Draining hot water tank

moonrakerz

I need to lower the water level in my hot water tank. I have a conventional hot water tank fed from a cold storage tank in the loft.

As the hot water normally comes out of the top of the hot tank under pressure from the cold tank in the loft I assume that I have to drain water from the bottom of the tank to lower the level inside the tank. At the same time stopping more cold water coming down from the loft tank.

The only way that I can see to do this is is via the cold feed pipe into the bottom of the hot tank which comes down from the loft. I will have to shut off the supply from the cold tank in the loft, then using the drain c**k (won't let me put in the correct word !) on the bottom of the pipe, drain the water from the hot tank through a length of hose.

Is this the correct way or am I missing the blindingly obvious ?
VMT in advance.

I would tie up the cold water feed (Ball valve) if there is no stop valve and then run the hot tap until the water flow stops.

That will empty the cold water storage tank, but leave the hot water cylinder full.

You can then take the the top pipe off the cylinder and syphon the water out.

Hi

I would use the above method, but not by draining the tank, unless the valve doesn't turn off tight.
DRAINCOCKS tend to stick so leave it alone.
