How to Install Check Valve on Sump Pump?
Sump pumps are specifically designed to remove the water that accumulates in the basement basin of a building. It takes the water from the basement to a dry well outside in the street or public drainage. But you have to know how to install check valve on sump pump correctly.
Many people do not realize how bad a sump pump is required for their building until they experience their basements being flooded. Sump pumps must be installed in buildings having basements to avoid your basement or your backyard from flooding because of the water basin or pit underground.
How Does It Work?
Sump pumps run by electricity. So whenever it detects water rise, it starts to run the machinery to do the work exporting water from the pit to a dry well. There are many sump pumps in the market with an automatic switch, which saves the sump pump from overload, which can cause the pump to burn because of it. To keep a check and balance on the sump pump to avoid it from burning out because of overload, a check valve is installed.
What Is A Check Valve?
Sump pumps can run all day long to clear out the water from your basement. This draining if the water is essential to keep your foundations firm and intact. To make sure the water that is being pumped out of the water pit is not running back into the pit again, we install a check valve. The check valve prevents the water from coming back into the water pit. It will only activate the sump pump when it detects the water to avoid the sump pump from burning out from running.
How is a Check Valve Installed?
The installation of the check valve is not that hard. You just need a few tools and some labor to install it correctly. The installation method is described as under in three parts. Let’s take a look at how to install check valve on sump pump correctly.
1. Preliminary Requirements:
The first part of the installment of the check valve includes the following initial requirements, which must be followed step wise to avoid any impediments later in the process.
Take Measurements Of The Drainage Pipe:
The first step to installing the check valve is to take measures of your existing drainage pipe. You can only get the right fitting of the valve check when you have the correct sizes for it.
Most drainage pipes come with the measurements labeled on the pipe, but just in case yours does not have it, then you have to measure the diameter of the pipe connected to the sump pump. You can take the measurements of the opening of the pipe that is connected to the pump emerging from the pit. Or if you already have a check valve but want to install a new one, you can note down the measurements by removing the old one.
Buy A Check Valve According To The Size Of Your Drainage Pipe:
The diameter of the valve is more important than the length of it. So when you are purchasing a valve, focus on the width. Your measurements can manually be noted by measuring the diameter of the pipe or in case of an old valve, simply check its size.
Other than the size, check for the different brands of the valve. Valves vary from 3.2 cm to 3.8 cm in diameter, so the right diameter size will help you out in picking the correct valve.
Buy The Necessary PVC Screws And Cement:
To install the valve, you must purchase a PVC pipe. It is highly recommended for a sump pump as it is a type of plastic that cannot be easily damaged and is waterproof. To install the valve on the pipe, you must purchase the following necessary fittings.
Go to a hardware store and get the following items for the installation;
- PVC nuts.
- PVC couplings.
- PVC adapters.
- PVC cement.
- Cement applicator.
2. Operative Part:
The operative part is the first surgical part of the installation of the check valve. It must be followed stepwise with precautions to avoid any mishaps.
Switch Off The Pump Before Starting The Installation:
As you know, sump pumps are generated by electricity, so to install a check valve, you must switch off the pump to avoid any mishap.
You can do that by unplugging the cord of the sump pump.
But before deactivating, the sump pump allows it to drain all the water into the pit, so the water does not fall back when the pipe is opened.
Find The Location Of Your Pipe In The Wall Or Ground:
The next step is to locate the pipe that connects to your sump pump. This pipe is not that long and connected directly to the sump pump, so it is not hard to identify. In case there are several pipes, locate the one that is connected to the pump following it out of your house.
Make sure you do not pick the wrong pipe as you will have to cut it open to install the valve.
Remove A Section Of Pipe To Install The Valve In Case The Pump Is Already Installed:
If you have a sump pump already installed, you need to remove as in cut a section of the pipe where the valve would be installed by the use of PVC cutter or hacksaw. Before cutting the pipe, measure the length of the valve to have accurate measurements of the part which has to be cut so the valve can easily be fitted.
The Old Valve Must Be Removed To Install The New One:
In case you have an old check valve already installed and want to install a new one, you must remove the old valve. And since the removal of the valve will leave that area vacant for the new valve, it can be easily installed. The valve is vertically installed between the empty section of the pipes.
Smoothen The Edges Of The Pipe:
With the help of 180-grit or up to 220-grit sandpaper, file the edges of the pipe to smoothen them before fitting the screws and couplers to install the check valve. The edges of the pipe can be rough and sharp, so installation can be complicated as you have to look out for your hands. To avoid that, file the edges to save yourself from unnecessary cuts.
PVC Nuts To Be Fitted:
The next step is to fit PVC nuts on the edges of the pipes. They are equipped to avoid any leakage and hold the valve together. So they have to be installed first. Note that some check valves have metal clamps that act the same as the nuts and couplers in PVC. If your valve has metal clumps, then you need to adjust the tightening them.
PVC Couplers To Be Fitted:
Next step, adjust PVC couplers on top of the PVC nuts. These are small tubular-shaped connectors which connect the valve with the pipes each from both sides of the pipes. Screw these couplers to secure them.
Secure It With PVC Cement:
To keep the PVC fittings in place, apply a cement coating on to the PVC nuts and couplers to secure the connection of both pipes with the check valve. So there is no chance of leakage possible.
Install The Valve:
After the cement has been applied, install the valve and cement any connecting part of securing with a cement coating. Allow it to dry for 2 hours before operating the sump pump, so it is intact entirely.
The last step is the execution of the whole installation process. You must execute the purpose you installed the check valve for.
Test Your Check Valve:
So now, finally, you can test your check valve by switching on your sump pump. Plug the cord of your sump pump and generate it to test whether or not the valve is successfully installed. As the water pressure increases, you will hear a flap inside the valve as it opens for the flow. Check for any leakage etc. like draining the water back to the pit. In that case, switch off your sump pump and fix the connections of the pipe and the valve.

We have sump pumps to the rescue as they take the water out of the water pit before it floods your basement or yard. This is why you need a sump pump. For buildings having basements, it is a must-have.
While wrapping up the installation of the sump pump check valve procedure, you must take precautions like unplugging the cord for safety hazards, locating the right pipe, making proper and accurate measurements, to get the best results. It can easily be carried out by any person who is good at handling hardware equipment.
