How to Install a Radon Fan
A radon fan is specially made to mitigate the radon levels in your home. Radon is an odorless gas that results from decaying uranium. It is an invisible gas that possesses natural radioactive decay and can be very harmful if trapped in buildings. The radon gas finds its way into your home through floor drains, dirt crawl spaces, sump pumps, wall cracks, foundation cracks as well as through well water. The radon fan is designed to purify the air in your home and free it of the radon gas that is known to cause lung and stomach cancers.
It is not easy to fix the radon fan but the following guidelines give an insight on how to do the installation.
Tools and Materials Needed
- In-line radon fan
- PVC vent pipe
- Rotary hammer
- Wet / dry vacuum
- Demolition hammer
- Right angle drill
- Putty knife
- Smoke pencil
- System monitor
- Hack saw
- 5” cement drill
- Flexible concrete crack filler
- Insulating foam straw sealant
Step 1 - Mark Hole
Using the smoke pencil, mark the hole on the floor where the PVC vent pipe will go through.
Step 2 - Drill Holes
Using the rotary hammer, drill several holes. These will be around the outline you have made of the pipe.
Step 3 - Chip Out a Hole
Using the demolition hammer, chip out a hole that will hold the PVC vent pipe.
Step 4 - Clean the Dirt
Using the drill with a soil auger, pull out the dirt that is under the floor.
Step 5 - Dig a Hole
Dig a hole in the dirt with your hands until it is 20 inches deep.
Step 6 - Insert the Vent Pipe
With the hole dug, it is now time to insert the PVC vent pipe inside it. Having set it, route it and make sure that it goes up to the attic through the walls.
Step 7 - Stuff the Base of the Pipe
Using the foam rubber backer rod, stuff the base of the pipe. Make sure that the pipe does not completely touch the basement floor. It should be suspended slightly.
Step 8 - Seal the Hole
Using the hydraulic cement, seal the hole containing the pipe to ensure that the pipe is firmly fixed.
Step 9 - Connect the PVC
Now that you have pushed the PVC pipe up to the attic, connect it to the radon fan.
Step 10 - Connect the Roof Cap
Now that the radon fan is firmly connected to the PVC pipe, push the pipe up through the fan and into the roof. Once on the roof, connect the roof cap.
Step 11 - Installation
In the basement, install the system monitor that will ensure that the radon fan is functioning well.
Step 12 - Drill a Hole in the Basement
Using the drill, drill a hole in the basement that should be at least 1 inch in diameter. Turn on the fan and using the smoke pencil, check the fan’s draw. Your radon fan is now installed and ready to work!
