Drain down hot water tank?

[tj]

Hi

Can anyone shed any light on the best way to drain down an electric hot water tank, it is fitted with the standard Chauffe eau Kit, inlet valve and overflow ( 35 euros Castorama) dont see any drain cock.

The only way I can see is to disconnect the cold inlet ( slowly, )

help appreciated

From memory :

Turn off the  old water in

Disconnect the hot water out and open up the pipe on the outlet side.That is disconnect all the French hot water pipes. Open the black tap which lets the cylinder empty

You don't have to undo anything.

Turn off the cold water input on that valve, then open all the hot water taps.

Then turn the knob on the safety valve a half turn and water will flow out of the tank into the drain.

You do not have to but it used to take about one and half hours with the pipe connected versus twenty minutes if you undid the outlet pipe for our small system in France.
