All You Need To Know About Sump Pump Installation

rain water management

Sump solutions help protect homes and buildings from water damage.  Today, climate change has created weather conditions that contribute to heavier rainfalls.

Most properties, including older homes built without proper basement waterproofing, need water management systems to manage the challenges presented by the weather.

Installing a sump and a sump pump is an excellent way to mitigate the threat of water damage to buildings.

This article considers sumps and how you can install a sump pump.

What is a Sump?

You may wonder – what is a sump, and how does it work with a pump?

A sump is a space or reservoir below ground that holds liquid. In a residential area, a sump collects water from homes; for example, a homeowner will have a sump collecting stormwater (rain) runoff from the roof. Residential homes with basements will likely have sump solutions to prevent water damage or flooding.

A sump may collect toxic liquids or manage large volumes of water or liquids in an industrial setting. Commercial properties often need sump solutions for managing rainwater and groundwater.

To remove the liquid from the sump, depending on its structure, it can drain away—i.e., seep through its walls and floor, and this is how many stormwater sumps work—or, if the sump is watertight, there may be a pipe leading to a drain.  However, most often, a sump pump is installed.

Sump Pump

Once the water reaches a certain level, the pump will activate to drain the sump below a certain point. The pump can be submersible (placed inside the pit) or pedestal (mounted above the pit with a hose or pipe extending into the pit).

You can calculate the sump pump installation cost, which includes healthy preparation and equipment installation.

Optimal Pump Location

It would be ideal to place the pump close to the wall since you must extend a pipe from the pump to drain the drainage water at least three meters from outside the wall.

Step 1

Choose a place convenient for work and where you can make a hole outward in the end beam.


Step 2

Step back approximately 20 cm from the foundation wall to avoid touching the base.

Step 3

Be careful not to puncture the water pipe. If the water is brought into the house through a wall, everything is fine, but check the building codes to ensure where the water supply is installed if the pipe is located under the house.

As a rule, the external water pipe is laid approximately 1.2-1.8 m from the sewer pipe.

Preparing the Drainage Pit

First, you must prepare a well where you will place the pump. You can do this yourself or hire a professional.

1. Remove Concrete Covering

This is a pretty quick job if you can rent an electric jackhammer. Avoid grinding the concrete, but instead, break it into easy-to-remove pieces. Once you have cut the concrete into pieces, pry them up with a jackhammer and remove them.

Continue drilling holes and chiseling the concrete until it breaks into pieces that are easy to remove. If you find steel reinforcing mesh on the floor, you may need heavy-duty tin snips or a cutting wheel to remove it.

2. Dig a Drainage Well

The depth of the well must be at least 30 centimeters greater than the height of the pump sleeve. To remove garbage, use 15-liter buckets.

3. Place the Shell in the Well

Fill the remaining space between the sleeve and the wall of the well with gravel, leaving approximately 15 centimeters to the floor level. You can use any gravel approximately 10-12 mm in size.

Pump Installation

Make a concrete mixture and fill the remaining space above the gravel to the floor level. Level and smooth the filled mixture with a trowel. Once the concrete has set (about 8 hours), you can continue installing the pump.

1. Assemble the Outlet Pipe

Most pumps use 1.5-inch tubing, but it is recommended that you read the instructions that come with the pump to ensure you have the correct tubing. Leave a small section of pipe outside the house, as a flexible hose can be used for the rest of the distance.

When assembling the pipe, test the fit of all sections before you begin gluing them together. Work in a well-ventilated area to avoid exposure to solvent fumes.

Apply glue to the inside and outside surfaces to be glued. The choice of specific components for assembling the pipe depends on the structure of your home and foundation, so a reasonably experienced plumber should perform this part of the work.


To make a hole in the house’s base for the pipe, use a cylindrical saw of the appropriate size. It is best to make such a hole outside the home using a nozzle with a diameter of 5 centimeters.

2. Install Pump

Place the pump in the drain sleeve, connect the end section of the assembled pipe to it, and plug the pump into an outlet.

You may have to drill many holes in the pump sleeve to allow water to enter. The diameter of these holes should be smaller than the size of the gravel so that the gravel cannot fall through them.

3. Check Float Position

The float’s design may vary for different types of pumps, but whatever it is, nothing must interfere with the float’s movement, which must rise and fall freely as the water level changes.

As the drain well fills, the float should rise freely to the level at which the pump turns on and then fall back without getting stuck between the pump and the wall of the sleeve. This is usually achieved by placing the pump in the centre of the sleeve, but it is still better to double-check that the pump is installed correctly.

4. Install Check Valve

Keeping water in the pipe after the pump stops is necessary to avoid endless cycles of turning the pump on and off. Most of these pumps are sold complete with clamps and connecting sleeves, which indicate the direction of water movement. Install the valve on the vertical part of the pipe and tighten the clamps with a screwdriver.

5. Check Pump Operation

Fill the well with water and ensure it works as it should under real-world conditions. Check all connections for leaks, ensure water drains are at your chosen location, and ensure the check valve works when the pump is turned off.

Final Words

The question may not be whether you need a sump and sump pump but whether you will attempt to install them yourself!

If you’re an experienced DIYer, you will likely want to do the job yourself.   However, it is a fiddly job that can go wrong, with disastrous effects like flooding your property, so it’s likely you’ll find that it is much more efficient and reliable to hire an experienced specialist.
