Automatic bleed valves

jor199

Hi I have two radiators in my system each on its own inverted loop I am having problems clearing air out of these two rads everything else works fine they are the last two rads in the curcuit.There is an automatic bleed valves on the top of each of the pipes where they turn down on both flow and return is this correct.I have a sealed system pressure stays constant at 1 bar. Everything worked fine until I restarted the heating after it being unused for about 2 months the pressure was still up and all the other rads heated as normal except these two.

If possible try and bring pressure up to 1.5 Bar. You myght have an airlock in the system and the extra pressure might just move it. Also you will be able to check if the pressure gauge is reading correctly. Someimes there are valves each side of the filling gauge and they may both be closed causing a false reading.

Thanks ntpm seems to be sorted now had increased the pressure after I drained the rads and all is now ok

My pleasure. Just keep an eye on the pressure gauge whenever you vent or refill the system for a couple of days.
