Hi,
I'm going to be replacing a hot water tap, and need to turn off the hot water. We've got a gravity fed hot water system (hot water cyclinder fed by a water tank in the loft). Previously, I turned off the cold water and drained the water tank. Bit of a pain, considering I'm on a water meter, and I've lost all my hot water.
Talking to my neighbour at the weekend, he you can get special plugs/seals that can attach to the outflow pipe on the water tank. Think it involves stinking my arm into the tank, and plugging the hole. I've tried a universal plug, and a wine stopper (??) without any luck. Do such plugs/seals exist?
Thanks.
