Sewer Gas Detector

A sewer gas detector alerts the user to dangerous gases when working around drains. Typically used by home inspectors, plumbers, or anyone who may be exposed to hazardous sewer gases. The most common gasses found in the sewer system are Hydrogen Sulfide, Ammonia, and Carbon Dioxide. These are produced by the decomposition of waste in sewer systems and can enter homes through leaks, clogged vents, or broken pipes. Our Crowcon T4 multi-gas monitor detects all four of these along with oxygen, allowing the user to remain safe in any confined space.

Leaks in the plumbing system itself: The most obvious sign of a sewer leak is the rotten egg smell that comes from your drains. The best way to check your home for this is to visually inspect all of your drains and plumbing fixtures for any signs of a leak. Your pipefitter can also perform a test known as the “smoke test” by blocking all of your drain vents and then blowing smoke through the system. The areas where you see smoke will indicate where the leaks are occurring.

The Silent Threat: Why Every Home Needs a Sewer Gas Detector

The other way that a sewer leak can get into your home is through the vent line that runs from the sewer line to the roof and exterior wall. This can occur when there is a hole in the vent pipe, a loose fitting, or corrosion. Our pipefitter will often recommend relining the vent line with non-corrosive material to prevent future problems.
