Help! We have a 3 year old intex ultra frame 26' round pool. Late last summer, we seemed to be hoping it off more than usual, but we knew our heading system dropped some, so we thought that was the problem. We made plans to improve it this spring. Our spring has been miserable, so we got a late start. We just got it filled on Monday. Then we left for the holiday on Wednesday, with just the pump running. I got a text from my neighbor on Saturday telling me that they had shut our pump of because the water level was low. We got home today and it is about 6" low. We had a lot of rain over the weekend, so we think we have lost several thousand gallons. It doesn't seem to be getting lower. All signs point to a hole in the side somewhere, but we see no signs of wetness anywhere on the sides of the pool. Any suggestions?
