What are you noticing?*

Radon alarm or a light/sound

The manometer (U-tube) looks wrong

I can’t hear the fan

A noise

Water, ice or snow

My radon test came back high

Something else

Where is the sound or light coming from?

By the sump pump or a battery box

A smoke or carbon monoxide detector is chirping

Not sure

On or next to the radon pipe

NOT A RADON SYSTEM ISSUE

This is your sump pump’s battery backup alarm, not the radon system. It usually means the backup battery is low or the sump pump needs attention. Please call a plumber. Sump pumps are the homeowner’s responsibility.

NOT A RADON SYSTEM ISSUE

A chirping smoke or CO detector usually needs a new battery. This isn’t part of your radon system.

Your radon alarm (RadonAway RSA1) is a small box mounted on or right next to the radon pipe, connected to the pipe by a thin tube. Sump pump backup alarms sit by the sump pump or a battery box. Smoke and CO detectors are on the ceiling or wall.

What does the radon alarm show?

Green light blinks (3 quick flashes about once a minute)

One chirp and a yellow light flash every 5 minutes

No lights at all

Red light blinks about once a minute, no beeping

Beeping, and the red light flashes (repeats every minute)

Beeping, and the blue light flashes

Tip: Press Hush briefly to silence the alarm. Holding it 5+ seconds changes the delay setting.

NORMAL

Your system is working. The green light blinks 3 times about once a minute when the alarm senses suction.

NOT COVERED – TRY THIS

The alarm’s own battery is low. Replace the battery (see the label on the alarm). This is not a problem with the fan.

Did that fix it?

Yes

SUBMIT – LIKELY WARRANTY

Please fill in your contact info below and we’ll contact you.

TRY THIS

Press the Test button. If it beeps and all 4 lights come on, the alarm works.

What happened?

It beeped and lit up

Nothing happened

NORMAL

The alarm is working. In normal use it only gives a short green blink about once a minute, which is easy to miss.

TRY THIS

Replace the battery and press Test again.

Did that fix it?

Yes

The alarm is sensing low or no suction in the radon pipe. Let’s find out why.

What do you see in the manometer?

The liquid is higher on one side

Both sides are even

No liquid, or very little

It’s cracked, broken or knocked off

NORMAL

That’s exactly how it should look – it means the fan is pulling air from under your home. (Even liquid = problem. Uneven = working.)

SUBMIT – $125 FEE MAY APPLY

Damage to the system isn’t covered by the warranty, but we can repair it. This is usually not covered by the warranty. If you’d like us to come out, a $125 service call fee may apply. Fill in your contact info below.

Radon fans are mounted outside the living space and are designed to be very quiet. The manometer is the best way to tell if it’s working.

Look at the manometer. Is the liquid higher on one side?

Yes

No, it’s even

No liquid / can’t tell

NORMAL

Your fan is working.

What do you hear?

Gurgling or bubbling from the sump pit

Pulsing or surging at the fan

Humming or vibration inside the house

Whistling near the sump pit lid

Rattling, grinding or squealing at the fan, or it’s louder than it used to be

NOT A RADON SYSTEM ISSUE

This usually means water is building up in the drain tile or sump and the fan is pulling against it. Check that your sump pump is running. Sump pumps are the homeowner’s responsibility.

TRY THIS

Make sure nothing is touching, hanging on or leaning against the radon pipe, and that it isn’t resting against a wall or duct.

Did that fix it?

Yes

SUBMIT – LIKELY WARRANTY

Please fill in your contact info below and we’ll contact you.

TRY THIS

This often happens after sump pump work, when the lid’s seal gets disturbed. Check that the lid is seated and the seal isn’t damaged.

Did that fix it?

Yes

SUBMIT – $125 FEE MAY APPLY

If the lid was opened or changed by someone else, the repair isn’t covered. This is usually not covered by the warranty. If you’d like us to come out, a $125 service call fee may apply. Fill in your contact info below.

This can be a sign of fan wear. Your fan is covered for 5 years. Please fill in your contact info below and we’ll contact you.

Look through the viewing port on the sump lid. Is the water high in the pit?

Yes

I can’t tell

No, the water is low

NOT A RADON SYSTEM ISSUE

When the water in the pit gets high, the radon fan pulls air through the water and it gurgles. That means the sump pump isn’t keeping up or isn’t working. Check your sump pump or call a plumber.

SUBMIT – LIKELY WARRANTY

Please fill in your contact info below and we’ll contact you.

What do you see?

Ice or snow at the top of the pipe / exhaust

A snow drift is covering the fan or pipe outside

Icicles on the fan or ice trap

Drips inside the pipe or near the manometer

Water leaking from a pipe joint inside the house

Water in the basement, or the sump pit is overflowing

TRY THIS

Gently clear the snow by hand or with a broom. Never use a shovel or snowblower near the fan or pipe.

Did that fix it?

Yes

NORMAL

Some ice from condensation is normal in cold weather.

Is the fan completely covered in ice?

Yes

SUBMIT – LIKELY WARRANTY

Please fill in your contact info below and we’ll contact you.

NORMAL

Small amounts of condensation running back down inside the pipe are normal.

SUBMIT – LIKELY WARRANTY

Please fill in your contact info below and we’ll contact you.

NOT A RADON SYSTEM ISSUE

This is a sump pump or drainage problem. Please call a plumber right away.

What was your result (pCi/L)?

Please enter a number greater than or equal to 0.

Enter the number from your test report, for example 5.2

Type of test

Do-it-yourself kit

Digital monitor (e.g. Airthings)

Professional test

NORMAL

Good news: your result is below the EPA action level of 4.0 pCi/L, so your system is doing its job. Radon goes up and down from day to day and by season. We recommend retesting every 2 years.

During the test, did the manometer show one side higher than the other?

Yes

I didn’t check

NOT COVERED – TRY THIS

It looks like the fan wasn’t running during the test. Do the Power check below, then retest. You can retest yourself, or we can do a professional retest for a fee.

Were windows and doors kept closed for 12 hours before and during the test?

Yes

Not sure

TRY THIS

Open windows and doors change radon readings. Retest with the house closed up, at least 48 hours, in the lowest lived-in level, away from the sump, kitchen and bathrooms. Tests in winter often read higher.

Did your retest come back under 4.0?

Yes

NORMAL

Good news: your retest is below the EPA action level of 4.0 pCi/L, so your system is doing its job. We recommend retesting every 2 years.

Since your system was installed, have any of these happened?

Remodel or finished basement

New furnace, AC or air exchanger

Sump pump or drain work

Addition built

New cracks in the floor or walls

None of these

First, find the small clear tube that runs from the manometer into the radon pipe. Is the end pushed into the pipe?

Yes, it’s in the pipe

No, it had slipped out – I pushed it back in

Not sure

The tube goes into a small hole in the radon pipe. If it has slipped out, or is just resting against the pipe, the manometer will read even – even when the fan is running fine.

TRY THIS

Wait a minute, then look at the manometer again.

Check the manometer. Is one side higher now?

Yes

NORMAL

Your system is working. The tube had slipped out, so the manometer couldn’t read the suction.

Does your radon fan have a power switch, and is it ON? If there is one, it's usually on the outside wall or in the attic, right next to the fan. Not every system has a switch.

Yes, it’s on

It was off – I turned it on

There’s no switch / I can’t find one

TRY THIS

Wait 5 minutes, then look at the manometer.

Check your breaker panel and any GFCI outlet (an outlet with Test/Reset buttons) the fan or alarm is plugged into. Was anything tripped?

Yes – I reset it

No, nothing was tripped

Did it trip again?

Yes, it keeps tripping

SUBMIT – LIKELY WARRANTY

A breaker that keeps tripping can mean an electrical problem with the fan. Please fill in your contact info below and we’ll contact you.

Now look at the manometer (the U-shaped tube on the radon pipe). Is the liquid higher on one side than the other?

Yes, one side is higher

No, both sides are even

There’s no liquid / I can’t tell

NORMAL

Your system is running again. If the alarm was going off, it will reset on its own. Press Hush once to silence it.

Is it extremely cold outside, or is there ice or snow at the top of the radon pipe?

Yes

Can you hear the radon fan running, or feel it vibrating when you touch it? Only check if you can get to it safely – many fans are outside, but some are in the attic.

Yes, it’s running

I can’t tell / I can’t get to it (for example, it’s in the attic)

SUBMIT – LIKELY WARRANTY

The manometer shows no suction, so your fan may have stopped working. Radon fans are covered for 5 years. Please fill in your contact info below and we’ll contact you.

SUBMIT – LIKELY WARRANTY

The fan is running but the manometer shows no suction. There may be a blockage or a loose pipe. Please fill in your contact info below and we’ll contact you.

TRY THIS – NORMAL IN COLD WEATHER

In extreme cold, moisture in the pipe can freeze at the top and block it. This is normal for radon systems in our climate during cold stretches. It isn’t a defect, there’s nothing to repair, and it isn’t covered by the warranty. Don’t hit or chip at the pipe – plastic pipe breaks easily in the cold. Near the fan there’s an ice trap with a cleanout cap. Remove the cap so the system vents at ground level until the ice melts, then put the cap back on.

Check the manometer. Is one side higher now?

Yes

No, still even

NORMAL

Your system is venting again. Remember to put the cleanout cap back on once the ice has melted.

NORMAL IN COLD WEATHER – NOT A WARRANTY ISSUE

That’s expected while the top of the pipe is frozen. It will clear on its own once temperatures rise. Leave the cleanout cap off until then, and check the manometer again after it warms up. A service visit can’t fix frozen exhaust, so there’s no need to submit anything.

Is the small clear tube still attached at both ends – to the manometer, and pushed into the hole in the radon pipe?

No, it’s loose

Yes, it’s attached

TRY THIS

Push the tube back on firmly, then check the liquid again.

Did that fix it?

Yes
