The Water Pump Is SO Loud!

I just installed a Jabsco Par Max 2 under my port settee. It has the rubber feet but still vibrates alot and makes too much noise. The only good thing is that it keeps us from using too much water.

Any helpful hints or ideas about how to quiet this thing? Or recommend a quieter fresh water pump (price range $150 or less)? Then I would just use the Par Max 2 as a back up while cruising.

Thanks,

Interesting that the advertisement reads..

Self-Priming
Run Dry
Super Quiet
Smooth Flow
Low Current Draw
Extra Low Profile
Easy to Install

If its suposed to be super quiet I woulsd take it back.

If you don't already have one, get a footpump. Only use the pressure system when you absolutely have to, which may be never. With a foot pump, your water will lat 2-3 times longer without much sacrifice in convenience.

What do you have it mounted on? If it is a plywood board or FRP platform it might be like mounting it on a drum skin if you know what I mean A good solid mounting will go a long way to reducing noise. Those pumps are normally fairly quite, if it is new and the pump itself is noisy you might want to exchange it, it could have a defect. Try un-mounting it and place it on a foam pad and see how it is. If quite then you know it is the mounting.

Good luck

Get a Flojet (not a SureFlo). Several models for FW pump, some with variable motor speed and accumulator tank separate. On a smallish boat you probably don't need these. The simple, all-in-one pump works great. Been using them for 15 years on two boats, after I tried every pump on the planet while I was a liveaboard.

ITT recently bought them, and jacked up the prices, but they're still a good bargain compared to all the junk out there.

Here's a link: http://www.nextag.com/flojet-pump/search-html
Looks like Hodges Marine has the 3.5gpm pump for $85. Good price.

I agree with Wayne...also have a look at how the screws and rubber feet are installed...some times the screws are so tight they contact the plastic of the base.

I had the same problem with my 2 pumps. I got 1/4"thick, fabric-re-inforced, flange gasket rubber, 1" larger than the pump footprint. Mounted the pumps on this with bolts, and then mounted the rubber up off the locker floor with spacers. No more noise.

Is the water supply free flowing. Maybe check if there is a filter that is blocking the flow and making the water pump work harder then it needs to.

wrong pump

that pump is always going to be loud, even if better isolated. if quiet is what you really want, switch to a variable speed pump, such as the Jabsco Sensor Max VSD. Of course, this will cost twice as much as the pump you just installed.

Another idea is to buy a pressure reservoir so the pump does not cycle as often.

Jabsco is notorious for being noisy no matter what they advertise. As others have mentioned, cushion the mount as much as possible and look at the location. If it is in an area the will reverberate the sound, that is adding to your problem so you might need to move it or soundproof the area, or buy a quieter pump. WG
