Noisy water pump

Noisy water pump Empty Noisy water pump

Hello
Our motorhome's water pump makes a rumbling noise when it is being used. Is this normal or something we should be having checked?
Many thanks,
Liz

Has it been disturbed recently, if so maybe it's mounting screws have been overtightened, try slackening them off. Too tight will cause vibrations through the body.

Assuming it's a Shurflo, is it mounted on a vertical panel in the space under the wardrobe floor? (Some advice from A/S if that is so.)

If it is, Paul's suggestion may well reduce the noise, but when I had one fitted a little while ago, Mark (at the Service Centre) advised against fitting it there as they always tend to be noisy, turning the panel into a sound board. Ours is fitted to the floor under one of the bench seats, and although it can still be heard it's by no means intrusive.

I wouldn't bother to move it unless it's really annoying you, but it wouldn't be very difficult if you wanted to.

Hi Liz
Noise from a pump is normal. The question really is whether your pump generates more noise than 'normal', and this is not something that can be established through the written word.
You should ask other motorhomers to allow you to listen to their pump(s), or ask them to listen to yours and offer an opinion.

It well may that there is air in the system this trend to make pumps noisy try running the pump for a longer spell fitting an accumulator tends to cut down on pump noise..

True enough Alf, but Liz hasn't told us what type of pump they have, or whether the noise has recently become much louder.

Both these questions are fairly crucial before we can offer worthwhile advice.

Your point about air in the system is spot on, but again much depends on the type of pump. The submersibles can make an awful clatter when they are pumping air, and after a drain down this can last for an alarmingly long time.

Shurflos tend not to be much, if any noisier when they are pumping air because they work with a diaphragm rather than an impeller. They rarely seem to have problems with air locks either, which is more than can be said for the cheap and nasty little impeller pumps.

My Shurflo made an awful noise once and it was because I hadn't refitted the in-line gauze filter properly so it was sucking in air as well as water from the tank.  Our pump seems louder in the bathroom than elsewhere due I think to the pipes and plastic mouldings resonating but its not a problem.  I fitted pipe insulation to some of the pipes which reduced it.

Noisy water pump Empty Cure for noisy Shurflo pump

Post by Petesymphony Sat May 22, 2021 6:10 pm

I cured this on my Inca, (Shurflo mounted under wardrobe floor on bathroom wall) the wall does act as a sounding board. I cured mine by glueing a piece of polyurethene packing to wall, then glue a piece of ply to 
packing and then mount pump onto this ply sheet. The advantage of this modification is that the pump pipes etc do not have to be disturbed, I found it a very effective cure.
The poly packing is about 1/2" thick and is often used by manufacturers to pack goods.
