Cured fault but still have a slight water leak were manifold joins valve, and the boiler still won't hold bar pressure. Any ideas if boiler has other faults ?

If you are constantly losing pressure in the heating system you could try the following to establish the cause: Check all visible joints including radiator valves and connections for obvious signs of leakage. Ensure that there are no leaks to any under-floor pipework. 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 and terminates outside. 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 you should do one of the following to get advice or help: contact your installer I hope this will help Regards Rafal
