the plumber gave us an option of copper pipes or pvc where the turn on valve attaches to the house for the 2-3 feet that is sticking out of the ground. he said most people get pvc but a few people ask for copper. he asked us because we were inquiring to make sure the hose bibs we got put on as an add-on in the backyard were going to be copper instead of pvc on the part that is sticking out of the ground. we told him copper until i thought about the folks who try to clean their pools with copper. if the water passes through a copper pipe is that similar to the copper cleaning systems and so should we stick with pvc so to not effect ph or getting green water or anything like that? thanku!
