How to Install an Ejector Pump

Only a competent and skilled team of contractors should attempt to remove or install a flush-clean ejector pump. Tackling the task of removing and installing flush-clean ejector pumps can prove daunting for unskilled workers. In fact, a flush-clean ejector pump removal and installation may cause serious bodily injury and property damage if poorly executed. Depending on the discharge size, most ejector pumps average between 250 and 350 pounds or more. Additionally, flush-clean ejector pump removal and installation require strict adherence to city codes for plumbing.

Things You'll Need

• Submersible pump
• Tripod and come-a-long
• 2 open-end wrenches
• Hand cart

Instructions

1. Disconnect the power to the knife switch on the motor that controls the ejector pump. Carefully drop in a submersible pump into the septic tank. Connect the submersible pump to the tank's line in order to manage the sewage.

2. Disconnect the electrical wires and pigtail from the ejector pump's motor and recap the ends. Move the pigtail, a piece of wire located between the float switch and ejector pump, to a secure place.

3. Safely remove the motor from the top of the ejector pump without entangling the wires. Secure the spider gasket for the shaft coupling in a safe spot.

4. Disconnect the flange bolt of the ejector pump discharge line. Remove the check valves to the ejector pumps for easier dismounting of the discharge line.

5. Mount the tripod and come-a-long chains to the top and bottom of the ejector pump. Slowly pull the tripod and come-a-long and watch for any signs of the unit's destabilization. Continue to lift the ejector pump until the hatch opens.

6. Open the hatch and locate the flush-clean strainer that connects to the ejector pump's mainline. Carefully climb down the ladder with a couple of open-end wrenches. Disconnect the strainer with an open wrench in a counterclockwise fashion. Dismount the flush-clean strainer and carefully climb back up the ejector pump pit.

7. Using the open-end wrench, unscrew the 9/16-inch bolts that secure the pump collar of the ejector pump tank.

8. Use a come-a-long to winch the ejector pump out of the ejector pump pit. Spin the ejector pump 90 degrees to allow the pump discharge flange to move beyond the discharge line.

9. Disconnect the pump discharge flange once the ejector pump elevates midway. Remove the pump shaft in order to pull the ejector pump out of the pit entirely.

10. Hoist and place the ejector pump onto a hand cart for transport to a repair shop.
