Sweep the area around the blower to keep dirt, grass clippings and other debris away from it. Depending on the design and manufacturer of your specific septic system, the blower is typically on top of a concrete pad over the septic area.
Check each sprinkler in your yard for any sign of physical damage. Remove any heavy objects nearby that may damage it, such as hanging tree branches.
Unscrew the air filter on top of the blower. Remove the air filter and rinse it out with a garden hose. Avoid using any type of detergent, unless otherwise specified by the manufacturer. Replace the filter and the screws.
Pull up the effluent filter from its base. Depending on your specific system, the effluent filter is usually located next to the main access lid. You will likely need to remove the cap on the effluent access to pull up the filter. Rinse off the effluent filter and replace it. Clean the filter at least once a year.
Pull up the chlorine dispenser tube from the chlorinator. Rinse out the tube to remove any residue and old chlorine tabs. Add the number of new chlorine tabs recommended by the manufacturer or state law. Replace the tube carefully; never drop it. Contact the manufacturer if you are unsure how to locate the chlorinator tube. It's typically near the main access port.
