Water taps gravity fed or mains driven?

[jiffter]

Hi,
I'm replacing my water tank and hot water cylinder but i've noticed that my cold water taps are fed by the mains. I always thought all cold water taps except the kitchen tap were garavity fed from the water tank or am i wrong? Any guidance would be greatfully accepted.

your water tank(feed and expansion cistern) will only be feeding your boiler, you can have your bathroom taps off of the CWSC(cold water storage cistern) if you like, this would be a bigger tank and probably been taken away when the house was converted into mains, but your heating system requires the F&E tank as it is a gravity system.

There was never any stipulation that cold water taps had to be fed by cold mains or by the CWS tank, but if most were fed by the CWS tank, the kitchen tap had to be on cold mains for drinking purposes. This was an age old thing tho & most houses for the last 40 odd years have most cold outlets on cold mains unless its mixer outlets where the pressures have to be balanced.

Many thanks for the advice, i'll stick with the mains cold supply i think.

Bear in mind that mixer taps and mixer showers have troubles with a cold mains supply as the cold is too powerful to balance with the hot. If all's working fine then there's no need to change anything but if you decide on mixer taps/showers in the future some pipework might need altering.
