Hi, I'm having a new bathroom installed and would like to know the best way to get the most pressure to the bath/shower taps. I have a Potterton Performa 28 Combi boiler. At the moment, water pressure in the bathroom isn't that great. Would a thermostatic mixer be able to cope with cold water direct from the mains and the hot from the boiler or will the pressures be too different? At the moment I believe the cold is coming through the boiler too (if I turn on the hot tap the flow of the cold is decreaed).
