Usually and water pump location are not used in the same sentence in the RV world. They are hidden everywhere. Many times found BEHIND wooden panels held in place with #2 square drive Screws. Best way to find it is turn the pump on and listen. Turn a faucet on and walk around the inside and outside And listen for it. I can hear mine at the kitchen sink and it is in the pimp is in the pass thru storage area behind wooden panels which I removed.
