Can a polypropylene water main be repaired.?
I wanted to tap into a polypropylene water main. I had some previous experience with this type of pipe in my city. I tried to used a PVC barb fitting coupling with SS hose clamps. But these pipes have been in the ground in my city about 30 years. The pipe seems to be brittle with age. I had to use a torch to get the previous 1" pipe to slip onto the barb fitting. It held for about 2 months, then split and began to leak at the repair. My plumber friend tells me his company will not touch these pipes. They just replace the whole water main with copper pipe (for about $2200!).
