General FAQ’s

What causes a radon removal system to fail or lose effectiveness?

All radon removal systems will eventually become restricted or fail entirely and radon fans can quit for a variety of reasons. They may overheat or the bearings might seize. Sometimes, something or someone changes the electricity powering the fan or accidentally shuts it off. Objects sometimes fall into the piping system that can cause the fan to slow down or stop. Some of the items retrieved from inside radon fans have included branches, leaves, walnuts, hickory nuts, roofing debris, nails, bats, rats, mice, squirrels, chipmunks, birds, snakes, rocks, children’s toys, baseballs and tennis balls. Sometimes the flow gets restricted due to cold weather, ice or snow causing a freeze up at the exhaust point preventing radon from escaping. And sometimes the fan just plain reaches the end of its life cycle and is worn out.

Do any of your radon system alarms measure or test for radon?

No. All of our units monitor the pressure and flow of the radon mitigation piping system itself by utilizing a pressure sensing switch built into each of our units. Our radon system alarms do not measure or test for radon, carbon dioxide, volatile organic compounds, smoke, fire or any other known hazards.

What’s the best way to maintain my radon system alarm?

Other than checking it occasionally, no maintenance is required. (Replacement of battery when needed for battery powered units.)

How long will it take to get my order?

We typically send out all orders within 2 business days and we use Standard USPS Ground Shipping whenever possible. So depending on your location, you should receive your products within 5 to 10 days.

If I have a problem with my alarm and need to send it in for repair or warranty work, what should I do?

Please be sure there really is a problem with the alarm by first checking the vacuum tube and power source. Then review the OM&M Owners Manual. If that doesn’t provide any answers, please send us an email describing the problem and one of our technicians will contact you as soon as possible. If the unit needs to be returned for warranty work, we will provide you with a Return Merchandise Authorization (RMA) number and will be more than happy to repair or replace your unit free of charge if still under warranty. If out of warranty, please contact us so that we can assist you in determining the problem and finding a solution.

How often should I retest for radon?

Retesting for radon is recommended at least once every 2 years.

Do you provide “Free Shipping”?

Shipping costs are already included in the price of our products. We have chosen not to use the words “Free Shipping” as there simply is no such thing. The Post Office, UPS and FedEx all charge for their services and either you or the company you are dealing with will have to pay those fees. To say otherwise is not being completely honest. There is no such thing as a free lunch unless you find a bag sitting on a park bench with a sandwich in it… but would you eat it?

How often should I check my alarm?

Whenever you are nearby.

Which alarm is the best one?

They all are designed for different needs and desires. The best one is the one you like the most!

How do I select the best radon mitigator for my home or building?

Most states certify or license radon mitigators and testers so make sure the one you select is registered with your state. If your state does not register radon professionals, make sure the one you hire is a member of at least one of the radon industries qualifying organizations such as AARST or NRPP or NRSB. Then make sure they include one of our alarms on all of their installations!

Should I shut off my radon mitigation system when I go on vacation?

No. We recommend never disconnecting your radon mitigation system unless there is a problem with the system. If you disconnect your radon system, radon (and other potentially harmful gases) will start to re-enter the building as soon as the radon system is powered off.

Should I disconnect my radon system alarm when I go on vacation?

Maybe. There really is no point in having an alarm unless someone is going to be there to see it or hear it but if you do disconnect power to the alarm, please make sure to re-establish power as soon as you return.

Should I select a plug-in or battery powered model?

Plug-in models have many benefits over battery powered units. #1. Plug-in models never need to have their batteries replaced. #2. Plug-in models will continue to warn occupants of a problem until the problem is addressed or the unit is unplugged. Battery units will only produce a warning until the battery runs out. #3. Plug-in models maintain loudness/brightness unlike battery powered units. #4. In the event of a whole house power failure, plug-in models do not sound an unwanted warning while battery units will. #5. Plug-in models have bright LED lights that can be easily seen from a distance to show the condition of your radon removal system. #6. Plug-in models come with an extra long 8’ power cord.

Battery models have many benefits over plug-in units. #1. Battery models can be placed in locations where electricity is not available. #2. There are no cords to run or plug-in. #3. Plug-in units are required to be plugged into a circuit not being used by the radon fan - not a concern for battery powered units. #3. Battery models cost less to purchase. #4. Other battery powered alarms typically only emit an audible warning sound or light for a very short period of time. With our advanced technology and a fully charged battery, when your radon removal system has a problem, our battery powered alarms can sound for over a week or flash for up to a month.
