Losing a quarter of an inch a day is normal evaporation for most of the year here, and up to half an inch is normal through a hot, windy summer. Loss approaching an inch a day, day after day, should be treated as a leak until proven otherwise. Two inches a day is clearly a leak, and you should call us the same day.
Measure at the same spot on the tile line at the same time each day, with the pump off if possible, so splashing and the pump’s operation do not skew the reading. Heavy rain can hide water loss for a day or two, so measure again once the weather settles.
Still not sure it’s a leak?
Describe what your pool is doing, and we will tell you what it may be and what a visit would involve. If the water level is dropping fast, call us right away.
