Replacement fresh water pump? (variable speed preferred)

[jmoultray]

We previously had a Shurflo extreme 5.7 fresh water pump in our 4788. I loved the pump--superbly quiet and worked great. It pumped into an accumulator tank and you truly didn't hear the thing 95% of the time it was running--only when using two or more plumbing fixtures at once could you hear it hum quietly.

Last year it died. We replaced with the shurflo replacement that is NOT a variable speed pump. It is VERY loud every time it cycles on.

Has anyone found a great freshwater pump that is QUIET? Variable speed preferred but primary objective is quiet operation.

Did you ever find a solution for this? I’m tiredness of our pump waking everyone aboard up in the morning when I’m up early. I’d love to find a quieter solution!

I my travel trailer pump was very loud. I quieted it considerably by adding a couple of looped, 3' long flexible hoses in between the pump inlet/outlet and the semi-rigid tubing. This isolated the pump's vibrations from the plumbing system and allowed the pump to move more freely on its rubber mounts.

That sounds like a low cost option to try, thanks!

I also once had that Shurflo pump and agree it was wonderfully quiet even without an accumulator tank. Now using a Jabsco 5.0 VFlo variable speed pump. The pump is also very very noisy and I've pretty much resigned myself to living with the pump noise. If I could find an available pump that was a) quiet b) didn't need a tank c) widely available, I'd switch in a heartbeat.

We have an X-caliber XRS series water pump operating with an accumulator, and it is virtually silent even when you stand over it. Water pressure is constant, and there are no screams if someone uses the Vacuflush when you are showering. They are available in 12 or 24V, and are not inexpensive, but worth every nickel.

Just like Norton Rider did, I added a flexible loop and it made a huge difference; inexpensive solution. See pic

I mounted my accumulator tank under the vanity, works great.

I just received a vFlo 5.0 that I am going to install. I am planning to try it first with accumulator tank, and then without if the install doesn't seem to work right. Jabsco recommends no accumulator but I see no reason to waste time removing it unless necessary. I'll report back after I get this project done, probably in a month or two when we are spending more time on the boat. When I saw the pump at the boat show it was very quiet, but quiet is relative in a crowded exhibition center vs. the dead of night on a boat.

Let us know how you like it once you get it installed!

I got the pump installed a couple weeks ago. I wound up removing the expansion tank due to hose length and wall space--I couldn't get the pump to fit onto the tank (different size mount) like the old pump, so I had to mount it on the wall. It requires being sideways which didn't match up terribly well with my lines without removing the expansion tank.

Overall, the pump works well and I don't miss the expansion tank. It is, however, still quite loud when working hard. I was hoping that it would start up slow, but it seems to wait for pressure to drop a ways and then run high power for about a second before slowing down. Our old water pump that was no longer manufactured by aqua king used to start nice and slow and was barely audible unless working really hard--this one is not quiet like that, but is FAR better than the loud obnoxious shurflo aqua king that we have been using the past year or so. No more hearing it turn on/off loudly, after the initial start it is pretty quiet for basic hand washing and showering, so that is a huge improvement, but it still cycles on loudly each time which is annoying when doing a load of dishes or laundry (the ventless dryer uses a 2.5 gallons per hour, enough that it cycles the pump on and off loudly every few minutes, just long enough to re-pressurize the lines--I was really hoping it would detect a slight drop in pressure and turn on low speed to build it back rather than starting powerful and then slowing down).

Overall, I give it a thumbs up as it is an improvement over what we had and I haven't found a reasonably priced alternative, but compared to my old shurflo extreme that is discontinued it is a resounding failure.

I purchased a back up from Walmart, same pump that is installed - although I suspect this installed pump is a replacement for the original. We have the accumulator tank. Hardly hear the pump running, even at high speed. For us the pump and accumulator tank works great. https://www.walmart.com/ip/Shurflo-A...-Pump/33276578

Next plumbing project is to add a two stage filtration system - particulate filter followed by carbon filter positioned right after the pump in the fwd engine mini room.

Did you add a flexible loop on the inlet and outlet, or just one side? If only one side, was it the outlet?

[Ahaua]

I only added the flexible loop on the outlet side.

On my travel trailer I added a loop to both ends. The idea is to isolate the pump from the plumbing and boat structure.

You guys do realize that I sell those pumps for a lower price than Walmart, and I ship the same day as you place the order

I didn't either!

Hey Kevin - Since you sell these pumps....I am on my third Shur-Flo pump in the last 18 months. It appears to be the pressure switch that is failing and I am now starting to get Shur-flo telling me that I should buy another brand of pump....any luck with other brands? I've got the Shurflo Marine Aqua King II 3.0 Fresh Water Pump #4138-111-E65 and at this point am tired of being down in the bilge with these things. Thoughts?

I really like the Jabsco pumps. I have a 6 GPH pump on the potable water system, and with the little OEM accumulator tank I do not notice any pulsing or pressure variation when in the shower.

That said i also have a Jabsco Constant Pressure pump 4.5 GPH as my watermaker boost pump and it has a lot of constant use hours on it.
