Water Pump

The water pump on our 2008 Jayco Greyhawk 25 DB has become quite noisy and no longer puts out much pressure, so I want to replace it with a better unit. I've asked about the location of the pump on other forums, but the only answers claimed it was under the bed, which it definitely is not. The only thing in the sealed compartment under there is the fresh water tank and lots of wiring. No pump.

Both my wife and I are convinced the water pump is behind the headwall of the shower, probably at the height of the two faucets. The outside panel where I set the five valves according to the usage is also a possible access to the pump, as the panel is held in place with six screws.

I'd rather not just start exploring for the pump, and would like to have some confirmation as to its location from someone who actually knows what he/she is talking about. Can anyone help?

If it has become quite noisy, I would think it should be easy to find. With everything else off and quiet time, open a faucet. You should be able to determine where the noise is coming from and hence, the location of the pump. May have to remove a panel to get to it, but it should be behind the noise. Hope that helps.

It can't be to far from the water tank, these little pumps don't have much head lift to draw water very far. As Nam said you should be able to locate by the sound.
