Turn off the
water supply

Step 1

Locate the water valve by tracing the hose from the bottom of the tank to the wall.


Turn the valve clockwise as far as it can go.


The valve should be relatively easy to turn so don't force it if it feels stuck.


If your valve won't turn

You might be dealing with rust or calcification. Try twisting it side to side gently. If needed, use white vinegar to dissolve the rust/mineral build-up.
