High pressure taps on gravity fed water system??

[dignifiedwheat]

Hope someone can help with this newbie question... we recently just had a bathroom refurbished and we chose taps that recommend minimum 0.5bar pressure. We have a gravity fed water system so estimate we have 0.2 bar pressure. The taps run slowly and take about 15 minutes to run a hot bath. The basin taps also run slow. Both the bath and basin taps are mixers.

We have a shower which has a water pump to give adequate pressure at the shower head. My question is whether we could redo the plumbing so that all the taps are fed from the pump, instead of having the pump just feed to the shower. It's unlikely that anyone would be running more than 1 tap at a time, so in theory this would work but is it common practise to feed an entire bathroom off of a shower pump?

The alternative is (1) buy new low-pressure taps, or (2) convert to an unvented water system. But we can't find any low pressure taps we like, and converting the whole water system would be a huge job.

Any thoughts much appreciated!

Ideally you should change the pump to a whole house pump if your going to do the whole bathroom, your shower pump wont last long running seperate taps.

Thanks, I didn't know you could get a whole-house pump. Would you be able to tell me where I could get one? Can you post a link? I searched on screwfix but could only find shower pumps:

plenty of choice with pumps, just google whole house pumps, here is just one that came up.

Yeah get a Stuart turner monsoon pump. As opposed to their shower mate range these are designed for more than one outlet. The only problem with this is that your toilet will be pumped and it makes a hell of a noise when someone goes to the loo in the early hours. If you can run a separate non-pumped supply to your toilet then you're laughing. It's generally easy enough to convert to a whole house pump as you can place it near the hot water cylinder so you can pick up the hot water outlet straight from the cylinder and usually the cold water down service to the bathroom isn't far away. You'll need to link your shower back into the new pump though as you can't pump through a pump.

Its also a good idea to install a by-pass so that if the pump has to be removed for any reason, you can by-pass the pipework and still get water. If possible, change your toilet to mains feed.
