Propane Leak Detector Falsely Activating

Propane leak detectors are a great way to keep your family safe from gas-related hazards such as carbon monoxide poisoning and propane tank fires. These LP sensor alarms operate at a low threshold to alert you quickly to any potential danger, and they come with loud, clear voice warnings in English and Spanish.

Why does my gas detector go off for no reason?

A special additive called mercaptan is added to propane in order to make the gas easier to detect in case of a leak. However, on rare occasions the smell of the odorant may fade or not be present at all due to a number of reasons. For example, the odorant may adsorb (stick to) new or old building materials like masonry, rough wall surfaces, furniture fabrics and drapes. The odorant can also adsorb in underground gas piping and on static or reconditioned propane storage tanks and cylinders.

If you suspect that your Propane leak detector is falsely activating, there are a few simple steps you can take to resolve the issue. First, ensure that the LP detector is not blocked by an object or an open door or window. It should be located in a well-ventilated area where air can flow freely. Moreover, you should avoid spraying deodorants or any other aerosols near the unit because they can set off the sensor.

Next, you can use a propane leak detector solution or thick soapy water to check for a leak. Apply the solution to the connections between the cylinder valve and regulator outlet, or any other connection you suspect is leaking. Then, slowly open the valve and watch for bubbles. Small bubbles indicate a minor leak, while large bubbles suggest a significant leak. Insects are also attracted to propane and will often hover around the gas hose or tank connection, so if you see swarms of insects around these areas, it could be a sign of a leak.
