Noisy Water Pump
A new Artis Products water pump was installed on my coach when I bought it 5 years ago.
Its 4 rubber legs are mounted to a wooden board which is mounted to the coach frame rail. All the attachments are tight.
The pump motor is not noisy and delivers plenty of water pressure but when it runs it sounds like a jack hammer.
Any suggestions for finding and eliminating the source of the noise/vibration?
Thanks

Not sure how loud you're hearing but describing it as a jack-hammer doesn't sound good. Depending on the RV, mine have ranged from a soft purr, to a loud jack-hammer. I guess it depends on how its mounted and where. Either way, I personally tune it out as it's only temporary when water pressure is needed.
To answer your question, my money is on the pump itself as the source of the noise. If located in a small compartment maybe gluing sound proofing to the sides? If in a general compartment along side other stuff like water tanks, you might need to remove it from the plywood its anchored to and possibly look at bolting it in place by adding rubber feet or on a rubber base in order to absorb the vibration.

Try loosening up the mount bolts a little.....and make sure all the air is out of the system....

Three things: loosen the bolts and/or add more rubber mounting material; add/use flex faucet hoses between pump and OEM PEX water lines; add a small pressure tank....or maybe its just the pump itself???

Mine is exactly mounted as you discribed. One single change I did had an amazing effect. Instead of having the pex tubing directly going into the pump I placed a piece of flexible tubing in between. I was totally amazed by the difference it made. I was not able to hear the pump in the living quarters only if I had my head down in the compartment... cheap and very effective.

Thanks for the info. I'll try that.
Did you use off the shelf faucet lines or did you fabricate lines from flexible plastic tubing?

I used a piece of nylon reinforced white tubing that I had at the house. Because the discharge side of the pump has 55 psi you want to use a hose that holds it shape otherwise it will be difficult to seal onto any barbed fitting. Also I routed that hose in a nice loop coming off the pump to the original pex tubing. I was able to find all the fittings at Menards.

Pretty sure the PEX connections were 1/2 inch so it is easy to just reconnect with the faucet hoses from Lowes, etc--just add Teflon tape....also did the loop but maybe doing it on the horizontal is better to help with winterizing--not a biggie here in south Texas....

In addition to the flex hose inlet & outlet actually mounting the pump to 2 short pieces of tubing and mounting the tubing separately to the backing is very effective a noise reduction. See pic

My 04, the pump is mounted to a piece of plywood, the plywood was taped to the frame. The vibration harmonics travel through the entire structure. One day I noticed it wasn’t as noisy. The tape gave up and the board was hanging by the hoses. Been that way for several years now.
I think when the pump fails I’ll re-tape the plywood with some foam between the board and frame.

I had the same mount, I took a piece of pine and ran I from the piece of plywood to the basement floor, then mounted the pump to that piece of pine. A whole lot less noise, just had to turn upside down.

After witnessing the hold of the roofing sealant tape, DuraBond(?), it may be a good choice.

If I remember correctly, the tape was wrapped around the frame rail and board
before the floor was installed. Might have to find another way to attach?
