I have a buried water line with is 3/4 blue pipe, probably
polybutylene, that was put in 30 years ago that I need
to connect to 3/4 CPVC line.
Ive heard that regular CPVC couplings and cement are
not a good way to do it.
Does anyone have any suggestions on how to make
the connection properly ?
I had that stuff in my boat and it was discontinued
due to problems. Here's the bad news:
And the good news if you decide to co-exist with it:
Looks like Sharkbite that are available at HD
might be approprate too.
The problem is that now that it's old and getting
more brittle, it's probably going to be like working
with nitro. Like after you tighten up a new fitting
how do you know the pipe isn't now going to fail
a month later because it can't handle the extra
stress? On my boat I only had 50 gallons of
water to worry about and two bilge pumps :)
As Clint Eastwood would say, "So, how lucky
do you feel?"
Yes. I looked up the website and saw the connector and it
looks like it will do the job.
Do you or trader4 have an opinion on whether the Sharkbite
works better than a crimped Poly/CPVC connection ??
I've seen a crimping tool for about 40 bucks and might come
in handy in the future, and the Sharkbite connectors are
around $9 each for 3/4, so a crimped joint would be about
a wash in cost for my present application....
I don't have any experience as to which is better.
But my guess would be that since you have an
old plastic pipe that is known to fail because of
deterioration of the plastic, that the Sharkbite or
similar where you can better control the amount
of pressure the fitting is applying would be better.
If it were me, I'd consider replacing the poly out to
the curb. But that also depends on the consequences
if it fails, ie exactly where it's located and what would
happen if it suddenly bursts.
After reading lots of stuff, I've decided to find my
my mattock and spade and dig another trench for
CPVC to the meter head....
Sometimes, claptrapping stuff together, when there's a
lot of "disagreements" as to the quality, is best approached
by working one's ass off for a few hours....
Fortunately, I only have 50-60 feet to dig... and I don't
have a "frost line" in my location and no required inspections
so I only need 12 inches of depth ------
I can do that in 5-6 sixpacks......
Thanks to all for the opinions.
.... Oh, and if any other readers have some knowledge
of a better way, which is easier, and more reliable....
please reply to this thread with your information...
Or 1" polyethylene, which would be even cheaper. I think
that's what they are using here in NJ in new construction
to go to the curb. Whatever it is, It's black, looks like
the poly pipe used for sprinklers, gets connected inside the
house with a barb fitting and double clamp. Copper for
60ft would be one hell of an expense.
$4 bucks a foot for 1"? More likely 3/4"
As opposed to poly which is approved and widely used
and just as permanent a solution for 40 cents a foot for 1"
or $24 instead of $240 for 3/4"
It's also a lot easier to work with than copper tubing.
If it's good enough for municipal water systems, it's good
enough for me.
If it were ME I would run the actual waterline inside a 3 inch or so
PVC pipe so no matter what the entire line wouldnt need dug up again.
Plus the PVC or conduit will provide physical protection for the
shallow buried line
I agree completely.... I had thought it a good idea to put the PEX
of some cheap Sched 80 PVC for the same reason, but not make
the joint connections -- just slip the PVC over the PEX and walk
it through---- just to use it for the added protection when I stick a
in the ground to plant a bush in the wrong place....
I routinely use that technique when burying UF electric for the same
reason....-- it's a pain to have to do splicing to replace a nick in
underground electrical cable....
I don't know whether code allows it or not -- I think it does --- but
it's a great idea nevertheless and gives me great peace of mind...
Your 3 inch conduit could be that cheap drainpipe stuff, and you could
pull stuff thru it in the future. A very good idea in my opinion, but
a little costly......I guess it depends on the length...
If it isn't sealed somehow on the ends, burrowing animals like
rats and field mice might set up house in it,and eventually decide
to sample the taste of the silly thing running thru the middle....
Perhaps you don't have critters in your area, but around here, we
have to worry about that stuff.... :>)))
