Radon Mitigation System Photos

Here are a few radon mitigation system photos to give you the general idea of how a system looks and affects the appearance of a home. The system pipe can be run through the house or run on the outside of the home only... if no other options are available. A properly installed system will always be piped through the house to either the attic or an attached garage. By doing so the amount of potential condensation produced will be decreased and the fan will have a longer life.

In colder climates, condensation in the winter will produce ice in the pipe above the fan therefore curtailing the systems ability to reduce radon in the building. Experience has shown that when temperatures drop below zero both day and night, there will be some decrease in system efficiency, regardless of where the fan is placed. But without a doubt the outdoor systems stay iced up longer and at higher temperatures.

This shows some of the basic features of a system. Note... this is an outside example, which does have to be used in some cases. Only about 5% of the mitigation systems installed by our company end up on the outside of the house. Outside installations are much easier to install and more profitable from an installers point of view, so make sure the outside option is used only if you really need it!

The radon pipe starts at the sump pump basin, which is sealed to maintain suction under the basement.

Here is a radon fan installed in the attic. The fan produces very little noise. In some cases a slight hum is all that can be heard within the house, even at night when all is quiet.

A manometer is placed on the pipe to measure air flow. This assures you that the fan is functioning. A periodic radon test will need to be performed to make sure that your level stays where you want it.

When a vent pipe passes through a fire rated wall such as the wall between the house and a garage an intumescent fire barrier is needed. What for?...if a fire starts in the garage the plastic pipe will melt first and the fire barrier will plug the hole where the pipe enters the house. This slows the spread of the fire into the house.
