    Hi,

    We have a shower waste pump located between joists, which is noisy when running, and also leaks. I posted about this on the plumbing board, but now I'm looking for advice on a better way to install it to try to reduce the noise which I think is at least partly caused by vibrations going through the joists and into the ceiling/walls below.

    The pump sits on a piece of plywood, which sits on two batons, each attached to a ceiling joist. See photo I have taken from below.

    We are having the pump serviced, and I am then planning on putting an anti-viration mat below it (i.e. between the pump and the plywood), but I am also wondering if the plywood can somehow be connected to the joists differently - e.g. using some kind of anti-vibration fixing. I have googled these and seen plenty of different looking options, but I am just not sure how I would use any of them in practice to achieve what I want to do.

    Does anyone have a link to a suitable product along with idiot-proof instructions on how I could do this?

    Cheers

    P.S. There is no suitable, practical, alternative location for this pump without major work which we are just not in a position to do just now.

    Most pumps come with rubber feet or a rubber mat to reduce vibration, you could put a couple of cheap mousemats under it.

    You have effectivly produced a 'sound board' so any noise generated by the pump is distributed through the joists.

    Shower pumps always appear quieter if mounted on a large concrete paving slab with a rubber layer under pump ans also where the slab sits on the structure of the building. So forming a rubber - concrete slab -rubber sandwich.

    Also use quality flexible pipes to the pump.

    Noise can be further reduced by covering pump in a solid, ventilated, box (upturned wooden box for example).
