Moving the water pump

Stevensusie · 02-25-2019, 11:51 AM

Has anyone had any experience moving their water pump? From my point of view, the only real drawback to these trailers is the lack of storage space. It seems odd that the manufacturer decided to take up 1/4 of the under-sink cupboard with the water pump when there is a large void behind the cool cat. Has anybody moved their pump, and if so, did you encounter any problems I should be aware of?

Someone at Forest River must have because that's how our A213HW is. The Coolcat is the black thing on the left.

Here's my space issue and the location I'm considering to move both the pump and the filter to.

Seems doable. Lots of plumbing.

Here's a different angle. The Coolcat is underneath the board with 'water pump' written on it. Fresh water pump is directly below.

While you're at it you might want to add a winterize bypass valve. Depending on where you live ofcourse.

Thanks OYO. I think I'm going to do it. My unit does have the winterizing accessories already. It gets cold up here.

Yup, that's cold. Congrats to you for camping in that!

Sorry I wasn't much help. Good luck with your mod and keep us posted.

In our 2014 A194HW the water pump is located under the heat exchanger air lines. I have to remove a couple of screws and a sheet of plywood to access it, but I only do that a couple of times per year. The pump is not even fastened down, just sits in place. Not sure if this info is helpful, layouts change a bit each year.

Moving the water pump to any location you want is fine. The one thing to watch out for. The water line to the pump has to be below you fresh water tank. If you choose too. You can mount the pump vertically with water lines at the bottom (Electrical protect in case of a leak)

Could you explain this? I'm not disagreeing, just don't understand.

Thanks

Hey OYO, What I was saying/ Water pumps can be mounted a;most anywhere you want to. What you have to make sure of. The pump inlet port has to below the lowest point the tank is (self pump prime). Also, if you choose to mount the pump vertically. Make the motor is above the inlet port (in case if a leak the motor won't get shorted out by the leaking water)

Nonsense. A-frame water pumps are mounted above the floor inside the box. Water tanks are located beneath the floor. Pumps are self-priming provided there is no vacuum leak between tank and pump. Tank must be vented.

OK pgandw your probably right. High end pumps have this feacher . But at pumps don't. After several years as a RV mech. It a standard rule we work to.

Part two, Vertical mounted pumps. Would you agree its best to mount it motor up

I had to replace the pump in my first A-frame (A122) because I ran it for hours without any water in the tank (I let the tank drain while driving home, pump was still on). Pump was mounted vertically, so I put the new pump in the same way.

But with the filter mounted on the shelf above, all my leaks were from the filter area. So the pump motor got wet just changing the filter. Never had any issues with either Shurflow pump getting wet.

I haven't looked carefully at the pump install in my new Flagstaff T21TBHW (A213HW). It's under the bed, so the filter is no longer above the pump. I did notice it's not a Shurflo this time when I moved the pump switch to relocate the front AC duct to face forward.

In an A-frame, it's probably easier to install the pump vertically (motor up) because it lets the inlet and outlet hoses lay on the floor. But frankly, I don't worry about it as long as it is not flopping around.
