I drained my inground pool today below the level of the light, and its been draining water for over 12 hours. You cant actually see running or dripping water, but the wall below it is constantly wet when everything else is bone dry. If I remember correctly, it did it for DAYS when we had it re-done. The guys told me that was normal, but that makes no sense to me. If its groundwater coming out of the light, why wouldn't pool water go into the ground? Weve got a significant leak somewhere, but I always figured its the cracks we are dealing with. Could the light be part of it? I've never pulled it out, so I don't know whats behind there, but it must be just a conduit or something for the wire to run through, right?
