On Friday my boiler ran continuously for ages, in investigation this was my megaflo cylinder demanding heat. There was water pouring through the tundish and the motorised valve red hot.
I have refilled the air bubble and all seems OK (for now) on inspection Inoticed discolouration on the motorised valve. Can anyone tell me if thus is a cause for concern.(link below to photo on Google drive)
