If the pipes are corroded and difficult to remove, use a pipe cutter to cut the pipe near the pump. Ensure a bucket or tray is under to catch any water or sewage that may spill out.

Step 03: Remove the Pump from the Basin

The next step is to remove the sewage ejector pump from the basin. Depending on the design of the pump, this may involve removing bolts or screws that hold the pump in place. You may need to use a pry bar or other tools to loosen the pump.

Before removing the pump, it is essential to note the position of the discharge, vent, and inlet pipes. Remember to take pictures or mark the position of the pipes to avoid any confusion when reconnecting them later.

After removing the bolts or screws, gently lift the pump out of the basin, not damaging the float switch or other electrical components.

Step 04: Inspection and Replacement of Damaged Pump Parts

When inspecting a sewage ejector pump, there are several crucial internal parts that one should carefully examine. The power and switch connection, impeller, motor, float switch, and check valve are all components that can wear down over time and experience various types of damage.

As such, it is important to know how to inspect these parts for damage and how to replace them if necessary.

The power and switch connection should be checked to ensure that it is properly connected and that there are no loose or broken wires. Check the electric wire connection and wiring diagram to ensure they are correct.

Also, check the insulation on the power and switch connection for signs of wear and tear. If any of these components look damaged or worn, replacing them with new parts may be necessary.

The impeller is a critical component of the pump that moves the wastewater through the system and out to the sewer. Therefore it is essential to check for any signs of wear or damage, including cracks, chips, or eroded parts.

A damaged impeller can cause problems with the pump’s efficiency and could lead to further damage to other internal components. In such cases, the impeller would need to be replaced as soon as possible to prevent further damage.

The motor is another critical component that powers the impeller and moves wastewater through the system. Inspecting the motor for damage involves checking for any abnormalities, such as overheating, electrical shorts, or rusting.

If any damage is noticed, it is necessary to replace the motor to prevent the system from failing or shutting down unexpectedly.

The float switch is a vital part of the ejector pump that turns it on and off based on the water level in the pit. Inspection for damage involves looking for broken or missing components, wear signs, and debris buildup.

Any damage to the float switch could cause the pump to malfunction, leading to water or sewage backup in the system. In this case, the switch would need to be replaced to ensure proper functioning.

The check valve is another critical component of the ejector pump that prevents wastewater from flowing back into the pit after being pumped out. Inspection of the check valve involves checking for any cracks, chips, or signs of wear that could lead to it failing.

A damaged check valve may cause wastewater to flow back, creating a blockage in the system and causing significant damage. A replacement would be necessary in such cases to prevent further issues.

Step 05: Clean the Basin (Optional)

While you have the sewage ejector pump removed, it is a good idea to clean the basin. You can use a hose, suction device, or other cleaning tool to remove any debris or sediment accumulated in the basin.

Be sure to wear protective gloves and eyewear, as you may encounter hazardous materials. Rinse the basin thoroughly, and disinfect it using a mild detergent solution.

Step 06: Reinstall the Pump

Once you have repaired or replaced any damaged parts, it is time to reinstall the sewage ejector pump. Follow the manufacturer’s instructions for securing the pump in place. You can then attach any necessary electrical wiring and piping.

Step 07: Reconnect the Plumbing

It is time to reconnect the plumbing with the sewer ejector pump back in place. Start by reattaching the discharge pipe first, then connect the vent and inlet pipes. Tighten the nuts into place with a wrench or pliers, ensuring that the connections are secure and leak-free.

Step 08: Restore Power and Test the Pump

Finally, it is time to restore power to the sewage ejector pump and test it to ensure it works correctly. Turn on the circuit breaker or plug in the pump and listen for any unusual sounds or vibrations.

Run some water through the pump to confirm that it is flushing correctly and that there are no leaks in the plumbing. Dispose of sewage or wastewater properly, following the relevant regulations and safety procedures.

And maintain your sewage ejector pump regularly to prevent any future problems.
