We strongly recommend that you retain the services of a licensed septic service professional to install your SepticSitter sensors. This is for safety reasons but also to ensure the sensors are installed in a location and at a depth that will be the most beneficial for monitoring your septic system. Tanks contain hazardous gases and sewage contains hazardous bacteria and viruses. Septic professionals are trained and experienced on how to work around septic systems safely. For warranty coverage, the system must be installed by a licensed septic service professional.
