Water pump sounds a bit loud in the wee hours of the morning. I have been on the net enquiring about this problem, and the maker claims the Shurflo 4009 is the quietest pump ever, some have posted on the net various ways of getting the noise down, from softer hoses, extra rubber mountings to even suspending the pump on wire. I am skeptical that these ideas really will work well, and think its part of the design of the pump and its rotor.
Have any on here done any work to quieten the pump down, and has it been worth while.
For instance it may need to be mounted in a sound proof enclosure to really make a difference.
I have dismounted the pump off the floor, and sandwiched foam between the feet and floor, held the pump at various angles, but no real effect.

I have mounted pump on a pad of rubber, rubber screwed to floor, pump screwed to rubber then insulated the plumbing where it touches the floor/walls as a lot of sound is transmitted by the plumbing with the floor acting as a sound board, only need to do this for a few feet from pump.........hardly hear the thing now, folks have lots of ideas but hardly anyone thinks of sound travels thru water.

Maybe some foam under the rubber might assist as well. Might even do mine when I get the HWS changed over.

Big Mal, are you saying that no matter what I do, there will always be some noise transmitted through the water?
Dougwe, I tried putting foam under the feet, the difference in sound was negligible. I'm deaf, its her that's hearing all this.
The pump itself comes on a rubber mount. I just have my doubts about being able to reduce the noise on this pump.

Hi Ian
Maybe an silly idea, but maybe I'm lucky I sleep the whole night without waking up nine out of ten nights
Why don't you turn it off at night just before you go to bed and turn it back on in the morning again
Regards John

If you have rigid pipe connecting the pump that will transmit the vibrations to where the pipes are secured to the floor/wall. The panel the pipes are secured to will in turn act as a sounding board. That is the reason for using hose with a loop to connect the pump to the plumbing. The hose loops are reputed to isolate the pump from the sound board. (I have no experience with pumps in vans but I have a fair engineering experience and am repeating what has been posted in the forums over the years.)

I like Johns idea - just turn it off when you go to bed at night. If you have an inbuilt loo of course you will need to turn the pump on, but I guess everyone will be woken up with the one needing to use it. Fill up the kettle at night if one of you gets up earlier than the other to have a cuppa.

Ditto to Bruce and Bev post above
I turn it off, and only turn it on when we are awake inside the vehicle
My theory is, that if a hose should burst, while you are sleeping, we could wake up to no water in the tank

Hello Tony, where have you been! What you and others have posted is what the pump instructions also advise. I guess too that this is one reason for getting a loo with a header tank. Yeah wouldn't it be wonderful to be able to sleep all night.

Hello Ian
You do not need a loo with a header tank, as it takes all of two seconds to switch the water pump on
The other week, the boss put her hand around the door to grab her ciggy ashtray
She accidentally touched the sink water tap, we lost a bit of water, if we had been out and about for any length of time, we could have lost all our water
I have been traveling up the west coast, and am now in Darwin, but leaving tomorrow for parts unknown
