I have a Potterton Performa 24 combi boiler.

Yesterday i bled the radiators and since then the pressure has dropped to low. When i turned the boiler back on it seemed to bring in more water into the system to fill up where the air has been removed.

I understand i need to repressurise the system, by turning one of the taps… but i don't no which tap i need to turn.

I have numbered the photo of the underneath of my boiler, can someone let me know which tap/s i need to turn to repressurise.

Thanks

Open No 4 (5 is already open)and that will allow mains water to refill the system. Afterwards close both 4 and 5. Both valves should remain closed. The hose should ideally be disconnected, but many are left in place.
