Brief External Subslab Depressurization Video HD 1080p

This video shows how it is possible to remove radon from a home without any visible components of the system on the interior.

I am a radon contractor in Philadelaphia, PA. I appreciate your videos very much! Thanks for being willing to share your experience with others.

I really appreciate that Tony! Glad to be of service.

Great additional hints about seeking out loss areas in the substructure. 🤗

Thanks Brian. I appreciate it.

do you do pressure field extension testing?

I see that some people install condensate bypass piping. They claim it protects the fan. But I would have to say the vast majority do not have them. Is putting one in just a preference?

Hi Pride Mechanical. I did a couple many years ago when I first started. It's a little time consuming. Might save a little wear on the fans but since they are such work horses, it's hard to say. At the time I felt like it was costing suction as well. I stopped doing them but if someone out there swears by it, I'll listen.

@Radon Man thanks for the response. Seems like very little condensate would be able to build up after the fan. The fan is pulling subslab air. Ground temps around here anyways are consistently 50-55f. Not like sending hot combustion gasses outside from a furnace. Plus the fan is blowing air over any condensation that might form. Seems like you are right that all that hassle and a loss of suction (by short cycling discharge air) leans in favor of not installing traps. Also, using a condensate bypass will definitely introduce more moisture laden air going into the intake of the fan. Maybe not exactly ideal.
