Interior / Exterior Radon System Installation

Interior Systems

All interior piping goes through a lot of consideration of it final appearance. I like to consider the present and future use/s of the space considered for any available options. I make the most of any space needed for the pipe so that you get the most use of the area, this includes attic and garage space. The smallest pvc pipe that can be used is three inches and is most common. A monometer is installed to monitor the air flow of a system. This does not tell you the level of radon.  

Exterior Systems

All exterior piping goes through a lot of consideration of it final appearance. I like to consider the present and future use/s of the space considered for any available options.

Most of the exterior systems I install, do switch over from the pvc pipe after the fan, to a three by four vinyl downspout once outside. Cleaning the downspout before assembly allows all sealants to perform at their best. I seal all joints to prevent air and condensation leakage. I use four screws at all joints, so that it becomes one piece. This product will not rust or dent and can be painted, by the homeowner during or after installation.

All exterior systems are installed with a condensation by pass system. This is not required, but is recommended by “Radonaway”, the manufacture of the fans used. The President of Radonaway told me, “John, by doing this you can now state that you will get fifteen to twenty years from our fans”. Most Radon away fans have a five year manufacture warranty. My systems are also designed to drain most exterior condensation back into the system to prevent as much exterior ice buildup in the winter months. Also, all my fans can be replaced without removing a single part from the exterior of the home.

It is the protocol of the EPA that any piping point straight up at the discharge location, usually twelve inches above the roof line. A screen is installed at all discharge points to prevent animals from entering the system. All exterior electrical line are installed in a gray flexible conduit.
