Water Level Testing of the vertical turbine pump

● Install an airline that extends from the surface to 2’ above the inlet of the vertical turbine pump.

Securely attach the airline to the vertical turbine pump assembly but take care not to crimp the airline. Measure and record the exact vertical length of the airline during installation.

● Attach a depth gauge or pressure gauge and snifter valve to the airline at the surface.

● Connect a tire pump to the snifter valve and expel all the water in the airline (if using a gauge with a movable dial - set the dial to 0 first).

● If you used an indirect depth gauge with a fixed dial: The reading on the dial after the water is expelled will be the level of water above the bottom of the airline (Dimension Z).

● If you used a direct depth gauge with a movable dial: Set the dial to 0 prior to expelling the water from the line. Use the tire pump to expel the water from the airline. The reading on the dial will now be the static water level (Dimension X).

● If you used a pressure gauge: The reading on the dial after the water is expelled will need converted from PSI to feet.

Feet of water = 2.31 x PSI

After converting to feet, this measurement is equal to the level of water above the bottom of the airline (Dimension Z).
