It means the leak is at, or just above, the level where the water stopped. Water cannot escape through an opening it is no longer touching. A pool that settles at the bottom of the skimmer opening usually has a leak in the skimmer body or the seal between the skimmer and the shell. A pool that settles around the light is often leaking through the light niche or its conduit. A pool that settles at a return fitting has a leak in that fitting or its return line.
Do not let the pool drop further to find out. Refill it to the normal level and call us. A pool left low in coastal ground can lift or crack, and a low water level puts the pump at risk of running dry.
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.
