Hi,
I'm trying to get the air out of my central heating system gravity fed since draing down. I have been told that if i put the pump on while i have a hose connected to the drain off point downstairs that it will do it. I thought if I had the pump on while doing that I risk the chance of sucking in more air? am I right or wrong? thanks ps all the radiators are full but air bubbles are travelling out of the transparent hose pipe. thanks again
