If the pin is still not coming out enough then there is a restriction in the divertor valve and it is best to replace the whole thing

Customer: replied 1 year ago.
Divertor valve ok
There's a cartridge at the cold inlet part num 248051
Cost of Venturi cartridge £15

Does the pin come out if you run 2 taps

Customer: replied 1 year ago.
No just the same

Try removing the cartridge on the cold inlet to see if you can get the flow rate through the boiler.

See if you can measure the time to fill a bucket before and after
