Rust around boiler pressure regulator nut
Hi everyone, this past winter I had some water coming from my TP valve of my boiler. I replaced the pressure regulator which resolved the issue. However, I noticed that there is some significant rust around the nut connecting the pressure regulator to the incoming water line. Should I attempt to unscrew the nut and Teflon tape around the threads before it gets any worse? The previous TACO pressure regulator valve that was in place didn’t have any Teflon tape so I didn’t bother to use any with the new one. Thanks for the help!
