Hi - please help if you can
A year ago I had a very old vented system replaced by a Worcester boiler and a non-megaflow unvented cylinder (I think its a Prostel). This has been fantastic - great shower in the main bathroom. Bath fills fast. Hot water at mains pressure/flow rate. Terrific.
A few months ago we had a loft conversion carried out and got the builders to install a simple Bathstore shower in the ensuite. No electric buttons etc, just a diverter valve to go to the rain head or the handheld shower attachment.

They took hot and cold pipes from the airing cupboard in the bathroom one floor down and routed these to the ensuite which is one floor up and about 4 metres along.
The issue is that the flow rate is disappointing in the new shower. it is quite a bit less than the main bathroom which surprises me as the height difference is not that great. I was expecting mains flow rate.
I have removed the two flow restrictors in each of the shower heads in the ensuite. This helped a bit but the two showers are very different in rate.
Secondly - if a bath is run downstairs and someone tries to have a shower upstairs, no water comes at all, in fact the pipes drain back I think because when the bath is complete and you try the taps upstairs again, you get all sorts of explosive ejection of air first!
Is there anything obvious I should check about this? Should the height make that much difference? Is this a known thing which simply cant be fixed? Are there any restrictors in the thermostatic valve panel itself?
Any suggestion would be much appreciated. Thanks!!
