Cleaned the lime buildup out of the water heater tank. We were running out of hot water waaaaay earlier than we should have been, so I figured it had a few inches of lime in the bottom...
more like 8 inches
I filled up the shop-vac twice. Also replaced the bottom element since it was caked with the stuff, and looked really bad. They're only $8.97 anyway, so not much to lose.
