We have recently had a house done up and moved in, but we have found that the water pressure it pretty low. We have twin boilers and a 300l Megaflo system but the pressure is not adequate for 1 shower let alone 4. We have had Thames Water come out but they claim it is the piping in the house and refuse to replace anything before the water meter as that would cost them quite a bit. A few friends have recommended getting a mains cold water pump to go where the pipe comes up into the house, but ones with tanks look pretty expensive. Plus I am worried that these would be quite noisy. Thoughts?
