Submersible Pumps – A Step by Step Installation Guide

Whether it’s about choosing the right type of OCTG casing to prevent connection fatigue failure or high-quality submersible pumps to improve wastewater management, the role of pipes and casings is pretty evident in reducing the carbon footprint.

A submersible pump is a tool that includes a completely sealed motor attached to the pump body.

A submersible pump works by transferring the fluid into hoses, which are then shifted to storage tanks and finally to a treatment facility. This pump is used for pumping out septic tanks.

The selection and installation of the right submersible pump can make or break a deal for you.

These pumps are installed in well-constructed water wells. If installed correctly, it can save users lots of hassle and money in terms of future repairs.

Submersible Pumps – Step by Step Installation Guide

You can either install a submersible pump on your own or may also hire a professional to do this job for you. In this post, we’re going to highlight the steps you must follow to install a submersible pipe on your own.


Inspect the Well

First things first, you should carefully examine the well. Make sure you check the depth, casing damage, and standing water level before you get started.

You can check the depth of the well by calculating the distance from the ground to the bottom. To measure the head, you can calculate the vertical distance from the pump to the ground level. To measure GPM, simply calculate the amount of water in GPM the pump discharges.

Carefully Inspect All the Components

The next step would be to examine the supplied components. This step is critical as it will help you follow the right installation route.

Carefully go through the details mentioned on the motor, including the power supply rating. Also, check if it’s a 2-wire or a 3-wire phase.

At this stage, you may also need to check whether or not the pump’s drop cable matches up with the motor cable. Don’t forget to assess that the fittings are compatible with the pump outlet, bore cap, and the rising main.

Once you know all the technical details and specifications, it’s time to fit the motor to pump.

Attach Motor to Pump

To fit the motor to the pump, you must use the supplied lubricant to grease and seal the shaft on assembly. You can either use a poly tape or a thread tape to lay fitting.


If it’s unavoidable to splice the drop cable, make sure the splice is water-tight. You can easily make splice by either using potting or commercially-available splicing kits.

Just make sure you carefully go through the instructions available on the kit before you start the splicing process.

Fix Pump to Water Well

The next thing you need to do is to fix the pump to water well.  For this, all you need to do is to fit and roll out the rising main to pump. Fix the bore cap to the other end of the main.

Roll Out Drop Cable

So you have already fixed the pump to water well. Now connect the stainless steel safety cable to pump the rising main as well as the drop cable. Give space to the rising main so that it can stretch by connecting one end of the safety cable to the bore cap.

You can also tape the length of the cable splice to shield the main. Also, allow some additional drop cable (that you can fold) and fold to the main just beneath the bore cap. This might be needed if you have to replace the cable splice or the motor in the future.

Recheck Assembling

Last but not least, recheck all the fittings to ensure every component is perfectly attached and working.

You can also lower the pump end into the water well with a helper to hold the bore cap end if you’re finding it difficult to handle the assembly because of its lightweight.

Tip to Consider

If you’re still finding it tough to handle the assembly weight, you can also use a roller made from the wheel of your car.

Simply attach a bore cap to your car with the help of a sling and a shackle. Move your car to enable the submersible pump to go inside the well. Move your car towards the well and allow the cap to collide with the roller. You can test the pump by attaching the starter, controller, and safety device.

Give this whole process a few minutes so that the water can reach the surface.

If it’s working well, you can link the required pipework to the cap. Test the entire unit one more time and do whatever changes you need to make on the spot.

Final Words

More or less, all submersible pumps use the same working principle. However, there’s a wide range of submersible pumps available in the market. Also, they differ in terms of design and features.

Make sure you check out all the available options before you settle for one. Submersible pumps are a long-term investment. We hope this step by step guide has cleared your doubts. It’s now easy to install a submersible pump on your own. Isn’t it?
