OK - I am afraid I have to say me too.... I have joined the club on this issue. Purchased a pool and right away noticed it leaked a bit. Once 1 week or so I had to blow it back up. Was not concerned. Leak got worse to every day it needed it. I looked all over for the leak, soapy water, listening etc... Could not find it. Intext said sure... send us the pool back and if we deem it a defect we will replace the pool. Might take a few weeks as we are busy! So that was a no go. Bit the bullet purchased another one. Worked great for three weeks. Then leaks, then bad leaks. I was pretty much ready to drain the pool, attack it with an axe, pour gas on it and tell the kids it is bonfire time. Then a remembered an earlier comment about a cat being to blame. Well our neighbors have a cat (and I like cats) but this thing wonders all over the place, kills everything he can AND climbs on the side of their metal frame pool. So I go out, blow mine up and with an eagle eye, and with my kids looking we find one small hole and one large. Put some temporary tape on them and sure enough that has done it. Will replace with a real patch this weekend. So I guess I left the ladder in the pool and the cat climbed up. I hope by removing the ladder the cat will not try to jump up onto it. Certainly I have no proof it was the cat but am planning on telling the neighbor he owes me a beer for the aggreviation! If I get more leaks I will do either the pvc solution or the 6 inch ventilation tubing in the ring. Two very creative ideas!
