Some pictures of radon testing and mitigation systems being installed in Michigan homes.
Dave is finishing up an installation by clamping the piping to the basement wall. We could save a few dollars by running the pipe straight up from the sump, but durability would be questionable. In the enlargement, note the clear Lexan(TM) sump cover and the pressure gauge on the pipe. The second, smaller, pipe is the sump discharge line. Both pipes have rubber couplings for easy maintenance.
Jill is aligning the vacuum fan before installing the vertical exhaust stack. Note the white rubber coupling at the base; it isolates vibrations and makes for easy maintenance. A second coupling will go on the top.
Pat is loading tools back into one of our vans — RADON1. Others you’ll see on the streets are RADON2, RADON3, MRRADON, MSRADON and NORADON.
Jill adjusts the exhaust deflector so it will not blow directly at any part of the house. This minimizes recapture, and also prevents moisture damage. Note that the exhaust is kept below the roofline, but still above the eave as EPA requires.
Jill removes the temporary alignment screws, allowing the fan to float free of the siding. This prevents transmission of vibrations to the house. On brick homes we can sometimes leave the fan fastened without causing a noise problem. (See next).
Different home. Fan mounted to chimney, with piping assembled so that system is not visible from window. See below for interior shots of this home.
Pat finishes mudding around the slab penetration. The jog at the bottom of the pipe is necessary to avoid the footing that holds up the foundation.
Chris installs pressure gauge, while Pat gets set to label the circuit breaker as required by EPA guidelines.
Pat uses a smoke puffer to make sure that we’re not pulling air from a drainpipe.
Have A Question About Radon Treatment?
Super quick and efficient service of installing a radon mitigation system in the house we were selling. The installers were very knowledgeable and explained the system and the information to pass on to the buyer's. Definitely would recommend.
(a) at least ten feet off the ground,
(b) above the eave (not necessarily the edge) of the roof, and
(c) either ten feet away from, or two feet above, windows.
