My black tank valve is stuck. Easy lube fix?
For sometime the black tank valve handle has been becoming increasingly difficult to open and close. Now it’s game on. It is next to impossible to close once opened. Is there a simple lubricant fix...

I replaced both of mine at the same time on one of my RV's. Took me more than 15 minutes.. I had the 4 bolt thing down pat, but getting the seal to stay in the right place took me a couple of hours worth of tries!
