As for the 2 year old valve on my FOWLR, that sucker gets opened weekly with every water change (or two weeks if I'm being lazy). It is part of my water change system so gets opened and closed quite a lot.

5 years between 2 of them sounds pretty convincing! A person could put in a ball valve also I guess for water changes but I wouldn't bother with that. Are yours sched 40 or 80? What brand are they? Do you know what your gasket type is on yours?
