  To address poor ultimate vacuum in your Rothenberger Water Pump, first, ensure the pump has been running long enough, as the final vacuum level depends on the duration of operation relative to the volume being evacuated. Next, check for any leaks in the connections or the system; switch off the pump to see if the vacuum level holds. Also, verify that all connections and equipment used are appropriate. If issues persist, further assistance may be needed.

  If the vacuum gauge on your Rothenberger Water Pump isn't moving while the engine is running, first, verify that the pump is actually sucking in air. If it is, the vacuum gauge itself might be damaged. However, if the pump isn't sucking in air, the non-return solenoid valve could be blocked. If the problem persists, further assistance may be needed.
