SeptiFlush™ — A self-cleaning, reverse-flush septic effluent filter system designed to be serviced without opening the septic tank.

On-site wastewater treatment, specifically effluent filtration for residential and commercial septic systems, including retrofit and OEM-integrated outlet filters with externally accessible cleaning ports.

Conventional septic outlet filters protect leach fields from solids carryover, but require periodic manual cleaning: opening the tank lid, extracting a soiled cartridge, and spraying it down. The process is unpleasant, exposes the operator to effluent, and is frequently skipped by homeowners — leading to clogged filters, backups, or leach-field damage.

SeptiFlush™ is a concept for a septic effluent filter assembly with an external service port. A homeowner or technician connects a standard garden hose, opens an isolation valve, and water is routed through internal channels to spray jets that reverse-flush accumulated debris off the filter media back into the tank — without removing the filter or opening the lid.

• External hose connection port (above-grade)
• Isolation / shutoff valve
• Internal reverse-flush tube routed to filter housing
• Spray-jet manifold positioned around filter media
• Backflow / check-valve assembly
• Standard or retrofit-compatible filter cartridge

1. Operator connects garden hose to the external service port.
2. Operator opens the isolation valve.
3. Pressurized water flows through the internal reverse-flush channel.
4. Spray jets clean the filter media in place; debris falls back into the tank.
5. Operator closes the valve and disconnects the hose.

• Pump-driven flush using tank effluent in place of fresh water.
• Compressed-air assisted purge for solids dislodgement.
• Multi-stage filter with sequential jet zones.
• Sensor-equipped variant reporting flush cycles and filter loading.

A retrofit kit could replace the existing outlet filter housing on common residential septic tanks, routing a small-diameter line up through an existing inspection riser to a discreet external port.

In an automated embodiment, a low-voltage controller would trigger scheduled or load-based flush cycles using a solenoid valve, with optional remote monitoring of filter condition and flush history.

Any potable-water connection requires appropriate backflow protection (e.g., vacuum breaker or RPZ assembly) per applicable plumbing codes. Final design is subject to engineering validation and local code review.
