Ah, so the pressure in the accumulator will always match the maximum of the PRV at best, and if below PRV maximum, the mains pressure?

Output at PRV is 3.5 bar Pressure in accumulator is 1.5bar less (so 3.5bar - 1.5 = 2 bar) 3.5bar (output at prv) + 2bar (pressure in accumulator) = 5.5bar So the 5.5bar must be static pressure I guess. When multiple taps are turned on, it must maintain dynamic pressure at static pressure rate...

I was thinking more in terms of accumulators. Not fitting one - just trying to understand the science behind them. If the incoming mains is 6 bar, and the PRV reduces it to 3.5 bar, and the pressure in the accumulator is recommended to be 1.5 less, then the max pressure in the accumulator would...

Can someone confirm my understanding of pressure vessels is correct? A PV is supposed to operate at mains pressure. The instructions state that it must be pressurised to 1.5 bar under mains pressure. You also have to fit a PRV rated at 3.5 bar infront of the PV. So would the pressure in the...
