I just recently moved into a home that had a pool/spa. I really like the layout, but I am finding difficult to figure out the system since the previous owner had a pool service. So he was not much help when it came to ask questions about the pool plumbing
So I figured out that it could be why the spa is draining down when pool pump turns Off. It has to be a check valve. But I cannot find a check valve in the pluming.
perhaps I have an ortega valve behind this plug??
Thanks in advance
we just had a storm here in Houston so I am doing some cleaning . but this is what it usually looks like.
