Quieter water pump - recommendations 23fb

[bonginator]

We have the factory Shurflo water pump on ou '08 23FB. It is pretty loud and we are early risers so I hate waking every other site for miles when we use it.

Do you have some recommendations for a quality quiet replacement pump that can run and operate if it goes dry?

Looking for real use recommendations if possible...

Thanks!

The pump is mounted to bare flooring which acts as a sounding board when the pump goes on.
Try quieting it down by mounting it on rubber grommets.
There are other pumps but all operate using the same basic diaphram design. Using another pump would likely require plumbing modification.

I built a platform using 4 of these...

Same pump .... same complaint! I mounted it on rubber which did help, but only a little bit. My next attempt will be a flexible output line which I have read helps by not transmitting the vibrations through the plumbing. I look forward to other suggestions.

Where can you get the these rubber stand offs? How do they attach to the the floor? Do you need to build a platform and then drill holes and use blind nuts for the rubber standoffs? Then screw the platform down and install the pump on the standoffs with nuts?

Does the existing plumbing line up with the pump when it's raised from the original position?

Thanks

Thanks Bob, I like the idea of the rubber mounts and may use it as well. I put in a small water pressure accumulator from camping world which absorbs some of the pressure variations as the pump turns, and gives a little bit of reserve pressure so it doesn't run with every movement of a faucet.

Do you have a link to the product? Sounds interesting...

I'm considering a variable flow pump.

Here's a thread on the accumulator

Thanks!

The rubber stand-offs should help... You can also wrap pipes in foam rubber if they are knocking against surrounding materials (which can happen at other points than at the pump)...anything to reduce vibration will help make the pump run quieter...

Also, you should avoid running the pump dry. That will allow air to enter the line which will create other problems ...

Actually they came from the "junk" drawer of my tool box.
Bosch electric fuel pump mounts.

They looked exactly like these....


If I had it to do over I would use these....no platform needed.





Helpful?

Anyone actually install this? Seems like it would address the noise issue...

I guess I am not the only person who is bugged by the noise!

Just ordered three as recommended by Bob above, about $9 ea. and small shipping charge, easy to use website order system. We'll see how they work.

does the pump line up ok using them? or are there other adjustments to be made?

Installed a Shurflo Revolution pump it took about 15 mins and less than $100.Much quieter pump with more pressure .Big improvement with no more loud knocking.You can hardly hear it run.

Most RV pump companies do not recommend using a accumulator.

Old Pump Recycled:I attached the old pump to a small piece of wood and added alligator clips then bought 12 ft of clear plastic hose and cut it in half and attached it to inlet and outlet of pump.I now carry it with me along with a portable jump box and use it to fill my fresh water tank from 10 gallon jugs when not connected to city water.Much easier than trying to hold 10 gallon water jugs when filling tank.Also much faster.

$9 each, wow. What size do you purchase? My 55 Aquajet has 4 feet.

I'm going to check Elliott's Hardware in Plano, TX for something similar. They have a ton of specialized parts.

What is the specs on the Shurflo Revolution pump compared with the 55 Aquajet. I think the Aquajet is 5.5gal/min. However, it doesn't seem that powerful as it doesn't fill the toilet bowl faster than my previous Casita and it seems to be the same toilet.

I got the number xxx20, the small ones. Seems to be all we will need. More news when I get them installed. We live in rural Virginia, so shopping on line at whatever price is most always the most economical way to go for us. <grin>

Seems quiet, especially when fully open.

Might be working looking at. I wonder how much re-plumbing would be needed.

15 min to swap out.
