We have experienced catastrophic/basement flooding leaks using Schedule 80 = piping on our well water treatment system 3 different times now, even thoug= h the plumbing was installed by two different experienced, licensed plumber= s who both claim they have never seen Schedule 80 piping fail in this way. = =20
The main plumbing in our house is copper. The water comes out of the well = pump (60 psi) into white plastic (Schedule 40?) line and then flows through= Schedule 80 piping to a retention tank and then through Schedule 80 piping= again to copper piping to the filtration/water softening tanks which have = Schedule 80 joins then back out into the copper lines to the house. Our we= ll water has a lot of sediment and iron in it but generally no other harmfu= l chemicals.
The first two leaks occurred when the Schedule 80 pipe cracked at the join = with both the filtration and water softening tanks. The first plumber appe= ars to have replaced the Schedule 80 pipe with Schedule 40 pipe and it seem= s to have fixed the problem (although our second plumber is confused as to = why Schedule 40 would work when Schedule 80 did not). The third time we ha= d a failure it was at the elbow join between Schedule 80 piping from the re= tention tank into the copper house lines. The join split completely.
I am just curious if anyone else has experienced this and/or if you might h= ave any explanations why this occurred or what to do to prevent these break= s from occurring in future. Thanks for any information!
