkbite fittings (not cheap, but quick and
secure), or a crimping tool if you're doing a lot.
