I am having a new kitchen fitted and the plumbers have turned off the flow of HOT water, I have cold water still through out the house but we need HOT as well.

In the cupboard where my tank is located there is 4 red taps/valves I have tried turning them both ways and so many different combinations I have forgotten what they were to start with.

Can anyone helpe me before I phone and shout loudly at the plumber?

What the plumber most likely turned water supply to the water heater. Locate it and turn it back on and open the others up. Good luck, tom

Where would I locate it, usually?

This would be on the cold water pipe going into the heater. Can you give me a picture? Regards, Tom
