Hope someone can point me in the right direction.
About a week ago my combi boiler (Erocal Senetor) shut down due to a lack of pressure. On checking the Pressure safety valve I could see that water had been blowing out. I read several post from the group and other sites that said that the problem may actually be in the expansion vessel, so I checked that by pushing in the schader valve to see if water or air came out.
Water streamed out, which I thought had confirmed the vessel to be US. However the following day I did the same again and air with just a small spray of water came out of the valve untill the pressure dropped down to zero. Using a foot pump, with the sytem open I pumped up the ex vessel to just under 1 bar and topped up the system via the loop to 1.5 bar. Bugger, the schader valve was leaking on the ex vessel so I tightened the black cap up as much as possible.
My question is:_
Is it normal for the Ex vessel to push water then air out from the sheider valve if the vessel is US.
Can a leaking schader valve be fixed or will I have to get a new ex vessel to be on the safe side anyways?
Many thanks
