Where does my water go, Afica or Mexico?? Pool is IG steel wall, vinyl lined 2 years old. About 60,000 litres, 16' x 32' straight back kidney about 5' deep. One skimmer, main drain, side suction and two returns. Cartridge filter and salt. I have full sun on my pool from 10:00am until 8:30 pm. Pump runs about 8-10 hours per day. I'm losing about a 3/16 inch of water per 24 hours and wondering if my pool leaks or if this is a fairly normal evaporation rate. Not sure if PB is being straight up with us or not. Have yet to test if water loss is only when pump is running but much rain in the forecast so can't test this for a few days. Pool temp goes from about a high of 78 to lows of 71 overnight, solar cover on when not swimming but for small spot at the stairs. Any thoughts out there about evaporation or should I start trying to find leak possibilities. Liner does not seem to have any holes or tears.
