Possible Immersion Cylinder Air Gap Failure?


Postby Slightly Soggy » Thu Apr 26, 2018 12:43 pm

Any help on this would be wonderful. Problem is water leaking intermittently through tundish of unvented cylinder. TPRV has been replaced, as has the pressure reducing valve - so it's not them. On heating, pressure on gauge rises above the 2.1 bar it is set at and water comes through the pressure relief valve even though it has not exceeded the 4 bar limit of the valve (noticed it dripping when the gauge said 3.1 bar). Have tried reinstating the air gap several times - the last time it cured the problem for a few days and then it started again. I am guessing the air gap might some how be failing and then activating the pressure relief valve - but can't understand why the valve would activate below its 4 bar limit. Perhaps this is faulty too? Any ideas?
