Single shower pump for hot water

[bobsywobsy]

Hi

I have a mixer shower run off a gravity fed system, but the cold is run off the mains. Pressure for a hot shower is pretty dire, so I am going to install a single shower pump just for the hot water, as the cold is fine.

It's only a small house and there is only a kitchen sink and a bathroom sink as well as the shower. I was wondering rather than running new pipework to feed only the shower, I could just tee into the hot water to feed the other 2 sinks as well as the shower. The sink and shower are never used at the same time so enough water will be provided for the pump to work properly. Plus I will get better pressure through my taps too!

Just wondering if this is possible, and won't cause complications.

Thanks
James

Its not ideal, but can be done.

ahh I see, thanks for the link. Though I see it mentioned about there possibly being a problem if the hot and cold pressures aren't matched. Would this mean I would have to buy a pump that has roughly the same pressure as the mains? That would be a pretty powerful shower! Or maybe getting say a 1.5bar pressure pump and whacking a pressure reducing valve before the cold inlet to the shower?

Thanks
