I'm installing a bathroom in a very old property and the boiler is a Worcester 35cdi ii 2005 model and there is no filling key available on site for it.
Would it be ok to bypass it and fit a standard braided hose filling loop from the cold mains to the central heating return on a Worcester boiler so that I can repressurise it without using the inbuilt key filling system?
