Background
If I understand correctly shower pumps have an internal flow switch on both hot and cold legs.
We recently had a gas boiler fitted and I retained our hot water tank (indirectly heated) so we have gravity fed hot water. So, we also have a large cold water tank that feeds the hot water.
We are in an 1890 Victorian Terrace and we share our cold water supply with 4 other houses, so our pressure is poor. It is insufficient for an electric shower, so I have a Triton pumped shower fed off a gravity feed (taken from the hot water header tank).
Therefore, upstairs I have an electric shower, bath cold tap, sink cold tap and a toilet cistern fed off a gravity feed.
The gravity fed hot water feeds all the house.
Question
I should like to install a power shower. I do not have room to put 2 x 22mm pipes (hot and cold) to the bathroom, neither do I have space for the pump in the bathroom.
So, my plan is to put the pump in the cupboard with the hot water tank and feed using 15mm into the existing pipework.
I will replace the bath taps with a mixer tap and thermostatic control.
This means that the pumped cold water will be feeding the bath, the bathroom sink and a toilet cistern. The hot would feed the entire house.
Is this a daft idea? Can the cistern take the pressure from the shower pump?
Of course if the pump fails, do I get nothing, or water as a gravity feed?
Cheers
