the water pressure on my incoming main is pretty much immense..would it be a wise move to get a prv fitted to maximise the pressure at 3bar..would this prevent hammer down the central heating pipes as ive read about on this forum..the basin/sink cold taps also splash out of the sink if tap turned on 2 much..although there is bollofix valves fitted local..maybe adjust them ? the water pressure on my new mira exell shower at present is sufficient but not great.. as i have a vokera linea 24 combi boiler my heating engineer said the pressure at present is all that this smaller boiler can pump to the shower..if i installed a prv would this pressure to the bathroom shower decrease even further..cheers again guys
