Plumbing vent pipes are critical components of a septic system that serve as escape points for septic tank odors and gases. When these are too low or displaced, there’s a likelihood of smells hanging in the air.

This is an uncomfortable situation that can be addressed by extending your plumbing vent pipes further out.

Doing so allows for more efficient dispersal of odors.

  • Installation of Carbon Filter

Activated carbon filters are products designed to neutralize or remove offensive septic tank odors such as hydrogen sulfide. This happens as such gases exit the sewer vents.

Carbon filters are usually installed at the top of the plumbing vent.

  • Running a Few Flushes

If you’ve been absent for a significant period of time, chances are that the water barriers designed to block out gas and odors will be dried out. This causes your home to smell awful. Thankfully, this problem can be resolved easily.

All you need to do is run a few flushes across all toilets.

An experienced plumber will get the job done much effectively.

  • Properly Securing Septic Manholes and Risers
