Can I connect the basin supplies to the shower pump?

You have a pressure pump on the shower? Why not connect it to all the hot faucets?

Hi TC69

I'm afraid we don't use electric/power showers over here in the USA, so it would be unreasonable to comment on your question. I would contact the manufacturer of the unit in question and ask their tech. support department this question. My guess is that the answer will be no, not what the units are designed for, but I think it is an interesting question and would like to know what you find out when you do finally get a qualified answer!

Thanks!
