I have just had a bath removed and a shower installed and had to have a pump installed to give me a decent shower. We have a low pressure hotwater tank system (according to plumber) and we needed the pump to power the bar mixer shower. Every time I turn on the shower there is a large hummmm from the pump.
Is there anything that could help reduce the noise?
just as an extra. any mechanical device makes noise but the amount of noise it makes is also dependant on how and what it is mounted on. if the pump is mounted on a joist or wooden floor it might well amplify the noise. you could only find this out by mounting the pump on a vibration absorbing material
