I had a cracked on my main water supply pipe (one inch diameter PVC pipe). There is a water pressure regulator to lower the city water pressure coming in to the house. The crack happen about halfway (10 feet) between the city water meter and the pressure regulator. The PVC pipes are underground (7 years, not that old). Plumber fixed it, but did not have a clue as to what could have caused PVC to crack. I suspect that somehow my water pressure regulator (due to the city high water pressure) is causing my pipes to flex or oscillate underground causing then to crack (which means it will happen again). Has anyone seen this before? Any permanent fixes? Thanks for the help...Jose
