I have a Wisperflow pump and it started not priming, running dry. I checked for leaks and found that both the threaded lines leading in and out of the pump are leaking. The inlet pipe is sucking air and the exit is leaking water. The pool is 2 years old and it looks like the installer put something on the threads that finally fell off. To verify the problem I put plumbers putty on the area and it sealed the leaks and the pump runs fine. Obviously this is temporary patch.
It there something I can put on the threads to permanently seal them?
