I had two leaks in my pad. One was where all the tubes connect together at the top of the pad. The other one was in the middle of the pad. I had to make a cut in the pad to expose the tube in the middle of the pad. It was just a small pin hole. I used Rust-Oleum Leakseal to stop the leak and wrapped the tube. It has worked for about a year now. For the leak where all the tubes meet up at the top of the pad I cut the pad again to expose the connection point. On my pad there are 5 individual hosed that run in the pad. The connection point is a splitter. You have water that is pushed into the pad on one side and water pushed out of the pad on the other side. I then pulled the tube off the connector and cut the tube where I had a hole and placed it back on to the connector.
