What I would recommend is the single most important thing is to have your tank pumped regularly. We recommend between three to five years, depending on the members in the household. Not pumping your tank regularly is the single biggest cause for system failures down the road. Always go out and make sure that your, the job was done correctly and your tank was completely pumped to where you can see the bottom of the tank.
The single most important thing to maintain a septic system is have the tank pumped regularly. The recommended times are usually between three to five years. This ensures that the solids from the tank don't make their way to the leach lines, lessening the life of your leach line. While doing that, you can also have a septic system filter installed on the outlet, which keeps any residue from getting out into the leach lines as well.
