I've just had a new shower installed. The spray from the old one wasn't power shower quality but it was sufficient. Thames Water says pressure is 2 bar, litres per minute are 24 from water meter but just 10 lpm where it enters the bungalow (perhaps due to furred lead piping). And with it being a bungalow there's less of a drop. But still, there was a reasonable spray coming out of the old shower and there is really nothing more than a light trickle from the new one. The bathroom taps are more powerful than the shower. I'm going to raise this with the firm who installed it but I wonder if anyone can suggest why the old one was ok and the new one definitely isn't. And what's best to do.
