I installed a new grundfos grundfos 15-60 water pump a week ago.
Trouble is my heating does not work until I bleed it? I have bled it two or three times a day for the alst week. It works great after I bleed it but next day air seems to back in system.
My boiler is down stairs and pump upsatirs next to water tank.
Is this normal after changing a pump? Can anyone advise?
