Baxi Boiler Pressure Too Low: How To Increase!

Learn how to repressurise your Baxi combi boiler and save a few quid with this no nonsense quick video guide.

The Baxi 600, Baxi 800, and Main Eco Compact combi boiler are all the same. If you have a different Baxi boiler, the process will be the same but the filling loops might be slightly different.

You must open one valve fully, then open the other valve slowly until the pressure starts rising on the pressure gauge. Once it reaches 1 to 1.5 bar, close both valves.

If you have two black knobs, turn one anti-clockwise as far as it will go to open it, then turn the other one anti-clockwise slowly until you hear the water and see the pressure gauge moving.

Then turn both knobs clockwise as far as they will go to close them when you have reached the correct pressure.

If your boiler keeps losing pressure, you have a problem with your boiler or heating system that needs to be fixed. Most commonly it's because of a leak.

The blue knob on the left doesnt turn for me, the one on the right does though. I also have 2 black knobs but turning those does nothing.
