Have you checked your stop cock?

Find out how to locate your stop cock

If you have recently had work carried out in your house, it may be that your builder or plumber has turned your internal stop cock off and has not turned it back on again. If this is the case you should check with them before turning the stop cock on.

Sometimes if work is being carried out in your area, such as new housing developments, repairs in the estate or maintenance work on a house close by, your stop cock may have been turned off.

If this is the case and you cannot locate the necessary people then please contact us at the details below and we will investigate the situation for you.

Do you have a pump?

If your premises pumps water to storage check that the pump is working.

Can I use my central heating if the water is off?

If your central heating system has been installed by a registered contractor it should be run from a separate expansion tank in the attic.  This water should not be affected by a water main shutdown and it should safe to run the system. However you should check with your installer to confirm.


Water supply has been returned to my kitchen only there is no water upstairs in the bathroom?
This occurs in some plumbing systems after a water shutdown.  It may be an airlock in your system and you may need to engage a plumber to eliminate it.   The aim is to keep shutdown of supplies to a minimum. However, the property owner is responsible for maintaining internal plumbing systems.

How do I get rid of an airlock?

Following a disruption to water supply some households may get airlocks in their internal plumbing system. The airlock is generally in the hot water system and most likely the result of faulty internal plumbing.

The following steps can be followed if you do get an air lock however it is advisable to contact a professional for advice:

Firstly make sure all hot taps in the house are in the closed position. Then either proceed with either Option 1 or Option 2. The Final Step applies regardless of whether you use Option 1 or 2.


If the hot and cold taps in the kitchen are separate i.e. not combined in a mixer tap, the hot tap should be turned on. If there is an airlock, no water will come from the hot tap. A short length of hose should be used to connect the hot and cold taps in the kitchen only. Turning on the cold tap will result in the cold water being forced through the hot water system and this will force the air which is causing the airlock back into the water tank in the attic.


- OR –


If there is a mixer tap in the kitchen, the hot tap should be turned on. With a cloth in your hand (to help reduce water squirting out) block the mixer tap and turn on the cold water tap gently. This should force the cold water back through the hot water system, forcing the air into the water tank in the attic. Care should be exercised when doing this in case of accidental scalding with hot water. 


Let this run for 1 – 2 minutes, then turn off the cold tap and let the hot tap run for 1 – 2 minutes to confirm that the air lock is cleared. If the air lock is not cleared, repeat the procedure one or two times more. If this is not successful, contact a plumber and get them to correct the problem. In rare cases the cold water taps in wash hand basins or the bath may also be air locked. This procedure will also work for them, but is more difficult as a long length of hose is necessary from the kitchen cold tap to the nearest wash hand basin or bath tap.
