Boiler overpressure

[Maulpills]

Hi,
I have a worcester 28cdi boiler which is at 3 bar when the boiler is off.
Boiler was working fine until radiators were removed and replaced by plasterers. Boiler was repressurised too high. How do i repressurise back to 1 bar?

Let some water out. Drain cock or bleed it out via a radiator.

Was the inhibitor replaced?

No to inhibitor.
I tried bleeding water out of radiators but no joy.

What do you mean 'no joy'?

check that the filling loop filling valve is closed then open a radiator bleed valve and empty the water into a bowl until the pressure is correct then close the bleed valve

Thanks both. Rookie mistake - the filling valve wasnt closed. Drained some water out of the radiator and pressure has dropped. Thanks for your help.
