Hi all, I recently changed out my pool light from a regular incandescent to an LED. It was a traumatic experience. I didn't have any snorkel or scuba gear, so I had to keep going back down and busting up the mortar in the niche that surrounded the wire with a hammer and chisel. Well, long story short, after I replaced the light, I did NOT use pool putty to seal the wire in the niche. I figured 'what's the point?' Well, apparently, there might be a point...which I don't understand. The pool appears to be losing water at a rate much more rapid than evaporation. I live in FL and it's hot here, but I'm losing about 2 inches or more a day. I've never done the bucket test, but will do so to make absolutely sure.
Anyway - can somebody explain to me why not sealing the wire with pool putty has resulted in this apparent leak? Could there be a leak where the niche pipe goes back to the electrical outlet junction box (where you wire the light)? If so, wouldn't there be evidence of a leak...like very wet grass/soil underneath the electrical conduit? Could this be a red herring?
Any advice would be greatly appreciated.
