Leaking hot water tank’s pressure relief valve

[Lshulan]

On my 2002 mainship 390, the pressure relieve valve on the hot water tank has a slow drip. It appears to just be screwed in, anyone have any experience in removing and replacing one? I’m concerned I’ll wreck the tank if I puts a big wrench on it and break something

That is always a concern. Be gentle. Upon re-install, use some kind of non hardening pipe dope with teflon. It will prevent galvanic corrosion with dissimilar metals.
