I have a sand filter that is leaking. There is a small leak on the side of the tank and it was spraying out a very fine stream of water. I found some epoxy putty at the hardware store and put that on and it slowed it down but am wondering what to do for a permanent fix for this season. I do have another filter that I plan on switching out next year. Does anyone have any experience with this? I am open to any suggestion. Thanks, Penny
