Earlier this spring, while I had the pool drained and taken apart, our Christmas puppy chewed the threads where the hose comes from the skimmer into the sand filter pump (see pic). At the time, I wasn't too worried about it, because the pipe would still screw onto the threads, so I thought it would be okay. Now that we're setting up the pool, the connection is not sound--it drips at a rate (my husband says) of about 2 gallons per hour. We tried applying pipe tape to the threads, but it still drips... any suggestions, or am I going to have to buy a whole new filter?
