Hello everyone,

As part of a home improvement project I've installed a water pump to get more pressure on my hot and cold water. It works great but is rather noisy, producing a constant medium pitch whine when it is pushing water around to the taps/toilet cistern etc.

I was wondering if anyone has any tips on how to reduce the noise as much as possible?

I can't completely seal it away in a heavy box because it would eventually overheat so some amount of ventilation is required.

My first idea is to put it inside 2 layers of cardboard boxes with holes cut for the water/power/ventilation access and some kind of sound-absorbing material between the layers. I'm also planning to put in a thicker closet door and seal around the edges with some draft excluding tape.

Any suggestions on what would be a good material for the insulating layer?

Any better ideas generally?

All help much appreciated.
