Does radon have to be vented through the roof?

Does radon have to be vented through the roof?

EPA’s Radon Mitigation Standards require vent discharge points to be above the roofline, and no less than 10 feet sideways or 2 feet above any windows or vents.

Can radon run horizontal?

It should be “safe” to terminate the radon pipe 15 or 20 feet above the ground (which exceeds the 10 foot minimum height standard). It is also well over 10 feet horizontal distance from any windows or vents to the sides or above including any soffit vents that may be present.

Can radon be vented through a wall?

An effective and affordable way to reduce radon levels in homes using side wall venting is now available from Tjernlund Products, Inc., the originator and leading manufacturer of side wall vent systems for gas and oil fueled heaters.

Where should radon pipe be placed?

roof and 10 feet or more above the ground, and must be at least 10 feet away from windows, doors or other openings that could allow radon to reenter the home, if the exhaust pipes do not vent at least 2 feet above these openings.

Should my radon pipe have a cap?

Pipe covers can cause your system to freeze over in the winter: When your radon mitigation system is running, it is pulling air from beneath your homes foundation and safely venting it above your roofline. In conclusion, putting a protective cap on the top of your radon system might sound like a good idea in theory.

Does radon settle?

Outside Air – Radon gas from outside air also settles in basements of homes because it is eight times heavier than air. Radon released by tailings from uranium mines was found to travel hundreds of miles and settle in homes.

How do you hide radon pipes outside?

Exterior pipe runs can be camouflaged. A skilled radon gas contractor can run the stack through the exterior soffit rather than around it, another option that enhances appearance. The stack should also be painted to match the color of the siding.

Can radon enter through floor drain?

Radon Enters Through Floor Drains Radon gas, insects, sewer gas, and fumes can enter homes and businesses through floor drains or through a sump. Radon gas is a deadly carcinogen. Installing a Dranjer valve in the sump lid and the floor drain may be all that is required to reduce radon to safe levels.

Is radon higher in vacant homes?

Vacant houses will experience factors that may drive radon levels to lower or higher than normal averages, but the effect cannot be predicted. If the average indoor level is 4 pCi/L, then it is expected that the radon level will be near to that average after 12 hours of a house being closed.

What are signs of radon poisoning?

A persistent cough could be a sign that you have radon poisoning.

  • Persistent cough.
  • Hoarseness.
  • Wheezing.
  • Shortness of breath.
  • Coughing up blood.
  • Chest pain.
  • Frequent infections like bronchitis and pneumonia.
  • Loss of appetite.

How do radon mitigation systems work?

Radon mitigation systems operate continuously actively drawing radon gas from under concrete slabs, sump pit basins, and crawlspace liners. Moisture vapor and other soil gases also travel up through a radon system, since they both are present in the soil.

Do radon systems draw out moisture?

The only downside of a radon system drawing out moisture vapor is the potential for ice jabs in cold winter months. The amount of moisture being extracted from under a home can be quite significant. The moisture travels up and exits out into the atmosphere through the vent pipe on the radon system.

How does radon travel up in a home?

To explain further, radon travels up into a home from deep in the soil. Radon mitigation systems operate continuously actively drawing radon gas from under concrete slabs, sump pit basins, and crawlspace liners. Moisture vapor and other soil gases also travel up through a radon system, since they both are present in the soil.

Why is my radon mitigation system clogged with ice?

The issue of radon mitigation systems temporarily clogging due to ice forming on the vent pipe of the radon fan is very common in cold weather climates. The very nature of a radon system pulling damp air from under structural concrete slabs and crawlspace liners creates this issue.
