Kicking my butt

I have an inground pool. It is about 36,000  gallons and 25 years old and has a sand filter. I am losing approximately 1 inch of water a day. I have replaced the spider gasket and the spring on my multi port valve. I do not believe it is on my suction side. When the system is running I see no air bubbles in my pump lid. When I  shut off the system I can see the water level in my pump lowering. Each time I turn the system on it has to re-prime. I live in the Midwest so I do not think of evaporation is equaling 1 inch a day. I will do a bucket test this weekend. There are no visible cracks in the pool surface. If I let it go long enough it will go below my skimmers ruling out the skimmers as a potential source of the leak. Due to the placement of my discharge pipe I cannot see if there’s any water running out of it when the system is off. Does anybody have any suggestions or guidance on where I should check next? Thank you.

Thank you for contacting Inyo. You can use the phenol red liquid from a ph test kit to locate a leak. With the pump off, squeeze a few drops near suspected leak areas. Common areas would be in skimmers, lights, return jets, and main drains. If there is a leak, the red liquid will be drawn in.

If it's not in one of those common areas, we recommend hiring a leak detection company.
