Have just had a thermostatic bar shower installed and are very unhappy with the flow pressure. It connects to a combi-boiler and replaces a concentric model that performed much better.
The shower cost around £250 so we expect much more from it.
I rang the manufacturer ad they told me two things:
1. That there are new restrictions on water usage so new models won't be as powerful as older ones.
2. That bar showers are never as powerful as concentric ones due to the extra bit of pipe length (that narrows?).
So it would be good to know where the problem might lie before I contact the plumber and blame him for doing a lousy installation job!
Thanks for any assistance you can give.
