Air Ejector Control For Deep Well Water Systems
releases air only, submersible pumps only, 1-1/4"NPT

Pressure Release Valve Adjustment:
  • The HARVARD® plastic deep well air release is factory set at 25 psi
  • Max release valve pressure setting is 40 psi - Min setting is 0 psi
  • Pressure setting is increased by turning the adjusting screw clockwise, and lowered by turning the adjusting screw counterclockwise
  • One full rotation of the adjusting screw changes the setting by 5 psi
How the HARVARD® release valve works:
  • Excessive air in the tank will continue to lower the water level in the tank to the extent of discharging air into the service line
  • As the water level is lowered, the deep well air release float is also lowered, opening the release valve
  • This allows the excess air to bleed out of the tank until the release valve setting is reached (Factory set at 25 psi)
  • As the pressure in the tank lowers to the cut-in setting of the pressure switch (usually 20 psi), the pump starts and forces water and air into the tank until the pressure has reached the cut-out setting of the pressure switch (usually 40 psi)
  • As the water level rises, it raises the float which closes the release valve before the water level reaches the valve; a process that is repeated as the pump cycles

Frequently Asked Questions

Q. "How do you size a pressure tank for wells?"
A.The rule of thumb on sizing a pressure tank is one gallon of drawdown for each gallon per minute of pump capacity. If your pump delivers 20 gpm, then you need a tank with a minimum of 20 gallons drawdown.

Q. "Do you sell submersible pumps for wells?"
A. We offer many types of pumps but we do not sell nor will we quote prices on submersible pumps for wells.
