Bought a 24' round above ground pool this year, used TFP bleach method and successfully kept it clean all summer for the family to enjoy. Where I live, freezing won't be an issue, but leaves falling in the pool will be a problem. For the past couple of months I've been running the pump a little here and there, running the robot vaccum weekly, and adding a gallon of bleach from time to time - no problems and has been crystal clear. I planned to keep doing so throughout the winter so at least we'd be looking at a pretty pool. Unfortunatly, I have a leak that started two weeks ago and am loosing about 1/2 inch per day. So far, I'm just adding water a couple times a week, but I think I need to take action. The water is too cold to go swimming looking for the leak. I worry about a collapse if I simply let it drain and repair in the Spring. I'm concerned that an ongoing leak will eventally create a cavity under the pool. I have no clue where the leak is, only that there is a wet rim around half of the pool (which may or may not signal a vicinity because it happens to be very slightly lower in grade). The leak is below the skimmer and the wet gound confirms it's not an issue with the pipes/filter/pump which are on the dry side of the pool. I wonder if I could drain the pool one day, repair the leak and refill over the next day? I'm assuming this is not an option due to the cold and non-pliability of the liner. If there would be no damage caused by the leak, I don't mind just adding water weekly to keep it full (I'm on a well). Apprecaite any advice. Thanks.
