I simply removed the hold down crews on our '89. But it had lots of clearance for hoses etc. New one came with gobs of foam packing to keep the hoses away from the adjacent plywood.

Pump silencer

Being retired from the plumbing trade for 45 years, I found that the pump on my 2007 airstream Safari was very noisy. I relocated the pump so that it was easier to work on and mounted it on 1/2 inch foam and firmly attached it to the floor. Then I installed stainless steel braided hoses on the inlet and outlet sides of the pump. I also installed a water hammer arrester on the outlet side of the pump. You can purchase these from any plumbing supply house. Use 1/2 inch size. Anywhere the pex piping touched adjacent pipes or cabinet interiors I installed foam pipe insulation around the pipes. Now I am not sure that my pump is even running when I turn it on. This is what worked for me. PS I hate noisy plumbing, can you tell?

Thanks for this.
When you say "stainless steel braided hoses" are you talking about the stuff one would normally see under a sink. That connects the tap set to the water line? Also what is a hammer arrestor?
Sorry for the questions as it will let you know how much I know about plumbing.....lol
Thanks

Doug

Edit - just did a Google search on Hammer Arrestor and it looks like something I've never seen before, but should not be hard to install as long as I can find one. Thanks

I'd like to relocate mine. The literature says the fittings are 1/2"-14 NPSM. I've read these are different from NPT. Will I be able to find longer hoses?

I think two loops of the braided vinyl hoses do a better job of isolating the vibration. But, they do require a barb fitting, that some might object to. However, mine have not leaked in 16 years.

Noisy water pump I've decided even though it isn't broken I'm gonna fix it

Spent $100 on a Shur Flo Revolution took 10 mins to install.No more cheap noisy knocking pump.Been 3 years and still enjoy the quiet and more water pressure.One of the better upgrades that you can do.

Now I use cheap noisy pump when boon docking to refill fresh water tank,attached a hose to inlet and outlet then installed some alligator clips on wiring.I carry a jump box that powers it when needed.

My pump was 1/2 in MIP threads on both inlet and outlet. If you buy 12 in long x 3/8 in braided hoses with 1/2 in FIP connectors on both ends and use a small brass Nipple to make the Conection from the pex and the hose connection. These hoses can be purchased at any Lowes or Home Depot plumbing department.

Yes, these stainless steel connectors are used to hook up lavatories and water closets. They come in an assortment of lengths. Most range between 12 - 18 in and are 3/8 in ID. You will most likely need 1/2 in FIP connectors on each end to make the pump to pex connection. This may vary depending on how your plumbing was installed.

Has anyone installed the Flojet VFLO, variable frequency drive pump? VFD's are supposed to pump only according to the flow, rather than start at full speed, then shut off. Its expensive but uses less volt/amps for smaller volumes, and supposed to be very quiet. I'm a believer that you get what you pay for, but cautious of claims, and relying on user experience.

Have Shur-flo Whisper King in both trailers with hose loop on the output side. Both over ten years old and both quiet. Just make sure the output hose is not laying against anything or there may still be noise. The loop is important.

Flojet VSD pump

Re: #23 - We’ve been using the Flojet VSD pump for about 2 years. We love the VSD pump. The VSD water pump is really quiet – just a whisper at start up and on low demand. Now we can turn the pump on in the middle of the night, flush the toilet, and the pump noise doesn’t wake up anyone in the trailer. I dare say the old pump may have woken up our neighbors it was so loud. Hardest thing with the new pump is that it is so quiet I don’t think about it, and it is hard for me to remember to turn it off for travel, etc.

When I bought the Flojet VSD pump it was $194 from CW. It came with a strainer and a bunch of adapters to use for the install. The strainer is 40 mesh screen same as my old one, but the new one is much larger. My old strainer was in the waterline about 10 inches away from the pump. The new strainer plugs right into the input port on the pump, and that is how I set it up and I just took the old strainer out of the system.

Good luck with your decision!

I like the suggestion of braided segments on both sides, and pipe insulation around the individual lines.. That might work. There has GOT to be a solution.
There is!

Buy a new pump. The Shur-flo Revolution is much much quieter. I can still hear it but is more comparable to a light hum rather than the jack hammer sound of the original pump.

I forgot to mention an additional plumbing trick I added while I had the pump disconnected. On the inlet side of the pump I installed 1/2 in FIP full port diverter ball valve. One side connects to the pipe going to the fresh water. The other side I installed a FIP to hose connector so it allowed me an opening by switching the valve once a year to fill my pipes with antifreeze. This makes it very easy to do that chore by just hooking a small hose to the valve opening put it in a gallon of antifreeze and turn on the pump, open each faucet until you see the color of antifreeze. Usually only takes a gallon of th antifreeze to do my job. Then I close the valve back to its original fresh water position and screw a hose cap on the open end of the diverter valve and I am done. When spring comes just add water to the fresh water tank and pump all the antifreeze out.
