The pressure dial is showing 1 at the moment, how do I increase the water pressure to 2.5 that it usually is. Where exactly is the knob to let the water in?
You should have a filling loop under your boiler. Turn both valves clockwise to let water in and increase the pressure to around 2.5.
If your boiler doesn’t have a filling loop, I recommend contacting Worcester’s technical team for assistance: 0330 123 3366.
