i have a baxi combi range 105e of which the water pressure has dropped to zero. I have advised it should be on between 1-2.5, how do i build this back up?
you need to find the cold water service in to your boiler . this will normaly be via a filling loop which has a valve to allow water flow to be opened and closed. fill (by opening this valve) to the required pressure (then close it) then bleed system via radiators (using a radiator key)( bleeding is simply allowing any air to escape the presurised closed system) , when bleed through is compleet then top up pressure if it has droped slightly. refer to lighting instructions on your boiler and be warm then have a beer as a reward!!!

hi, there should be a filling loop or at least two tap type connections on the cold feed and central heating return pipes. This will be where to fill it up.
