Shabbat: Pumps
  • Shabbat: Well Water
    You may use water from a pump-operated well on Shabbat (as on Jewish festivals), as long as the pump operation is not a psik reisha (inevitable and immediate consequence of using any water tap).
    Example You may use water from a well if it comes via an automatic pump that operates to fill a reservoir once the water level drops, but you may not:
    • Operate the pump directly.
    • Turn the pump on or off.  
    Note If there are variants to this situation, ask a rabbi.
