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.

Mine came out easy and new one installed.
If it does not unscrew easily, tighten then unscrew, rinse repeat

Thanks to both of you, will give it a try when I get back to the boat. But one other semi related question, is there an anode in the tank and if so, how to get it out for replacement. Ideas? Experience? Are both the relief valve and anode standard items?

You might spray some corrosion lubricant on the threads a couple of days before you try to take it out. If it doesn’t want to come out try some heat with a heat gun. Some have anodes some don’t.
