Frustrated with Vortech

[Der_Iron_Chef]

So, I hooked my newly-acquired Vortech up to the side of my newly-acquired aquarium yesterday. Easy peasy, lemon squeazey.

But, honestly, the noise bothered me. I never seemed to be able to hit the "sweet spot" and get it to just "hum". Today it randomly started emitting a high-pitched squeak/squeal that obviously wasn't okay with me. I thought maybe it had to be the gasket vibrating against the glass.

So I took it all apart tonight, and discovered that two of the three rubber "pins" that hold the motor assembly and pin spacer together were sort of bent. I tried to put it back together carefully, and put it back on the tank, and all was good. No squeak/squeal, and the quietest its ever been!

BUT. Now it's constantly overheating. It will run on Lagoon Random for a minute or so, and then overheat and stop itself. This has been repeating itself for the last hour or so. I've read the manual, and it says that this is possibly due to a misalignment.

So I'm wondering....do I have to live with either a squeak/squeal or a constantly overheating pump? These can't be my only options.

Grrrr.
