Results for "underwater lighting"

Wondering if I should be concerned about water pooling around the light fixture in this rental's inground pool since I've never dealt with pool lights before. My pool has been losing water steadily for months now, and I've checked everything I can think of - the skimmer, return lines, you name it. But I just noticed the water level seems to drop more when the pool light is on, and there's some discoloration around the light fixture.

Is it actually possible for pool lights to leak? I never even considered this could be the source of my problem. If they can leak, what parts typically fail and how much water are we talking about? I'm really hoping this might finally be the answer to my water loss mystery!…more

Got my pool water level dropping a massive 2-3 inches this week and there's definitely something wrong beyond normal evaporation. My water chemistry is balanced (chlorine at 2.5 ppm, pH 7.4, alkalinity 120 ppm), so I don't think it's a chemical issue causing excessive evaporation.

I suspect there might be a leak somewhere but I'm not sure how to pinpoint the exact location. Should I be checking around the skimmers and return jets first? I've heard about using food coloring to detect leaks but I'm not sure of the proper technique. Also wondering if there's a way to test whether it's a structural leak versus something in the plumbing lines.

What's the most systematic approach to track down where exactly the water is going? I'd rather diagnose this myself before calling in a expensive leak detection service if possible.…more
