Don’t dwell on it! We’ve got you covered with the step-by-step guide for sewage ejector pump installation. First up, there are essential things to put in place before installing a new sewage pump. How about we check them out?

Importance things to do before installing a new Sewage Ejector Pump

To start with, take time to read the manufacturer user’s manual that comes with the packages. It’s important to know that there are different sewage pump producers in the park. Each brand produces a variant sewage pump for use. Likewise, each pump is compatible with various accessories, including float switches and many more. To be on the safer side, carefully check the user’s manual for all caution and instructions.

Since all ejector systems come with different local building codes, always check the regulations and ensure the sewage ejector pump meets the system requirement. This requirement includes venting. If you want to install the pump on outdoor applications, check the minimum and maximum basin depth. It doesn’t end there! Make sure you also look into the diameter of the PVC piping and many more.

Furthermore, to fix the ejector pump on the go, ensure all the tools or equipment for installation are made available. This tool includes protective gloves and shoes, sump basin, valve, 2-inch outlet, towels, power drill, hacksaw, box cutter, pipe wrench, zip ties for secure wiring, sewage pump alarm, electrical cord grommets, coupler, PVC pipe and others.

How to install a new Sewage Ejector Pump

Before installing a new sewage ejector pump, ensure you remove the existing pump from the ejector pit. However, unplug the pump from electricity to prevent stories that touch the heart. So, to properly install the new sewage ejector pump. Follow this guide!

Prepare the basin

First and foremost, thoroughly inspect the empty ejector pit. There’s virtually no way you will remove an old pump without any loose dirt and debris stuck into the basin walls. So, ensure to clear all sorts of junk. Consequently, to prevent any unpleasant odors. What more? Check the basin for any damage signs or deformities, then repair it or get a replacement to prevent any gas leakage or unforeseen circumstances.

Fix new check valve

Securely install a new check valve before placing the sewage pump in the basin once it’s cleaned. Meanwhile, there are different check valves you can opt-in for depending on your choice and application area. Consider a quiet check valve for any basement bathrooms. Hence, they produce little or no noise while working.

To prevent an unwanted water backflow, try installing a ball valve above the primary check valve.

Examine the Pump and Float switch

Next, test the pump and switch to ensure it works perfectly well. All you need to do is plug the new sewage pump into a particular circuit, carefully fix the float switch at the right height of the ejector and activate the float switch. With this, make sure the ejector pump is on. Meanwhile, avoid operating the switch too low or high to prevent malfunction.

Install the Sewage Pump and Adapter to the PVC Pipe

Since your pump and switch is in suitable condition, the ejector pump and adapter to the discharge pipe. Use the primer and PVC cement to attach the male-threaded adapter to an end of the line.

Once you’re done with this, use the wrench to tighten the adapter end to the pump. Whereas, the mistake many users made was to over pull the adapter to the sewage ejector. Consequently, it leads to crack or other damages.

Drill weep holes in the basement walls

This is one of the essential procedures to install a sewage ejector pump in the basement. You cannot conveniently remove water from the sewage pump without drilling the weep hole.  Besides, the process prevents water that can compress the air in the PVC Pipe.

Drilling a hole is simply easy as long as you have the right tool. Use the grilling tool with a 3/6 “bit, the pump at an angle and measure 2 finger width above the male-threaded adapter fixed. At a 45-degree angle, drill for proper water drainage.

Take Discharge Pipe measurement and Cut

The PVC pipe dimension you use depends on the length or size of the check valve. So, ensure you pay attention to the heights of the valve before cutting the discharge pipe.

To make things stress-free, you can measure the old PVC pipe removed and use it to judge the new discharge pipe size.  Be precise with the measurement. Avoid cutting the pipe too short or long for proper fittings. Use a saw and safety knife to maintain smooth edges.

Fix the sewage Pump to the Ejector Pit

Lower the pump to the basin without wasting much time since the PVC pipe is securely debarred and firmly attached. Put the float switch away from the inlet to prevent water from covering the ejector pump. Then, use the zip ties to fix the electrical cord up above the control.

Attach Discharge Pipe to the Check Valve

Use a primer and PVC glue to attach the coupler to the top of the ripped discharge pipe, then fix the check valve. Glide the adapter for the bottom part over the coupler before setting it to the PVC Pipe. Ensure the coupler, discharge pipe and check valve are in alignment. But, avoid fastening it too tight.

Test the Sewage Ejector System

Once the pump is securely attached to the basin, ensure the float switch is in a good state. Likewise, it can move around in the bay without any challenges. Then, plug the pump into the outlet. Use a bucket to fill up the basin with enough water to activate the ejector pump properly.

Secure the Sewage Basin Cover

Before placing the basin cover, use an electric wire grommet to pull all electrical cables through the basin cover holes. Apart from this, ensure the new gasket is fixed and ready to operate. 

Don’t forget to finish installing all essential accessories into the sewage system before you proceed to attach the basin cover. However, loosen up the discharge pipe a bit to effortlessly slide the sewage basin cover over it.

Don with that? Vent a pipe below the sewage basin cover up to 3”. Since you don’t want to keep doing this all time, put a silicone bead all-round the edges of the sewage cover. Then press firmly down to secure the surface properly.

Attach Vent Pipe to the Top of the Sewage Basin Cover

The installation process is incomplete without attaching another vent pipe to the top of the cover in the basin. These pipes are basically to vent out nasty odors from gases and dampen water in the basement.  Once this is done, the sewage ejector pump has been successfully installed.
