If when you turn the stop cock off all the taps immediately stop, they are likely to be mains fed.

The cold tank will probably just feed the hot water cylinder and possibly (not necessarily) the toilets.

For a power shower you would need a cold feed from the loft tank and the hot from the hot cylinder so that the pressures are matched into the pump.
