Water Pump Position wall or floor

[Tony S]

Hi Folks

I was hoping to get an opinion or two about water pump position. Is vertical on a cabinet wall or flat on the floor the preferred position. Of course, vertical takes up less floor space but is there any performance difference. Any other advantage or disadvantage.

Thank You in advance

Tony

Floor is the RV Industry standard.

Would it be harder to initially prime when higher? Would it have trouble draining for winterizing? Does the mounting instructions give advice on position?

[JStanley]

Interesting question. Since it’s essentially a motor attached to a pump, I don’t think it makes any difference how you mount it. Should work just as well upside down. Try it and see. Just make sure all the water is out when you winterize it.

This may be a simple view, but I would think vibration would be more difficult to mitigate in a vertical installation thus leading to a noisier pump

[dkottum]

Thinking about the noise and vibration it sends throughout the Airstream, one might consider mounting it suspended on heavy rubber bungees at four corners.

If you're talking about the typical Shure-Flo type pump, it'll work just fine either way. However, if you do mount it vertically, make sure the motor is above the pump, just in case something leaks. Later.

The vibration is a good point. I probably will mount on floor with some rubber I have around from a truck bed liner.

Thank you all

I think you will find that the motor does not have thrust bearings to support the vertical position of the shaft in the pump. While it may run for a while. I believe it will develop end play and eventually fail.

I'm agreeing with Twinkie on this one. We have some propane exhaust fans I use on my job that failed for the same reason. Mount them horizontal and they run for years. Mount them vertical, and you get about six months out of them, but they do run continuous... YMMV.

Read the directions when all else fails.

Floor would be best choice......consider the bushings on the armiture of the motor,the flat surface is the long portion of the bearing.....it should be on the floor otherwise the friction surface is riding on the wrong art of the shaft, one should
Keep this in mind with any electric motor....of course it will work in any position for a length of time.

My old Alfa had the pump, with the rubber feet, mounted horizontally on a 3/8" piece of plywood wall. This wall was flexible, more of a cover piece to finish off the storage compartment. One big sounding board, you could hear it throughout the rig.
Never failed though.

Thanks.

Will mount on floor
