Simple question. How do I turn off the flow of hot water to the downstairs taps and washing machine ?.
My hot water cylinder is upstairs but not sure which stopcock to turn. There does not seem to be one on the hot water pipes !!
assuming it is a gravity system there will be a pipe coming down from the storage tank in the loft and going into the bottom of the hot water tank this should have a red circular valve on it this is the gate valve close this valve this will stop the cold water entering the hot water tank and the hot water will stop flowing as it all works on gravity and pressure,open the hot taps to take out the surplus water first
try turning every stop valve off! Cant do any harm so long as the boiler is turned off. U may find they are seized.
If this doesnt work. - Turn off the mains to the house and turn on the hot taps. Ithe hot tap will soon turn run dry
