40 gallon State Electric hot water tank 5 or so years old in a rental trailer I own. Lots of lime in the water in the area. Lots of sediment build up 2 years ago when I last drained it. It had built up to the point where the lower element had shorted at the time.

That was then this is now. Tenant says it started to stink a couple weeks ago never did before. Also claims it is very weak on hot water and taking forever to heat up and little available. I am going to go drain it tomorrow morning so I want a feel for what to expect beyond what I did before.

I am thinking the lower element is buried and burned out again. I am curious about the coincidental stink though, any opinions before I go get dirty?????? Thanks in advance.
