The internal parts in jet pumps for shallow well pumping systems wear down over time. The easiest thing to do is get a replacement pump to quickly restore water to your home. Here is how you can replace the jet pump on your shallow well pumping system.

You Will Need:

  • New Jet Pump
  • 2 Pipe Wrenches
  • 2 Rubber Gaskets
  • Screwdriver
  • Teflon Tape

Replacement Pump

You will need to obtain a replacement pump that suits your particular system. Most pumps have a sticker on them that will tell you how much horsepower the pump uses and the gallons per minute (GPM) the pump produces (if your pump doesn't have this information, contact the manufacturer to get it). You should purchase a new jet pump that matches the specifications of your current pump to make sure it matches up with your current water pumping system.

Remove Old Pump

Before you start, unplug the old pump from its electrical source. If your system is hard-wired (meaning its directly connected to a circuit breaker and is not plugged into an electrical outlet) you'll need to unscrew the wires from the pump's electrical panel. The wires are color-coded in a hard-wired system so you know how they go on the new pump. Remove the pump and set it aside. Open a faucet to make sure you release any residual water pressure in the water lines. You need to disconnect the inlet and outlet pipes running to and from the pump before you can remove it.

Installing New Pump

Set the new pump in the space occupied by the old pump. You'll need to connect the male ends of the pipes into the pump – the male ends have threads that screw into the female ends on the pump. Place Teflon tape or plumbers putty on the end of the male ends – this will keep water from leaking through the pipe connections once water pressure is restored to the system - wrap the male ends at least five times with the tape. Screw the male ends into the pump and tighten the connections with a pipe wrench.

Restore the electrical power by either plugging the pump in or reconnecting the wires (remember, the wires are colored-coded, so you want to place the same color wire to the same color screw on the pump's electrical panel). Turn on the pump and prime it like you normally would to restore water flow to your house. Open a faucet to release any air in the line (this may sound like there's a hammer pounding its way through the system) and wait until water flows out of the faucet. Turn off the faucet and check for any leaks now that the system is pressurized. If there aren't any water or air leaks in the pipes, you are done with this project.
