Toilet cistern filling injector nozzle sizes

[DIYedboy]

The water pressure in my daughters flat is minimal, I have replaced the red nozzle and the rubber shut off washer. The flow is still minimal, is there a bigger nozzle than the red one?

No - red=LP / white = HP

Which part of Surrey is your daughter in? (I know the area quite well)

Is there an isolating valve in the water supply to the cistern, is it fully turned on ?
Is there debris in the filler valve restricting the flow ?

She's in Worcester park at top of hill,yes isolator valve fully open n no debris. I think I'm going to fit a pair of those new british invented shower booster pumps to H n C supplies have you seen them?

Probably lucky to get 0.7 bar at ground floor in that location!
