Nick, can you have a dry system using PVC? I don't know much about
sprinkler systems but I'd guess that the average water pressure in a
home is about 80 pounds and therefore take more than that .... in air
pressure in the pipe..... say like ..... 120 pounds ???. So will PVC
stand up to the addional pressure necessary to maintain a dry system?
Or am I not understanding how it works?
