I tore the front of the pump apart and cleaned it up a bit and then tried to run it again. It works when recirculating the HLT, but it's pulling a bit of air in, but not leaking. When I switched to the HLT, I think the bit of air being drawn in was too much for it to push the water. I'm going to do some shopping for o-rings and what not, but it's good to know the heating element still works as well as the pump.
Without knowing how long this thing has been sitting, since it comes in contact with the wort, it'd probably be a good idea to replace that heating element and tubing to and from the pump (the vinyl hoses, not stainless plumbing) right?
