Low pressure from un-vented cylinder - faulty PRV?

I mean that all hot taps fed from the unvented must be all at the same static pressure.
Something odd about an outside tap apparently giving 4 Bar.
He still does not understand dynamic pressure!

Really?
You must be reading a different thread to the rest of us - the pressure at the cylinder and upstairs outlets was indeed (significantly) lower than the kitchen tap, that was the whole point.

I can explain this - the garden tap isn't being used and is getting a build up of pressure. The static pressure (garden tap) was 4.2 bar tonight, I then measured 2.5 bar at the incoming main... took the garden tap reading again and, lo and behold, it matched at 2.5 bar.
And just for Tony, the dynamic pressure is 1.8bar!
You should also have a double check valve on the garden tap, which will, hold any increase in pressure during off peak hours.
No, you'll always be limited by the pressure regulator of the Gledhill.
If you changed to an OSO, and got an installer who knew what he was doing, then they can be uprated... Otherwise, you are stuck.

The accumulator will even out the pressure for you, but still at the Gledhill's limit of 3 bar.
I doubt it would be worth the hassle and expense.
