What I want to know is, where the feck is all this crud hiding??

Are you sure the bottom of the tank's not scaled up, with the crap
hiding on top (and the scale acting as a filter when you use the
drain tap)? I attacked ours a couple of years ago after performance
started dropping off, and probably the bottom ten inches or so of the
tank was full of scale.

The tank is only 3 years old and we live in a soft water area so I'm pretty
sure that scale isn't a problem.
