My open vent system was converted to a sealed one a few weeks ago. A Magnaclean was also fitted on the flow side, after the heating zone valve( not an ideal position but there was no space available on the return circuit).
Following the conversion, I noticed the pressure dropping regularly and the air build up inside the Magnaclean filter indicating a leak somewhere. Because of the constant corrosion and sludge build up in the old system, it was suggested that there were old leaks that went unnoticed due to the good old F & E tank. Also there was damp smell in one of the rooms on ground floor.
The entire ground floor pipework buried underfloor has now been replaced with a new overground layout. Since then I have not noticed any drops in pressure and system seems to work. However, I am troubled by air still accumulating in the Magnaclean bottle. This air eventually ends up in one of the radiators, albeit less frequently.
The boiler is a Gloworm Flexicom (heat only).
Any clues as to the cause of air problems. Could it be related to the siting of Magnaclean filter which ideally should be at the return side of the last radiator. Although Magnaclean say it can fitted anywhere in the system?
