Hi everyone I'm Scott..I recently bought a house and decided to re plumb myself..fired up the heating for the first time today and found that the hot water was pumping out of the vent pipe in the attic into the f and e tank I thought the speed of the pump was mayb to high so ran it on speed one but this just slowed the water flow slightly coming from the vent I decided then to close the valve coming out of the f and e tank feeding the heating circuit and the water coming from the vent stopped..from this I think that the water is circulating in my f and e tank I drew out the way I have plumbed my heating circuit and will try upload the photo any advice would be greatly appreciated
