MWA-D Flashcards
what are the 2 types of positive displacement pumps
reciprocating
rotary
where does a jet pump sit
on the surface of the water
what is a shallow or convertible well
any well that is 25’ or less
what is a deep well pump
anything over 25’
when is a convertible jet pump used
when water level 25’ to 90’ below ground
where is the jet assembly located in a convertible jet pump
in the water
how deep should the jet assembly on a convertible jet pump be below the drawdown level
5 feet below
how do submersible pumps bring up water
through impellers
where is the pump located on submersible pump
near the bottom of the well
how can a natural spring being used as water source be protected by contamination
through a spring box
where do you find a pitless adapter
on a submersible pump
what is a draw down level
water level which the water level drops when the pump kicks on
what is well yield
the sustainable rate of water flow that a well can draw of a sustainable amount of time
a good well yield is 5gpm
what is the practical and theoretical suction lift of a shallow well jet pump
25 feet = practical
theoretical = 14.7 x 2.31 = 33.9ft
on a deep well jet pump, what valve adjusts how much water goes into the house and how much goes back into the well
the control valve
