I have an in-ground, pool connected jacuzzi that is made from concrete and has Pebble Tec for a shell. I have determined the leak to be coming from somewhere between the face (front side) of the jet and where the PVC pipe exits the concrete shell in the rear. The water actually leaks out of the jacuzzi from between the PVC and the concrete. I had to dig down about 5 feet just to reach the pipe as we have a large flower bed built up and behind the jacuzzi (lucky me). Oh, did I mention the waterfall that feeds the jacuzzi? Should I send a photo named "I believe I know the issue but don't have a freakin clue how to fix it?"
