Turn off the gas supply

at the meter. Open windows,

do not turn any electrical

items on or off.

Call Southern Gas Networks (SGN)

immediately on 0800 111 999.

If the leak is on your pipework

equipment (the customer side of

the meter) SGN will normally turn

off the supply and advise you to

contact your local Gas Safe

registered engineer.

Call us and we will attend ASAP

If you are constantly losing pressure

in the heating system you could try the

following to establish the cause by:

Checking all visible joints including

radiator valves and connections for obvious

signs of leakage.

There needs to be consideration to

potential leaks to any under-floor pipe work.

Check that there is no water being

discharged from the pressure relief valve

(sometimes referred to as an overflow).

This pipe usually goes from the

boiler through to an outside wall

where it terminates

Check this for signs of dripping. If it is wet,

this may mean that the pressure

relief valve is faulty.

In either case, if your heating system keeps

losing pressure, for advice or

help you should:

Contact your installer

This is normally due to a build up

of air in the radiator.

This can usually be cured by bleeding

the radiator using a key.

Have a cloth ready to catch the drips

as the water can be dirty.

This can occur on older systems and is

often due to a build up of sludge or

Magnetite in the bottom of the radiator.

Excessive deposits in a central heating

system indicate that the water has not been

treated with a corrosion inhibitor over

the life of the installation,

or perhaps the inhibitor has been emptied at

some point and not topped up?

Other indications are noisy pumps, sticking

valves, poor warm up times,

intermittent radiator

warm up and boiler overheating.

Although it is often possible to effect an

improvement by adding a chemical

‘central heating restorer’ to the system or

disconnecting the radiator and flushing it

outside with a high pressure hose.

However, ultimately the most permanent

remedy is professional flushing &

cleaning.

It’s usually found on an internal wall,

often under the Kitchen sink. However

properties that have been extended or

converted, typically to multiple occupation,

may not seem to have one.

Other places to check are the Garage,

downstairs bathroom and Utility room.

If you can’t find an internal stopcock,

an external stopcock can usually be found

under a small square iron or plastic cover

in the pavement.

It sometimes needs to be dug out & turned

on & off with a special turnkey. If you are

in trouble with a stopcock
