We have developed a leak in the line that comes out of the pump into the filter. I am not sure what to use to repair it. Currently there is a large amount of a silicone product that has I guess broken down and in allowing the leak. Do I use more silicone or is there a better product to use? I want to get this fixed this weekend as it has gone from a few small "drops" to an all out steady leak when we are running the system.
