Do all water heaters have a pressure relief valve of the type
with the handle to test them?
Ours is an oil-fired unit, works great, I drain out hte crud
approxumately monthly, give or take.
I was looking at the pressure relief valve today: There is no
mechanical way of opening or testing it.


Every one I ever saw had a handle. Could it be missing?

Keep in mind though, that often when you test them they do not re-seat
properly and will leak.
