Mark P Posted November 21, 2006 Report Share Posted November 21, 2006 First time I've seen this type of pipe - blue seemed to be some sort of plastic. This is the main line running in from the curb side meter. Is this PEX? Download Attachment: 1.jpg 75.99 KB Quote Link to comment Share on other sites More sharing options...
Les Posted November 21, 2006 Report Share Posted November 21, 2006 Mark, it sure looks like Shell's "Big Blue". I have never seen it that dark in our area. Google up big blue pipe for details. Quote Link to comment Share on other sites More sharing options...
paul burrell Posted November 21, 2006 Report Share Posted November 21, 2006 This is polybutlyene known as "big blue". It is used in my area quite a lot. Old poly was 150 psi from street service entrance that failed on a large scale and is not used anymore. The pressure rating has been raised to 180 psi and I have seen 220 psi, both are acceptable. If you can see enough of the pipe there is a pressure rating on it. 150 psi NO good: 180 plus psi OK. Poly plumbing lines both from street and branch lines in home are a blue heron in my area. Some sellers have to discount price of home to sell with poly system. Same thing for Louisiana Pacific hard board siding. Paul B. Quote Link to comment Share on other sites More sharing options...
Mark P Posted November 21, 2006 Author Report Share Posted November 21, 2006 Thanks for the info - could not read any markings - everything else in the home was copper - this is new construction in an old neighborhood Quote Link to comment Share on other sites More sharing options...
paul burrell Posted November 22, 2006 Report Share Posted November 22, 2006 Mark, If it is new construction it is most likely OK I have not seen the old discontinued pipe in quite awhile. I would not be concerned about it. Paul B.

chrisprickett Posted November 22, 2006 Report Share Posted November 22, 2006 Is that wall concrete? If so, the piping should be wrapped or sleeved to protect it. Quote Link to comment Share on other sites More sharing options...

Quote:Originally posted by AHIS Thanks for the info - could not read any markings - everything else in the home was copper - this is new construction in an old neighborhood Les & Paul are correct - That is Poly Butylene (History of multiple failures) it was used in water service (main line to the house) into the late eighties/early nineties - I've seen entire Mcmansion developments with failures left and right with this stuff. Don't miss something like this cause a water main replacement is about 3G's... See here http://www.spencerclass.com/index2.htm Quote Link to comment Share on other sites More sharing options...

Darren Posted May 25, 2007 Report Share Posted May 25, 2007 Now correct me if I'm wrong; it the fittings that fail. How would the service line (like the one pictured) fail. The connection to the meter is not the type that fails is it? Darren www.aboutthehouseinspections.com Quote Link to comment Share on other sites More sharing options...

I've seen that pipe after it's been dug up from the yard, it just splits down the middle. Unlike the cross linked Polyethlyne, it's just basically weak plastic, guess it just can't take the pressure. Weak plastics don't need much excuse to split. Take a piece of 1/4" acrylic (plexiglass) and clean it with an amonia based window cleaner or cut a square out of a corner of it, leaving a sharp inside corner, and you'll see what I mean. Maybe it just takes a little crunch from rough backfilling to weaken its structure then just starts spliting and creeping from there. Most of the problems with distribution piping inside the house have been from the fittings but not always, sometime the pipe just cracks.
