Walking into the basement my client asked me what the device on the far wall was and my answer was, "It's NOT exactly a professional radon remediation system."
There are a lot of things that make up a PROFESSIONAL radon remediation system.
> It would be a completely enclosed system, with sealant around the base where it enters the basement floor. Sometimes the basement floor slab is sealed also, where it meets the foundation wall.
> A solid tube so no leaking can occur.
> A wall switch so it can be controlled, with its own wall receptacle, not a part of the basement circuitry.
> A test tube with colored water inside so you can see if proper suction is taking place.
Something else that cannot be discounted is that a PROFESSIONAL radon contractor should install the system! You know, licensed, insured, trained...!
Usually in a corner off out of the way, or in a closet, a PROFESSIONAL would not put it in the center of the basement family room wall as it is here.
Another pretty important criteria with any radon remediation system is where it discharges!
Typically the tubing connected to the fan will run up an exterior wall of the house (sometimes through the attic space and roof) to discharge high above anyone's ability to breath in the discharge.
The system here blows its air about 6" above the soil and UNDER the (very clean and cared for) deck!
I could not actually see the discharge, but could hear the fan! It was blowing right under the center of the photograph!
In this house some inventive homeowner did some of that there reading on the Internet. He learned EVERYTHING he needed to know about radon and radon remediation. Everything! And he went at it!
My recommendation: sometimes you look at something and don't initially know what it is, but when thinking further can actually figure it out. The donut fan is the tip off here that this is to remediate radon! And I think I'm correct in thinking that someone did some research to know exactly what to do to take care of that pesky radon problem all by himself! We don't need no stinkin' professionals! Wow, where is Billy Jays when you need him?
