Hi I've just had both my bathroom mixer taps fitted (screw down valves not ceramic). They are both connected to the mains cold, but they already seem to be dripping a bit and when you turn the cold on the bath it makes a popping sound. Should a pressure limiting valve should be fitted to each tap or the main stop c*ck be turned off a bit or is high pressure not the cause? The hot on the mixers is gravity fed.
Thanks
Martin
