Can't find my water pump

We have an 2015 keystone alpine 3010re and I am trying to find the water pump I have taken off the 3 panels 2 under the kitchen sink and 1 in the bathroom and can't find it. I ran the pump and can hear it but I am afraid to run it for too long as I don't want to burn up the pump. It is new to us and we are using it for the first time. I filled the fresh water holding tank and but the water heater bypass to off I have the selector to normal and I can hear the pump but it is pumping water to the faucets. Any help will be greatly appreciated

So sounds like the rule of thumb is "The pump should be close to the freshwater tank. Or not." and "The pump should be close to the water heater. Or not." and "The pump should be near the kitchen. Or not.".

Or in other words, until you find it, you won't know where it is, different RV's put it in much different places.


So true! I've had 8 now and they were all different. I've always found them by accident or followed the noise. They put them in some strange places sometimes! The Airstream was the worst! 31' Rear bath, fresh water tank in the rear bumper / storage area behind the tub. Kitchen was 3/4 ways to the front, then a pretty large living area. The pump was in the very front under the couch. 25' from the tank and bathroom and 5' outside the kitchen!

If there is a removable panel under the oven take a look. That is where ours is.

On my last 2 5th wheels the pump was accessed from the basement storage. On my Laredo I had to unscrew a panel on the back wall of the basement to reach the pump. That was on the passenger side. On my current trailer, the pump is accessed by a door on the back side wall of the basement.

Do you have a gravity fresh water fill, not the city water connection if different. The pump should be very close to the fresh water tank, which also close to the fill.
When I winterized my neighbours 5th wheel a few years ago, I had to search for the pump and winterizing line. She told me that she had always put 10 gallons of pink in the fresh water tank and pumped it through. Long story short. City water conection near the front under the bathroom, upper level, Gravity fill in the rear wall, fresh water tank under the floor just in front of the bumper, could't get any further away from kitchen or bathroom. The water pump was on the floor inside an end table between the recliner chairs. When all was quiet, you could hear the pump running. I had to dig through carpet and trim just to remove this end table and access the pump.

At least in my Alpine, which is the same year so should be more or less the same, there is no gravity fill and the pump is about 25ft from the fresh tank. Fresh tank is at the very rear, and pump is in the front basement behind the water works and a false wall.

Mine is in the basement, behind a false wall behind the water center. It's the same year Alpine, but a 3730FB. I'd bet on more or less the same location on yours.

You will not burn up the pump by letting it run dry.

When I was looking for my pump, it was easier to locate it by sound from beneath the RV. When I was inside the RV, it sounded like it was under the sink near the water heater, but after crawling underneath the RV, it was easier to hear that it was actually under the bed (which as it turns out, is where the freshwater tank is). The bed base isn't hinged so it can be opened, if I remove a small under bed drawer I can see the pump, but if I had to service it, I think I'd have to unscrew the bed base to reach it.

Even now that I know where it is, from inside the RV it's hard to tell where it is from sound alone, the sound travels weirdly.

I would be very surprised if you could hurt the pump by running it. I accidently left mine running in our last 5er for a day and a half before I discovered it. It happened at home and I had no water in the tank. I replaced the pump, and now I still use that pump to transfer water from jugs to my fresh water tank.

I agree the post is a little confusing. Just remember the pump has to fill up the water heater before you will have much pressure to the faucets.

the pump is usually close to the back of the water heater.

Most pumps can be run dry for a while, with no fear of damage/burnout. It will be near the fresh water tank, and may be behind a panel best accessed from the pass through. Mine has a square cover, over a hole in the panel in pass through/basement.

Your post is a bit unclear, are you saying it is pumping water to the faucets? If it is, what is wrong, and what are you asking?

I would look in your outside hatch, and I bet if you look around the wet bay theres likely a false panel between the nylon wet bay and the pump/hot water tank and valves. If its running then either your hw tank is still filling or you have the valves set wrong and its sucking air possibly through the winterizing tube.
