Hoping somebody can help me here. I have an 18' above ground pool that (to my knowledge) had not been leaking during the summer months, judging by the level staying fairly consistent with evaporation, rain, etc. After covering it this fall (we use a mesh cover) and putting on an Aquador skimmer cover and ice pillow, I noticed after about a month, the ice pillow looking lower than it should be. I uncovered the pool and saw the level down below the skimmer and return. However, the Aquador cover had developed a crack in it, so I thought that might be some of the problem.
No such luck. I measured the water level last week with a stick, marked it, and checked again this morning. It's down abnother1" (approx) in one week's time. Since it's below the skimmer and return at this point (about 4" below the return), I'm assuming the leak is at the bottom drain or somewhere in the liner at the bottom. My question, since we now are getting into the point where the water will be freezing, is protecting the pool walls from collapsing. The cover is about 13 years old and being held by pool clips and the ice pillow in the middle. Any suggestions would be welcomed greatly!
