Location of water pump

[sherol roy]

We have a 2011 Avalanche 290rl and can’t find the water pump. Any ideas?

Probably behind the pass thru wall.

It is pretty easy to hear the water pump in operation. A little water in the fresh water tank, open a water tap and you should be able to locate it. Mine is behind a panel under the kitchen counter top. If your pump is in the pass through, stick your head in there and listen while a tap is opened and there will be a panel that you unscrew to get to it.
