Is there a quiet water pump?

Hello everyone,

I have 2016 have a Fuzion 414 that has, IMHO, a loud water pump. I was curious if anyone knows of a QUIET replacement for the stock water pump?

Thank you

Lisa

Lisa,

They're all quiet. Just push the pump switch until the red light goes out. It's that darn red light, not the pump that makes all the noise....

That said, simple answer to your question is, "Nope".....

Some are less noisy than others but they all make noise and it's usually not the pump but the vibration set up by the PEX lines rubbing against the trailer structure, sometimes many feet from the pump.

Get in there, isolate the pump from the floor ( rubber pad under it). Find all the water lines that are vibrating against floors, walls and each other, relocate, insulate with pipe insulation, tie wrap to reduce noisy vibrations.
Well worth the work, I barely hear mine now.

The OEM Flojet in my coach was disturbingly loud at night. I purchased a Shurflo replacement and it was noticeable quieter, before I added rubber padding and insulated the cabinet its housed in with foam. I also added a "quieting kit" to the Shurflo which helped reduced vibration from the pex water lines. Now its whisper quiet at night. Kids use the toilet without waking us up. A worthy upgrade. Here's the mod in more detail:

I invested heavily in... Pool noodles, $5 , cut them length wise and judiciously positioned them along lines coming from the pump close to, well, everything they touched. Used long tie wraps to secure them.

Boom it's much quieter now. Wife is happy.

I isolated the pump from the pex lines by using braided lines between them. I also installed an accumulator tank inline so the water pump does stay on as long. I then foam lined the cabinet to help contain the noise too.

This. Especially for the late night toilet trips when the pump is next to the wife sleeping. Being able to leave the pump off and still flush 2-3 times a night has been a blessing.

Opened the panel covering the water pump (basement left side on a Montana 3130re).
I cut up some left over rubber shelf liner (Walmart) folded up to 1/2" thick to make isolation buffers.
Removed the pump mounting screws and installed the buffers under each screw and the head of the pump (to keep it from vibrating against the floor). I also installed 1/2" foam pipe insulation everywhere a pipe touched a wall or floor. I tested the pump noise, it was greatly reduced. I noticed the pipes mounted on the control panel inside wall were still reverberating noise up through the wall. I insulated them using more rubber shelf liner. Again a great reduction in pump noise. I closed up the wall and tested again from inside the RV. The pump (original flojet) now only has a slight hum.

Somewhat unconventional, but on our new Jayco FW, the water pump is not anchored to anything. It is not even close to the floor to suggest the screws were missed during assembly. It is held up off the floor a few inches by the PEX lines.

It is a Surflo Revolution, the same as I had in my previous Passport, but noticeably quitter than I was able to achieve with isolation mounting and cavity insulation on the Passport.

The accumulator tank is a must for late night bathroom visits.

I made a sound insulation platform to mount my pump on. I used a 3/4" foam mat and two pieces of 1/4" plywood. It isolates the pump vibration from the floor and with the soft hose pump attachments and "foam noodle wraps" where the PEX touches anything solid, our pump is significantly less noisy than before the mods.

I installed a piece of foam knee pad under each leg of the pump, and added a loop of braided tubing on the inlet and outlet. I also slightly relocated the pex lines under the kitchen sink to keep them from banging against the cabinetry. Very quiet now!

I think the noise can be a blessing. It has made me aware that there was a small leak somewhere so I could investigate before it became a larger issue.

Every trailer I have owned over the years has had either noisy pumps or pipes, or both. The RV I own now I do not hear the pump or the pipes. Perhaps the manufacturer has listened to the customers?

I have to second Slow’s recommendation of the Sureflo Revolution 4008. It’s not silent but is much quieter than most of the OEM pumps I’ve experienced. I replaced it with the 4gpm jackhammer inspired model they put on my current RV.

It also has a low volume bypass which can reduce the need for an accumulator tank to stop some of the low-flow rate cycling, meaning it runs a when there’s demand,but low flow rate, so you don’t get the pulsing in the water (and potentially being frozen/scalded in some circumstances in the shower) as the pump turns on and off.

+1 on the pool noodles. I got deep into the basement and went crazy with the pool noodles including under the pump. Works like a champ and cheap!

No one had replied to this thread for a couple years... the guy who posted prior to your post made a strange post about his apartment bathroom. Not sure what that was about and it was that person's first post.

My snoring is so significant that water pump noise at night isn’t an issue…😺
