Good Morning! I have a inground 16x32 rectangle pool built on a piece of flat land with an adjacent slope. There is a puddle of water that started about 5 weeks ago on the down slope of the yard. The pool water level decreases at pump rpm at 1500 to around the second screw on the skimmer plate. When the pump rpm increases to 3000, the pool water level increases in between the second and third screw on the skimmer. When I turned off the pump, the water level dropped below the second screw on the skimmer plate and stayed at that point overnight. A leak specialist came out and added a cutoff valve in the french drain/skimmer valve line because he stated the original valve was leaking through. He did isolate all the plumbing and nothing leaked down. The yard still has water standing and the water level is still dropping. Help?
