Hi All. My friend's newly built pool is losing 3" of water each week and she's wondering if that's a sign of a problem, or could just be evaporation as her PB said. I told her I'd ask the good people on this forum for her. Our pool doesn't have water yet so I couldn't offer any first hand feedback, but I'm sure someone here would have some thoughts for her. She lives in Anaheim Hills, CA (Orange County, Southern California) in case that's important to consider the evaporation theory. Plus her pool is on the small side, I think something like 15' x 27'. Thank you.
