Do you have a filter in your septic system? If you have a newer system, you will have a filter on the outlet baffle of your septic tank.
What does a filter do for my septic system? Filters prevent solids from leaving the septic tank and entering your septic bed. If solids enter your septic bed from the tank, there is the potential for them to accumulate and cause a failure of the bed (and contents from the tank may eventually back up into the house).
What maintenance is required for my filter? It is important that the filter is cleaned annually to remove any build up of solids that is preventing liquids from entering the septic bed.
Cleaning a filter is simple - just rinse it out with a garden house!
This picture shows a clogged effluent filter that requires cleaning. If the liquids cannot enter the septic bed, a back up of the contents of the septic tank into the house may occur.
