Call a Licensed Plumber Right Away

If you suspect a carbon monoxide leak or your carbon monoxide alarm is sounding the alert, ensure everybody is evacuated from your home immediately. If anybody is showing signs of carbon monoxide poisoning (dizziness, headache, upset stomach, vomiting, weakness, chest pain, or confusion), call 911 right away.

Once you have got everybody safely outside and away from danger, it's time to get a licensed and experienced emergency plumber on the case. They will arrive and work on identifying the problem and stopping the leak in its tracks. Here are just some of the checks and procedures your plumber should follow to fix your system and keep you safe:

Check Your Exhaust Vents

Dust and debris can build up in your vents over time and create a blockage. When carbon monoxide cannot escape through your vents or the chimney flue, it could find its way into your home. The exhaust vents are one of the first areas your plumber will check to locate the cause of the leak. Any debris will be completely removed, and your system will be tested to ensure carbon monoxide is no longer being released.

Assess Gas Line Connections

Your gas lines are designed to carry gas safely to your water heater and keep fumes away from the home environment. However, they can be vulnerable to faults, especially if they have been damaged or are coming to the end of their natural life. Your plumber will test your gas lines thoroughly, recommending repair or replacement as necessary.

Repair Your Water Heater

Water heaters work exceptionally well most of the time. However, they are not immune to faults. From leaking vent pipes to blockages and faulty internal components, many problems could cause carbon monoxide to leak from your system. Once your plumber has checked the exhaust vents and gas line connections, they will turn their attention to your water heater and get it back up and running perfectly.

The Importance of Carbon Monoxide Detectors

You undoubtedly have smoke detectors in your home, but are carbon monoxide detectors installed? Carbon monoxide is a silent, odorless, and colorless killer, one of the most significant safety risks for homeowners today. Because it's so difficult to detect, you must have carbon monoxide detectors protecting your family. These inexpensive but invaluable devices will sound an alarm the moment they detect dangerous levels of carbon monoxide in the air.

Placement Near All Gas Appliances

The International Association of Fire Chiefs recommends that there should be a carbon monoxide detector on every floor of your home, including in the basement and garage. They should be placed within 10 feet of each bedroom door to ensure the alert is heard during the night when everybody is sleeping. All detectors should be attached to the wall or ceiling so they are permanent fixtures and always primed and ready to sound the alarm.

Battery and/or Wiring Upkeep

Your carbon monoxide detector must be working at all times. Replace batteries twice a year, at least. You can test your detector periodically by pressing the front button. If your unit is malfunctioning, replace it immediately. Detectors have a life expectancy of around five years, so replace them accordingly.
