Let’s talk about Elevator valves (Maxton, EECO & Blain) and the thread sealers you use for the pipes in/out of it. When its not a VIC we use a variety of compounds depending on jobs but lately I feel like they are all leaking no matter what we use. Some of my plumber friends told me to use Teflon tape and blue monster ptfe sealer. I was always told to use one or the other but never both together. Trying to see what others use to seal valve pipes to prevent leaks. I know one company uses some epoxy that destroys the valve threads because you cannot separate the pipe and valve even with a lot of heat.

What do you use? What do you recommend being used?
