You might need an attorney for this
I've never heard of PEX being that large. I've only seen it used for indoor water/heating systems (my home) replacing copper. You'd have to check to see if that size is available and suitable for in ground installation.
I know this is going to probably sound crazy, but what are the chances that a plumber can run 1.5 inch 200 psi roll pipe through the existing 2 inch line??? He would need to remove any sections of the pvc had have been repaired, but as long as the od of the 1.5 hdpe is less than the ID of the pvc it should work in theory..... any thoughts?
I say no way... too much friction over that distance. Maybe if you can get a string through via vacuum... then a stronger wire back the other way secure to pipe after smoothing the sharp edge on the poly. If there are any inside seams it will surely hang. Just my :2cents:My bet is , you won't get it inserted very far. If you are the type that has good luck, it will insert all the way. I'm never that lucky
:thumbsup: 100%For me Black Poly is the only thing - with brass fittings. I just replaced my 1200' run that was put in in 1973. The pipe was fine but the nylon fittings were cracking. We went with black poly with brass fittings. that is all they use around here.
Where I grew up in SD we ran water 1.5 miles in black poly pipe 6' deep Dad put it in in the mid 60's and it has never been touched and it has not had a problem. The rural water system they put in about 15 years ago out there was all done with black poly pipe knifed in.
If you do anything on your own the plumber will gladly just bow out. I am a fan of 180# black poly and was thinking about your situation and the fix you suggested. You won't get a roll of poly 1300 feet long and the 3 or 4 connections would not slide through a 2" pipe. It really is up to the builder to fix it right and sadly he may just fix the spot and call it a day, hoping that is all the leaks. Then another month later the warranty is off and you would be screwed big time. I ran black poly to 3 different houses and to barns with distances up to a couple hundred feet and in dirt rock crap soil. No problems in 30 years. In fact the only problem I had with any plumbing is in my current house with CPVC cracking inside the crawl space. If you are below the frost line and sandy soil I would not hesitate to use black poly. I would use a smaller pipe, maybe 1-1/4" and crank the incoming pressure up to 100# approx. and put another regulator at the house end and set to 50# or so. Saves on pipe material and a lot fewer joints, maybe 3 or 4 total. You need 4 full stainless steel clamps on each joint.
