  If your Neptun Water Pump isn't intaking water, it could be due to several reasons. The non-return valve might be dirty, requiring cleaning. Ensure the pump chamber has a water connection by filling water into the intake. Check that the intake line is airtight and not exceeding the maximum suction height. Make sure intake line is closed and check suction height.
