Can anyone recommend a good quality plumber in the Welwyn area of Herts ?

Maybe some more (hot off the press) information may help too. In another bathroom, we have just had a new bath fitted which is fed by the same HWC (unpumped). Flow rate with the old bath taps was fine, but hot water flow rate with new (monoblock) tap is awful - I guess it will take around 15...

OK, thanks - I'll talk to my plumber about this idea. What about fitting a non-return valve to the hot output pipe from the pump - would this stop air entering back into the pump from the shower ?

No they haven't - how do they work ? Surely if I have bled the system through and know there is no air in there and then the pump and the shower are both off - how can air be introduced into the system again ?

I have just had a new shower installed. It works fine when you want cold water (not often), but when you turn up the temperature to warm/hot, the pressure drops massively and it's like standing under a watering can. The shower is a Grohe thermostatic valve. The pump is a 3 bar twin impeller...
