I live in Ft Worth, TX and my house is about 20 years old.
It has a blue, 3/4", plastic line from the house to the water meter
(about 50') and it has just cracked again. The first time it cracked
was about 4 years ago and I'm wondering if there is a better quality
plastic pipe available now, or do I need to replace it with a copper
Your advise will be appreciated.
The current PEX products have good reviews in water service, but
perhaps your pipe, if PEX, was exposed to UV light which is said to be
damaging. Depending on the pipe composition, you may have some
warranty rights. Polybutylene installations come to mind.
A former neighbor had a plastic pipe line from the street to home
break underground. His problem was tree roots. It was replaced with
PEX is now used in the desert in landscaping, covered with rock there
is no UV damage I know of - so far.
ThermoPex is insulated for underground use
Check with plumbers near you. What comes to mind to me, is
that the ultra violet light in sunlight is destructive to
most plastics. Maybe you can shade the pipe, or wrap it some
how. Keep the sunlight off.
It's probably the new Pex stuff.
?????? In that case it wouldn't have been the UV it would have been
freezing in all likelihood.
I've never seen a water service line exit the ground and enter a
residence above ground outside (even in E TN/KY)...
Schedule 80 (the gray stuff) would be an upgrade, should last as long
as you do.
If you change it yourself, check out the Sharkbite fittings, easy to
use and good cross material compatibility, bury-able.
A tad expensive at around $5 each, but compared to plumber time @
$100s per hour, not so bad.
run water line inside of a schedule 40, 4 inch PVC sewer pipe.
since you must dig, dig one last time:)
After that any line failure? just snake new line thru sewer pipe.
protects PEX from tree roots and mechanical damage of any type. plus
its realtively cheap, and makes future line replacement easy
That is a great link, Eric, thanks.
I fixed the leak in the pipe by cutting the pipe off, where it was
leaking and then using a couple of 'sleeve' fittings.
When I turned the water back on at the meter, there was still a leak
but it was from the connection to the meter.
My girlfriend explained to me that it needed some type of washer
( DUH !!) Why didn't I think of that? :-)
Anyway, I walked up to the Water Authority, where they were very nice
to me and gave me 3 washers, of different thicknesses and told me that
the blue plastic pipe that I have is not used any more. The Gentleman
did suggest that I could use schedule 40, white plastic pipe.
I know that the gray, Schedule 80 that you suggested would be stronger
but would the ID then be smaller and flow less water?
Nobody else said it, so I will- in previous threads on here, people have
mentioned that parts of TX have a unique clay soil that can move around
with seasonal humidity changes. Perhaps OP needs something other than
the native soil as backfill around the pipe, or some sort of flexible
connection that won't strain the pipe when the earth moves?
Hey, I'm a northern boy- we put water pipes 3-4 feet down up here, and
sometimes they still break due to frost.
I have an 79 year old house (OC SoCal) and I can tell you that as
good as galvanized may have been (lasted 50 years & then some but with
greatly reduced flow) it is NOT the best choice based on the local
water chemistry. Copper has lasted 50+ years in this area with no
significant loss of flow. I re-piped w/ PEX due to ease of
installation compared to copper.
I wouldnt bet on currently available galv plus considering the effort
involved....... The suggestion of a galv re-pipe would be DOA.
OP- Determine what kind of plastic was used & way it failed before
you commit to a copper or PEX fix. Was your failed water line solvent
glued? or crimped?

Don't suppose you can get the meter put closer to the house, can you? I
assume at anything upstream of the meter is the water company's
responsibility, so then they might use something better and also fix it if
it breaks again...
OTOH I've seen plenty of buried (assuming yours *isn't* above-ground)
plastic water pipes and they last without breaking, so I think there must
be something unusual about your setup (excessive strain on the pipe,
vibration damage, not deep enough and someone driving something heavy over
the top of it etc.)
