We just started our pool build last Monday. We are on a well and I would like the pool's auto fill to be hooked up to the water that is softned by our softner. Our water is hard and it also has alot of Iron in it. It would be an easy hook up. What are your oppinions about this. Our plumber said he would do what we want. He also said that it wouldn't be worth it. that it would waste water. I don't see how? any insight would be welcome. I will post pics as i have many.
