On buying the taps i thought i had a combination hot / cold storage tank, which should work fine. (i live in a flat) but it turns out that i have a two part hot water storage tank and the cold water comes straight from the mains.

is there a way of installing a valve to stop the hot water backflowing?

will that cure the problem?

do i need to install a pump to increase the pressure of the hot water??

if any of the above could you please specify what equipment i would need and where would the new parts go.

please help!!!

thanks
