Reduce sound from water pump - does this work?

Linto

My builder and plumber tried this out to reduce some of the sound from the pump. Any thoughts on this set up? Can I apply any further tweaks to improve even more.
Its not bad but its still pretty loud.

Replace the copper pipes with flexables, suspend the pump on some rope, this should eliminate a lot of the noise.

I wouldn't bother suspending I just make a ply base and bit of carpet. And plastic pipe too

you could put pump on time clock have it off at night ect on during day .. you could try a rubber matt it helps if you wanted you could change pump for submersible pump which goes into storage tank

Have you got 2 spare floor tiles big enough to sit the pump on and some silicone caulk?

My pump already had flexible hosing and the little rubber boots for the feet but still made a terrible racket audible throughout the house.

I took 2 spare kitchen floor tiles and gave them a good squirt of caulk on the undersides. Placed the first in position with the second tile on top and then the pump on top of that. The combination of the mass of the tiles and the vibration isolation between pump->Tile->Tile->Plywood subfloor means that most of the vibrational energy is converted to heat instead of sound. The tiles get quite warm when the pump is on.

Can't hear the pump in the rest of the house anymore, barely audible in the bedroom underneath and audible but not annoying in the attic bedroom right beside the boiler closet.
