Los Angeles Septic Certification

         A septic certification is a document stating that an inspection has been performed on a septic system and is deemed to be functioning properly with all system components up to code. An inspected system will either pass or fail, depending on the condition of the system itself and whether or not said system meets the required list of guidelines necessary for a proper certification approval.
