Help! Topping up CH system (was Bleeding Radiators)
I just went round 2 radiators bleeding the air out of them. On the 2nd
there wasn't much air at all coming out. On checking the combi boiler, the pressure bar has fallen to 0. It was only just over 1 to begin with. What do I do now? Will it top up automatically somehow? How do I do it myself? Is it unwise/dangerous to put the CH back on now? What about using hot water? Help! |

This valve usually needs a bit of flexible pipe to connect it to a second valve on the mains water supply side. Once connected both need to be opened and the pressure restored. 1.2 bar would normally do when the water is cold. It is then normal to both close off the valves and remove the flexible link Tony |
