Hi all
I am new to this forum so if I put in too much information please forgive me. I have a WB Heatslave 18 25 oil combi boiler. I have had it for a number of years. I know WB has a great reputation which is why I bought this boiler but it has been temperamental, to say the least.
It has always had a propensity to lose pressure. I have called out engineers on many occasions and even WB came to look at it but it remains unreliable. It is serviced regularly. Currently it is losing pressure again and from my limited knowledge I think it could either be a faulty pressure relief valve or a faulty expansion tank. The latter is almost new so I suspect the pressure relief valve.
My question is, how do I safely check to see if it is this valve that is malfunctioning?
