I have a Worcester 28CDI boiler.
The pressure keeps dropping from 0.5 bar to 0.2 bar after the CH has been on for 3 hours. Whilst the CH is on the pressure rises to 2 bar.
The boiler has been serviced by worcester and have been told the fault is definately not with the boiler.
I have attached tissue paper to each radiator valve and no water leaks have been identified.
I added the Plumb sealer from B&Q on Wednesday evening (PlumbSure Central Heating Leak Sealer Concentrate) through a radiator. This if anything has made the water pressure drop more quickly.
Should I now try Fernox F4 leak sealer or will this cause more problems?
Your help / advice would be very much appreciated.
