Habitation water pump noise

Hi everyone, does anyone suffer the same problem as me? When I run the water to wash up, fill a kettle etc, I can hear the water pump working. Does anyone know how to silence the pump?
Another strange thing is, that occasionally in the night it suddenly bursts into life for about 5 second for no reason. Any thoughts?
cheers

All pumps will make a vibration sounding noise, they should be mounted on rubber feet to minimise this, you can also get an accumulator to make it work less often, but the night running is best to turn it off, and open a tap briefly to reduce the pressure.

In theory, it should not restart until you open something, so check for small leaks just in case. It might be leaking back into the tank, which isn't so much of a problem.

We've had pumps in various houses for water supply from wells and they all made a noise. The one in the van is the same. Recently it seemed to get noisier with hammering in the pipework. On investigation the in-line filter at the pump was clogged with gunge. After a clean it was much better, but still makes a noise and very occasionally starts briefly for no apparent reason - sometimes when a door is slammed. No leaks that I know of. Perhaps the pressure needs topping up so it fires off.

Thanks for your message, I’ll check it out.

Thanks for your reply, I’ll check out for leaks but I haven’t noticed any loss of water. Cheers

Thank you for your reply. i hadn’t thought of filter blockage, I’ll check out the filters. Cheers

Ours makes the odd fart noise (as we call it) where it runs for a fraction of a second. I looked into this a while ago and the suggested solution was to fit a John Guest non return valve into the system to stop water draining back.

I never got around to doing it in our last MH and tbh I'll just live with it in this one unless it becomes worse. It certainly doesn't last for 5 seconds though so worth investigating I'd say.

I'm perfectly happy to have a bit of noise from the pump; it means that I become aware if it's operating when it shouldn't be.

Ours does too sometimes in the early hours. I have always assumed this is due to the stored hot water cooling overnight causing the pressure to drop slightly. I suppose an accumulator would sort this but TBH it's not really a problem for us.

No14 - that sounds like a good call. Ours does it more at night too. The water is usually hot to wash up around 6-ish then switched off...and a few hours later it starts making farts.

Good shout, cheers.

Ours makes the occasional burp too. I hadn't twigged the connection between my constantly varying the van's water temperature depending on need, and your suggested reason.

I'll check, but I bet you're right. Thank you! :) (y)

We only turn ours on when we need water now, 2 floods in 11 years one while we were driving down to Spain left us with a lake between the flooring and the bottom of the van..great for the sauna effect in 35 degree's..not a good sleep that night 🙄 and recently burnt out a pump..seemed to have a bit of air in the system that for some unknown reason it couldn't shift but it was just humming rather then the usual klonks so went undetected

It seems to me that you are asking two questions. One is how to make the water pump quieter, and the other is how to stop it running when it shouldn't.

To answer the second first:
1. Make sure that there are no leaks in the system. that might be a leaking tap valve, a weeping joint or a failing non-return valve near the pump.
2. Adjust the pressure switch to a slightly lower pressure so the pump is on top of the job. However, if your battery voltage drops, this enfeebles the pump, so check the voltage when you adjust the pressure valve.

And to answer the first:
1. If the pump is an in-line one on a rubber bracket, make sure it isn't screwed down too tightly. Sometimes they're so tight that the rubber mounts are crushed flat. Check that the rubber brackets haven't hardened with age. If it is not on rubber mounts, make it so. Also make sure nothing else is touching the pump or pipes near it.
2. If the pump is a submerged one, try to arrange it so that it dangles from the pipe without /quite/ touching the bottom of the tank.

Remember if any of your plumbing is house style push fit, they seal better with pressure. Depressurising the system could cause it to drip.

Hi there, thanks for your reply, I love saunas but not on the move.🤪 The air part of your message is something for me to consider, so I’ll check it out, thanks.
I don’t have a problem with the pump, but it’s situated under my wife’s bed, head end, so I need to find ways to solve the issue. Thanks again. 😁

Hi there, thank you for your reply. Certainly worth checking out your ideas, thank you

Pressure-sensitive switch under the pillow, to turn off the pump when there's the weight of a head on the pillow? ;)

We had a Shurflo pump in our Swift that would akso run for a split second every now and then. I checked for leaks, none, checked it with water heater on and off, no difference, then stripped the pump down to check for any internal leaks, again, nothing wrong that I could see. Then, one day ( while watching the Tour de France) I went into the van to get something and noticed a burning smell. After a good look around, I found the water pump was red hot, so quickly disconnected the wiring to it.
A few days later, I fitted a new pump. No more pump chattering.
