What should the pressure be on a Baxi boiler?
What should the pressure be on a Baxi boiler? The Baxi engineer said that the pressure was down to 0.1bar when he visited but he put it back up to 1 bar we just tried to check the pressure again with foot pump but cos it is knackerd we couldn't tell what was in the boiler .... but there was some air released when we took off the cap. How long to repressurise a Baxi combi boiler? It depends on the current pressure of your combi boiler. You will need to flush water in the valves for around 10 seconds....
