OK so this might sound like a dumb question.......but is there a "usual" or most common way that air gets into your heating system ????
I seem to be bleeding rads far too often.....so where does all the damn air come from ??? Logic tells me that if you have a leak somewhere on the system, 1 It would show itself as a wet patch sooner or later... 2 If water is getting out then there is obviously a chance that air could get in... I have NO apparent leaks anywhere. So, some general pointers or things to check for would be good to start with....thanks

tends to be thu pump on the return and a smell leak somewhere

but cos the system is under negative pressure it drows air in

rad valve glands are a fave
