I just cut an old and leaking threaded fitting off of the intake side of my pump and replaced it with a pump union. I used a bit of thread tape on the threads. There was some old residual sticky sealant in the pump housings female threads.
Unfortunately, my fix was no-fix and I now have a significant amount of air entering the pump basket. Using the hose trick, I think (and hope) that the leak is actually the union's threads where they enter the pump housing. My assumption is that I need to unscrew the union and apply some type of sealant to those threads.
Yes or No?
If yes, what type of sealant is best for this application?
If no, which mallet shall I use to smash this thing all to bits and then whack my forehead with?
