Defective air volume control 3.
Water coming up from the well 3.
Leak on discharge side of system 4.
It cycles on again when the pressure falls below the pump s cut in pressure.
A shallow well jet pump s pressure switch regulates the amount time the pump motor runs.
We recommend that a licensed contractor install all new systems and replace existing pumps and motors.

Jet pump plumbing diagram.
When this happens it creates a balloon of water that can build up in the tank.
Once this volume has built up then the pressure switch turns off and the water then pushes out into the line providing a more constant flow and pressure.
Taps are provided to accept pressure switch pressure gauge drain valve relief valve sniffer valve etc.
A well s pressure switch turns on the jet pump once the water pressure in the storage tank s bladder drops below a set low limit and turns off the jet pump once the water pressure breaks the high limit setting.
Leak in foot valve use voltmeter to check at pressure switch or terminals nearest pump.
Water going down to the venturi foot valve 2.
If replacing the switch we recommend using one with a 30 5 psi setting.
You have to alter the bladder pressure of the vacant tank to comply with the cut in pressure of the pump in any case.
Mount the pump on a protected base and fastened it down with black screws.
Failure to install in compliance with local and national codes and manufacturers recommendations may result in electrical shock fire hazard unsatisfactory performance and equipment failure.
Drain valve drain easy draining of.
Deep well jet systems are used when the water depth is between 20 and 80.
During normal operation the jet pump fills the pressure tank with water to the pump s preset pressure and shuts off.
We recommend a captive air pump tank.
Install a pressure tank on the delivery side of the pump as shown in the diagram.
Check air temperature where pump is located.
Water supplied to the building i suspect that your new jet pump is a convertible model that can be hooked up as either a 1 line jet pump or a 2 line jet pump and that it came out of the box set up as a 1 line jet pump.
If over 100 degrees f overload may be tripped.
Technically qualified personnel should install pumps and motors.
Leak in the pressure tank 2.
Tank tee connets water line from pump to pressure tank and service line from tank to house.
For wells deeper than 80 a submersible pump system is recommended.
Installed near the tank inlet to hold water in the tank during pump installation when the pump is idle.
It isn t hard to interface the pump to the tank and to associate both to the best well pressure tank system.
Check motor wiring diagram.
As we see in photos on this page a typical 2 line jet pump has three points of pipe connection.
