I'm looking for suggestions to deal with an extremely noisy water pump. I've recently bought a top floor apartment and the water pump is in an airing cupboard as is my cold water tank - it looks like the builders of the apartment should have put the tank in the attic but possibly the tank arrived too late and the attic hatch was finished at that stage. Every time I turn on a tap etc the pump is needed - without the pump turned on the water pressure is a trickle. The manufacturer of the pump is Stuart Turner Ltd, the model is ST55 (I think) and most likely this was put in by the builders about 8 years ago and is probably a cheap model. I don't think putting bubble wrap or anything like that to insulate it will work as it's so noisy. If I replace the pump do people think that it would be much quieter and what pump would be best? The pump/water tank is beside a bedroom so the pump/water inflow would have to be very quiet. Alternatively, I'll be getting an attic stairs put in which means I'll be making my attic hatch larger so I might be able to get the water tank moved to the attic - my neighbour has his water tank in the attic and he has no need of a pump. Which of these options seems best?
Thanks in advance.
