Sound proofing a water pump

Colm R

I have a pump in my attic that water for my hot and cold taps including the toilets. Its one without a vessel, so it just kicks in everytime you turn the tap.

It takes its feed from the storage tank and then splits into the cylinder and cold pipes.

I believe the pump itself is water cooled, therefore it does not need air to cool itself.

Could anyone recommend a material that would be best to sound proof it?
Some sort of lagging jacket perhaps. I know I won't get it completely sound proof but anything at all would be of help.

Cheers

Try get some rubber under the pumps feet. It will help reduce vibrations coming through to the building.
Regarding the sound insulation around, i dont know. A bit of googling will bring up a lot but its not the cheapest. If you have any rockwool lying around (haha yeah i know!) it would help bring down the noise.

Make sure you've flexible hoses coming out of the pump and that its not piped directly with copper

put a 20 litre or more pressure vessel on the system and then like others say put rubber under it

A domestic 200-300 euro pump water cooled.

I very much doubt it
throw up a picture or the model/make details

As it's in your attic, use rope to raise up by suspending it from the rafters, cheap and easy fix, I've done it several times.

Is there a noticeable difference? Would it make a difference in the likes of a hotpress for instance?

hmm any vibrations transmitted to the rafters ?

I've done them in both attic and hot press locations, you may still get some noise transmitted thru' the pipework, but there was marked improvement always.
As the nuisance is more noticeable at night, fitting a timer to the pump eliminates this.
When I installed pumped systems, wherever possible I put the toilets on gravity which eliminated pump noise at night as well.

Thanks guys for the opinions.

I'll get the make and mddel over the weekend to get confirmation that its water cooled. I should be able to slide some rubber underneath it.

I should have pushed for toilets to be on gravity in hindsight - too late for that now though.

Our pump in the attic has the exact same issue, it comes on for any dribble of water, except the main kitchen sink, even the downstairs toilet. The noise vibrations are bad and I'm sure it is not helping the electricity bill. I have a timer on it to turn off at night. Does anyone have a smarter not bank breaking solution so it will not come on for minimal use of water/downstairs?

If I turn off the pump at night, will water still flow to toilet and sink in bathroom? Might not get hot water in sink if pump is switched off?

Does the pump manufacturer specify pump should be on a solid level base? If so, I guess you'd be voiding your warranty by doing this.

You can get anti-vibration matts which will make a small difference https://www.amazon.co.uk/Stuart-Turner-Anti-Vibration-Mounting-Shower/dp/B00B9HZ0CG

You'll get a dribble, no pressure, no hot water alright of that's an issue.

I had a similar issue and just hung the pump from the rafters in the attic on some strapping....problem solved.

Depends on the plumbing. I switch mine off at night and still get gravity fed hot and cold. I can even have an early morning shower pump free if the family are asleep.

Sound. Must read up on warranty I guess. Expensive mats, this 25mm thinck one gets decent reviews https://www.amazon.co.uk/dp/B00QRXFEVE.


I read in another post about a plumber suspending the pump on a rope to avoid vibrations!
