I had a plumber install a shower pump a decade ago and he took the hot water feed directly out of the side of the hot water cylinder, about 9" down from the top (3" down the cylindrical part). He appears to have used a standard 22mm compession fitting tank connector. There is a white rubber(?) washer behind the fixing nut which has perished and I have water running down the outside of the tank and through the kitchen ceiling.
I have tightened the fixing nut but the washer is starting to break up. It is currently only 'weeping' and I'm catching the water with a cloth. What is the best way of fixing this? I'm thinking that I need to drain the hot water cylinder and replace the sealing washer. I can't work out how the main body of the connector got into the tank unless the plumber went in through the hole for the immersion heater... Should I just go to Wickes, buy a connector and be really careful not to knock the main body into the tank?
