System Design Requirements

The most important part of being a radon contractor is designing an efficient and up to code system for the homeowner. As we mention in most of our articles, airflow is the most obvious goal of system design. But there are also some often looked over aspects as well.

This even comes down to the material used. For example some contractors use thin wall pipe which is not allowed in the state of Ohio, schedule 40 is necessary. 

It can also come down to the parts used on the exhaust point. For example you can't use a 90 degree fitting or a rain cap on top of the exhaust. To stop anything from entering the pipe, a critter guard is acceptable as long as the openings in the wire mesh are at least 1/2" wide.

One of the most important design variables is the exhaust point which has to be at least 10' away from openings such as windows or 2' above them in the state of Ohio. As well as 20' above the ground. For example, this was used in a job we performed in Cuyahoga Falls, OH where the roof was taller than 20' so we just ran the pipe up to the desired height and put a 45 degree fitting on to direct the air away from the siding.
