Radon Sump Pump: Is It Worth Your Money?

Many individuals are unaware that their radon sump pump might cause flow into their basement. A radon sump pump is a harmful gas that can accumulate and cause various health issues, such as cancer, lung disease, and heart disease. 

Fortunately, there are a few ways to keep hazardous radon gas from entering the home generated by your sump pump.

In this post, we’ll discuss everything from how to test a radon sump pump system, such as a sump pump cover, and which radon sump pump is the best rated to keep your home safe.

Radon sump pump

A radon sump pump is a prefabricated plastic container installed in foundations to collect ground gases like radon. You attach piping to it to control radon extraction and other potentially hazardous earth gases.


How To Test The Radon Sump Pump System?

There are numerous methods for testing a pitcher pump with a radon system, and we’ll go through the most common and simplest one here:

  1. You must first identify the outflow pipe. When you locate the exit pipe, you will observe that it is emptying water from your sump pump outside your home. 

As a result, you should inspect it as soon as possible to ensure that it is not clogged with debris or dirt. You must check that the pipe is directing water away from the foundation of your property.

  1. Any debris or dirt that has gotten inside the centrifugal pump must remove immediately to ensure that the pump does not clog in any situation. 

The radon sump pump is typically put in a crawlspace or basement near the foundation walls of a structure. Radon mitigation without a sump pump is not an option for any house or foundation.

  1. The first and most important approach to test your passive radon system sump pump is to trace both of your hand pump’s electrical wires. The hydraulic pump’s cord plugs race back into the floating cord plug. 

As a result, both cables should be unplugged automatically, with only the rope pump cord inserted into the outlet.

  1. Your pump is fine if you hear humming when you switch on the water pump. This means that both cords must connect in the same manner as before (first the float cord, then the float plug into the pump cord at the back). 

Sump pump radon mitigation costs are neither too high nor too low; instead, they fall somewhere in the middle.

  1. Because not all electro pumps have two wires, the technique will differ from testing single-corded impulse pumps. They are as follows:
  • Pour roughly twenty liters of water into the pit of your pitcher and steadily pump until there is afloat. Your rope pump should activate as the float lifts. 

It has been turned on, the water will start pumping out, and it should turn off automatically once it has rinsed down all the moisture. You must repeat this test to ensure that your gadget is operational.

  • If pumping that much water into your centrifugal pump is impossible, you must lift the float and monitor whether the pump turns on. 

On the other hand, the hand pump should run for at most 20-30 seconds. Otherwise, the engine will ruin.

These are a few options from which you can select the one that best meets your needs.

Radon sump pump prevention

Since of your health, preventing the radon sump pump from entering your home through your sump pump installation is critical. If your basement is not radon proofed, the radon gas produced by the sump pump installation can leak through it. 

Once radon has entered your home, you will plague by many terrible health issues. The key to reducing radon is maintaining an active drainage system and doing frequent tests.

Radon gas

Radon is a radioactive gas that is inert, colorless, and odorless and can cause various health issues, including lung cancer. It can infiltrate your home from the earth, making a crack or foundation leak a big problem without a vent pipe or radon fan.

Best basement waterproofing systems

The easiest way to keep radon out of your home is to seal any cracks and install a radon reduction system with a monitor to check the current radon level. The best mitigation and removal systems connect to the basement drain tile system, radon sump pump covers, and radon sump pump crock system.

Radon sump pump cover

A radon sump pump cover is necessary to put over your basin and contain any soil gases that seep into the pit. The sump lid should be airtight to hold a high radon level until a radon mitigation professional can be hired to remedy the problem.


The Original Radon/Sump Dome is the ideal cover. This cover is suitable for passive mitigation and has a hole in the center for a radon pipe and discharge pipe, eliminating the need to drill your own.

Radon sump pump removal fan


The RadonAway RP145c is our recommendation for the best radon sump pump  removal fan. This fan has a water-hardened impeller and runs almost silently, so you’ll never know it’s on. 

The fan is seam sealed to prevent radon leakage, and the motor is thermally sealed to ensure that it continues to run even after extended use.

This fan is simple to install, and most individuals can do so with tools from their garage. One of the main reasons we preferred this model over others is that it is the fan that plumbers use to remove radon from their homes – so you know it works!

Radon sump pump-rated crock

Since radon enters your home through the earth, an airtight basin or crock is the best way to keep it out. A decent sump basin should be deep enough to accommodate your sump pump and water level – and secure enough to fit inside the sump hole. 


The Parts2O FPW73-19 is top rated Crock. It is suitable for most basements and is reasonably priced.

Radon sump pump fans and monitors

A radon sump pump fan can help keep this deadly gas from accumulating in your basement, and a monitor can alert you if a radon gas buildup is discovered.

If a buildup of soil gas is found, we propose installing a monitor and a radon vent pipe in every basement.


Another valuable option for continuing radon sump pump tests is installing a radon sump pump monitor that connects to your local Wifi. When a high radon level discovers in the basement or crawl space, an alarm will be sent immediately to your phone.

Summing up

You should check your home frequently since improvements to your home or shifting soil can create changes in airflow through the house and raise radon levels. Standard water can provide you with a free radon sump pump test kit and assist you in interpreting the results.

If you have increased radon levels in your home, installing a radon fan system is an excellent approach to address the issue. Radon fans function by sucking in air from your home and exhausting it outside. 

Radon fans may usually install by a trained contractor. They require very little maintenance once installed and will offer you peace of mind knowing that you and your family are secure from radon exposure.


1. What alternatives to radon sumps are there?

Radon sumps are an efficient technique to reduce indoor radon levels, although there may be better options in some cases. One such option is a positive pressure system.

2. Can a radon sump pump be used to reduce gas?

Yes, radon sump pumps lower radon gas levels in buildings by sucking air from radon gas entry locations and releasing it into the atmosphere. These are normally sealed, rotating extraction fan units positioned within or outside the building with a discharge point.

3. What way will most effectively reduce radon levels?

The best method for lowering indoor radon levels is an active radon sump equipped with a fan. If the ground is covered in concrete or a membrane, sumps perform well beneath solid and suspended floors.

4. Are radon sump pump covers effective?

Yes, It is an effective way to eliminate odors from your sump basin. Also, radon sump pump covers prevent debris from falling into the sump pit and prevent discharge lines from becoming clogged.
