Black poly pipe leak at coupling
Here's a first, at least for me.
A customer of mine's poly line developed a crack halfway to his house, shortest distance would be 120 feet.
The mains are running high pressure with the homes having PRV's.
The new black polyethene fits the brass insert couplings fine with no leaks.
However the old black poly pipe that has been under high pressure for maybe 20 years seems larger and doesn't seal.
Has anyone else encountered this before?
I've patched poly before with no problems, but I'm thinking that maybe the old pipe has grown in size over the years.
