Reducing noise/vibration from a shower pump

[SonicHedgeHog]

Our shower pump is going to be changed for a Stuart Turner pump next month as part of a new bathroom. Currently the old pump sits in the airing cupboard on a piece of MDF raised off the floor of the cupboard by four small legs made of copper tubing. This looks quite nice, but by golly does it make a racket. So, the new pump needs to be quieter. The Stuart Turner is a much higher quality pump and so should be quieter from the outset. Stuart turner also sell an Anti-Vibration / Noise Reducing Pump Mounting Pad which I intend to mount the pump on. Does anyone have any other clever ideas about how to reduce the noise and vibration from our new pump?

That anti vibration pad will help, and I bet it alone gets you 80% of the way there.

You could try boxing it in, with a thick rubber mating on the inside of said box, if there is space?

Got any pictures of where it is going?

The pump may get warm so I'd check that boxing it in won't cause other problems.

I'd just see how it goes with what you've ordered first...

Good point! Mine gets very hot through pumping the central heating.

+1 on waiting until it is installed. I bet it is already set up well enough for you to not need to bother with anything.

When you fix it down, fix it to the stiffest thing you can. That MDF sheet will be very soft, letting the pump put alot of energy into the structure. Bolt it to a floor joist or the bottom of a block wall (not the middle!), using rubber bobbins under the feet if you have a problem.

Thanks chaps. I'll tell the plumber to secure it well to the floor of the cupboard in top of the vibration pad. Will report back if I need to.

This sounds like a good idea, thinking of making a frame/support from angle iron and using some bobbins.
