Our water level around pool is dropping pretty quickly and we are trying to pinpoint the problem. We live in TX so we cant find water anywhere because of all the rain. Ground is soaked anyway. So the water is dropping with the pump off. I turned the skimmer pipe off and it continues to drain. That leaves the main drain, correct? When the main drain is closed, the water stops draining. Now what do I do? I'm assuming this means there is a leak. Should I call a professional or are there ways to try to fix the problem myself? Any advice would be greatly appreciated!! Obviously I know nothing about pools!
