Can you help please I have fitted a high presser tap with a spray in my kitchen also a high presser tap in one of the bedrooms and the presser of the hot water is not enough for the taps to work eficently, (the cold is fine as from the mains) although the other taps in the house are fine, I have in mind to fit a pump in the loft to boost all the hot water system. I do have a pump to a power shower which works well. What sort of pump do I need, I wanted something that is quiet, as it would be a pain if every time the tap was turned on you could hear the pump start up. Thanks.
