Hi again. I have just been getting advice on replacing a radiator on my sons system only to have a fuse blow on my system. It looks like the tree way diverter valve is shot. I replaced fuse and when I went to cylinder cupboard i noticed that there was a small ammount of moisture around the base of the diverter( not the compression fittings) also the diverter responds to the cenntral heating commands but then without change in command the diverter goes around the clock to come back to the central heating and hot water command, where it was initially. I am having trouble removing the cover. The valve is a blue switchmaster diverter some 30 years in the system and I assume not replaceable. Any initial advice please. If the opinion is that it is shot could and advice is replacement is there one that might go in on existing unions. It has been put in right near the floor and very little room to manouvre. I am quite competant on tha piework aspect if needs to be chaged. Not my day. Mik
