Received a call that "I think I have a leak". Found this slip coupling on the main line. 1/4" in on one end and a bunch of glue inside, I pulled the pipe apart by hand... I fix more leaks that wet or shine /blue glue is used by a contractor, I hate that stuff.. Plus today I looked at another job with leaks, turned out the Water company increased the pressure in this one part of town to 240+psi , that's right 240+psi . I asked the homeowner to flag the places that he felt there was a leak. From the POC he marked it about every 20ft and I counted 10 flags.
