Hi
there are 2 aqualisa power showers in the house we moved into. The motor
units are in the loft mounted on hardboard screwed across the rafters.
This obviously generates quite a bit of noise in the mornings when
either shower is used. Whats the best way to rdeuce the noise from these
units?
Thanks

The noise is coming through the ceiling because the pumps are directly
connected to the rafters. You need to find a way of mounting them with
very springy rubber mounts. Sorry, I don't know of any :-(
Perhaps others do.

Perhaps you could mount them on wires from the roof, or on springs on
the joists.

You will also have to fit flexible pipes to the input and output as
well. Otherwise they will fracture over time. It must be doable.
