It is very difficult to say without seeing your specific installation. We assume that this problem did not exist before you attached the flexible loop but happened after you had pressurised the system.

Some systems have a valve at both ends of the flexible loop connection. Have you opened both but closed only one? If you say water is pouring out of the Central Heating System then whether the water mains are on or off is not material, the water pressure in the central heating system is driving the water out and your valve is not sealing this off. Have you perhaps over pressurised the system and is this water the excess pressure being released, if so it should stop after a short while. Other than that iIt sounds that a valve is jammed .

If it is none of the above and you have previously taken out one of British Gas’s Homecare agreements with the appropriate level of cover we recommend you request a visit from a British Gas engineer who should be able to identify the cause and adjust / repair your system.

Hi,
I have repressurised my combi boiler, but I can’t remove the flexible loop without all the water pouring back out. Doesn’t seem to matter which way the taps are (closed or open), and doesn’t matter if I turn the water off at the mains.
What am I doing wrong?
Thanks

It is not clear what you mean but if you suspect that your boiler exhaust gases are being vented into the house ten this is a very serious matter. You should switch off the boiler and open the windows to let fresh air into the house. Also ensure that the other members of your household are not exposed to the gases.

Without delay get a Gas Safe (was CORGI) registered plumber to visit the house and arrange to make repairs to the flue, they can also advise you on any actions you should take in the interim.

It could be low pressure, that certainly could be a reason why the filling loop cannot increase the pressure in the water system above 0.9 bar – but this may not be the only reason.

If you telephone British Gas they will be able to provide you with a fixed price quote for attending and working on the problem.

Our hot water has recently only been staying hot for a few minutes before going cold. I also regularly have to turn the tap on and off several times or put the heating on to get the hot water to start up at all.Could this be due to low pressure? The pressure is around 0.9 and i have tried to repressurise it but nothing happens when i turn the stop tap on the filling loop.

It is very difficult to diagnose central heating systems remotely, particularly on the limited information available. You do not advise whether the central heating is hotting up and hence we cannot ascertain whether it is a shower issue or a boiler issue.

If you have taken out an approiate British Gas Homecare service contract you should telephone the helpline number you have been provided with and an engineer will call to help remedy your problem. If you have not taken out any boiler service agreement British Gas have a heating repair service which could help. If you telephone 0808 178 2098 and explain your issue you will be provided with a no obligation fixed quote for fixing the problem.

Richard, Whilst you say you have had the PCB changed, the system checked and the element cleaned none of these seem to have cleared the problem. Call back the plumber who did this work, tell them they have not solved the problem and ask them to complete the job you have paid them for.

You will appreciate that we cannot solve plumbing and heating problems based on a few snippets of information within a web site comment.

I have an Ideal Response 120 Combi Boiler and the pressure is constantly at 3 (recommended to be between 1 and 2). This means that two or three times a week it does not fire and heat the water on demand. When it does fire I hear the ‘bang’ as the safety valve releases and it works ok for a few days. How do I reduce the pressure in the system and keep it down and what is causing the problem? Also, if the pressure is too high is this what is causing it not to fire? I have had the system checked, PCB replaced and the element cleaned.
