Unlock Air in pipework

If your tap does not supply water, it might be air locked (Usually the cold tap on the kitchen sink).

Step 1: Link the blocked tap to a working one

Attach a length of hosepipe to the affected tap and connect the other end to a working direct feed tap.

Open the two taps for several minutes. The pressure of the mains water will force the air back out of the pipes. Then turn off the air locked tap first.

Step 2: Repeat those steps 

Repeat step 1 and step 2 a few times to release the lock and allow water to run properly.

Release the hose from the higher of the two taps so that the water in the hose drain into the lower sink.
