Hi All
Just recently with no changes to the system i am daily having to bleed upstairs rads. Its a vented system with CW Feed and expansion tank.pipe work & plumbing are original (approx 20yrs old )however new boiler,pump ,hot water valve ,stats and programmer 2 yrs ago all fitted by qualified plumbers. system has been fine till now.Does not seem to be any leaks anywhere. when I put my finger over the vent pipe i get a small vacum so I am assuming this is how air is entering system.I think this also results in water being forced back into the expansion tank and it then overflowing .Any help would be good
