This pool season has been disastrous. We replaced a 3 year old liner right after we filled the pool up this year because of holes. The new liner seemed to be doing fine, but found there was a small hole last week, so we fixed it, filled up water, etc. I noticed today that the water was a bit lower than it should be under these conditions, so I went back to the "problem spot" and found 2 more small holes with water spraying out. These holes are constantly being located on the bottom of the pool. Nobody has swam in the pool for several weeks. What is the problem? This liner is only a few months old!
