Outside radon system

We try to keep the system on the back or side of the house.  We also use the most energy efficient radon fans.  1/3 of our systems use a 19 watt fan that can save $500 in electricity over 10 years compared to competitors radon fans.

If the radon fan is installed outside, we offer matching aluminum downspout to minimize the appearance of the system

Matching downspout color

This is our outside fan. Condensation will drastically shorten the fan life unless an insulated by-pass drain is installed.

By-passed water is drained out of system to reduce moisture under the slab so you have a dryer basement.

Extended fan life

The only available location for this fan was the rear deck.

So we added a cover to reduce it's appearance

Weatherproof  screening is installed on the exhaust to prevent critter entry.

The PVC radon piping is routed along the ceiling and down beside the exterior foundation wall.

The piping is installed through the concrete floor.

Gravel or dirt is dug out of the suction hole before the PVC pipe is installed.

We always use a shop vacuum to minimize dust from drilling.

We prefer to put the suction next to the sump pit rather than into the sump.

If you have a dirt floor crawl space we seal a reinforced membrane over the dirt and install a radon vent pipe with a damper to control the airflow to collect the gas under the membrane

Sometimes we can route the radon piping up through a closet and into the attic.  This may be an easy approach in a ranch house

Sometimes we can route from the basement into the garage and then up into the garage attic.

If you route the radon piping through the garage, you must use a fire collar at the top and bottom of the pipe to maintain the garage fire rating.

This is a PA DEP requirement

The radon fan can sometimes be installed in the attic.  This fan is installed with rubber boots and includes a disconnect switch within eyesight

If the radon fan is in the attic we use a standard plumbing flashing to vent through the roof.

Sealing cracks using urethane caulking is a PA DEP requirement.

Sealing enhances the system performance and allows us to use a super efficient 19 watt radon fan that is very quiet.

Sump pits are sealed using aluminum flashing and silicone caulking to allow easy removal.

A one way floor drain is installed as per PA DEP requirements.

In this case a view port was installed to allow visibility of water in the pit.

A U-Tube Monometer is installed on the pipe.  The difference in height between the two oil columns indicates the FAN is running.

The PA DEP requires an information package be attached to the system

After the system is running, we use a very sensitive digital micro-monometer to measure the negative pressure created under the slab by the radon system.

Even a Slab on Grade home like the one in this picture can have elevated radon.

The fan and outdoor suction is under the white fan cover box

This slab on grade house has no basement.  The radon piping was installed from the outside into the sub-slab.  With no inside exposed piping the system needs an outdoor magnehelic system indicator

Radon Systems don't automatically reduce radon levels.

It is important to choose a company that can determine why a system is not reducing the radon levels.

We have expensive radon sniffing equipment and pressure reading instruments that allows to accurately improve systems and not just guess how it should be done

I hope these photos give you an idea of how we pride ourselves on doing a first rate job.
