Noise Under Sink - Heater?

[masterdrago]

I discovered a crazy rumble/vibration coming from what sounded like the furnace. A mild vibration on the counter between stovetop and sink. Seriously sounded like the furnace. After taking the outside furnace cover off and hearing the sound was not the furnace, it dawned on my silly head that it might be the water pump. We had used it during the trip home last week. Sure enough, the pump was still on. I'm suspecting that there was not enough water in the fresh tank to allow it to pump to the shut-off pressure, as only water/air came out the faucets.

I went out to look at the convenience center on the drivers side passthru and the noise was not there. I thought the pump was behind the convenience center, not at the furnace. Anyone have hints where it might be?

My pump is under the counter right beside the furnace on my 2400. I am sure yours is in the same area
It sounds like you have determined the noise anyway

Yes, it's next to the furnace. You need to remove the large pot and pan drawer to get to it. Hopefully it is not damaged from running that long (probably without water in it?).
