Pond Boss Forums AERATION Systems questions well water line to pond

CBRanch,

By simply closing the valve, the pump was still trying to pump the water through the end of the pipe. I assume that means you spun the pump off the motor.

The restriction is like taking a McDonalds drinking straw and adding a coffee stir straw to that. Then try to blow air though both of them. It is much harder to blow through the stir straw than the drink straw.
