BeachBreeze, your ideas won't apply here as last Winter the level in the pool was well below the pool light and skimmer lines (2 feet or more) and likely below the level of where the pipes emerge for the filter area. The only logical conclusion I have, given that the leak specialist only found the small hole last Fall, is that they leak is either around the main floor drain or on the piping returning the main drain to the filter. I've been focused on keeping the pool clean and with the tons of water this past 2 mos the level hasn't been an issue until just this week again where I have started to use the hose to maintain water levels above the skimmer/return lines. I got the fins and mask to check out the main drain and try to plug it, I just don't have the breath-holding capacity ....yet.

No, the leak didn't stop, likely that I had 2 and only patched the one which again looked to small to cover the amount of water loss. I guess I will try and plug the main drain and see if the affects it.

I had noticed a loss of water for last two seasons, and noticably last Winter where I lost almost 3 feet of water. So, this past Summer I had the Man out to find and fix the leak, the one he found on the bottom slope seem to be too small to be the real problem, but I'm not the expert. So, now 6 mos later, I'm still seeing water loss with the pool closed up...probably several inchs a week. So, I'm guessing I have a main drain problem as the water is below the return lines and the Man didn't find any other leaks around the pool. So, with the water level lower, I can try and get a dye test to see if somethiing gets drawn into the main drain. then I can try and cover the drain to plug it and see if level doesn't drop. I see that fix-a-leak can be applied though not sure how effective it would be getting to the actual leak without and suction on the line. And, I see we can choose to plug the main drain. Curious what comments the community has as I look to open the pool in the next 30 days.
