I have a Vaillant 828E Turbomax combi boiler which feeds an 8 radiator system. Every thing works ok, but I keep getting air in the system and have to bleed two rads upstairs approx, once a week. I replaced the PRV last year as the overflow pipe was dripping and that was cured. The only other problem has been the diverter valve sticking which i removed and cleaned and has worked fine since. Could air be entering at the diverter valve?
The pressure in the system doesn't seem to change (except when I bleed the air) and is between 1.0 and 1.5 bar. Any suggestions gratefully excepted.
