V1 — Manual Reverse-Flush Prototype
External hose port, isolation valve, and an internal reverse-flush tube feeding a simple spray manifold around a standard outlet filter cartridge. Goal: prove the core cleaning action without removing the filter.

Prototype Development
Working notes on the SeptiFlush™ prototype path — from first 3D-printed form studies through production-intent materials, backflow validation, and spray-jet testing.
V2 — Integrated Filter Body
Filter housing and reverse-flush manifold combined into a single molded body, with an integrated check valve and a standardized riser-mounted service port.
V3 — Automated Flush System
Low-voltage solenoid valve, controller, and optional load sensor to schedule or trigger flush cycles automatically, with future hooks for remote monitoring.
Materials Under Review
PETG for form studies, ABS/ASA for intermediate prints, and PVC/HDPE for any component intended for extended in-tank service. Selection is preliminary and subject to chemical-compatibility and longevity testing.
3D Printing Notes
- Thicker walls and higher infill on pressurized channels.
- Threaded port inserts to avoid stripping plastic threads.
- Print-orientation tuning for nozzle/jet features.
Testing Plan
- Dry-fit and leak test of hose port and isolation valve.
- Bench flush of representative soiled filter media.
- Backflow / vacuum-breaker validation per applicable plumbing code.
- Cycle testing for long-term durability of in-tank components.
Known Engineering Questions
- Optimal jet count, angle, and pressure for consistent media cleaning.
- Long-term material compatibility with septic effluent and gases.
- Best riser/lid integration path for retrofit installations.
- Code-compliant backflow approach across jurisdictions.

Prototype Hardware Cards
Snapshot of the materials and test rigs currently in or near the workbench.
PETG Prototype
Initial form-and-fit prints to validate port geometry, hose-thread fitment, and internal channel routing. Not intended for pressure or chemical durability testing.
ABS/ASA Prototype
Second-pass prints targeting better impact resistance and UV stability for above-grade service-port components and short-duration pressure trials.
PVC/HDPE Production Concept
Production-intent materials. PVC for fittings and housings, HDPE for in-tank components, aligned with common septic component supply chains.
Check Valve / Vacuum Breaker Testing
Backflow prevention is mandatory for any potable-water connection. Evaluating off-the-shelf vacuum breakers and integrated check-valve placements.
Spray Jet Pattern Testing
Bench testing nozzle count, angle, and pressure drop to verify uniform reverse-flush coverage across representative filter media.
