Keep the pool filled to its normal level with the equipment in working order, and note what you have observed: how fast the level drops, whether that changes when the pump runs and where the ground is wet. Testing goes faster when the water is clear enough to see the floor and fittings.
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.
