in THE MAIN WALL
I have a jennings "vacuum heating pump' which has 2 condensate pumps and 2 hurling pumps. The system will not make a vacuum. Any help is greatly appreciated. The system worked great for the last 60 years.dom..

    won't make vacuum

    Assuming that the pump and controls operate, what is the return temperature as it enters the tank?

    1-Does the tank have enough water for the (hurling) air pumps?
    2- Are return lines leaking? Sucking sound if air pumps work and water leakage when air pumps are off.

    Check seals

    and water level as noted. After 60 years, everyone has a leak problem it is written... I saw one years ago with a nice neat hole between the hurling tank and the main tank, just rotted out in a spot for reasons unknown but it was a steel tank, not CI. Can you check tank integrity?
