Hi, the water pressure and rate of flow at our place is a bit marginal. On the water main is an ageing stopcock. As I understand, stopcocks are not full-bore, so they reduce the flow a bit. Any problem with replacing the internal stopcock with a full-bore, quarter- turn isolation valve? Eg
I can turn everything off in the street thanks to Thames Water having just replaced the seized-up old victorian stopcock there with a shiny new water meter.
Cheers!
