Hey all, Just bought a house with a pool. The valves on the pool are not marked and I am a bit confused. Could anyone help identify all the positions. I am a pool newbie. So any help is appreciated. (I'd like to know which positions to keep the valves at normally, how to activate spa jets, and water heater line,for spa and pool, and draining, as well as skimming, and filter positions).
