Know before you buy
Yes, the Evolution Septic Assist is specifically engineered for septic systems. It features a two-stage grinding process that breaks food waste into finer particles, which helps the septic tank process the material more effectively.
No, the power cord is not included with this unit. You will need to purchase one separately or hardwire it directly to your electrical supply during installation.
A continuous feed disposal allows you to add food scraps into the unit while it is running. You simply keep the water flowing and the disposal on until the grinding sound stops, making it very convenient for cleaning up after meal prep.
This model is designed for remarkably quiet operation. It uses advanced sound-dampening technology to minimize noise, allowing you to carry on a conversation in the kitchen while the unit is running.
The unit is equipped with built-in anti-jam technology to prevent blockages during normal operation. Additionally, it includes overload protection that will automatically shut off the motor to prevent damage if a significant obstruction occurs.
This specific model does not feature a dishwasher drain connection. You will need to ensure your dishwasher drains through a separate plumbing line or consider a different model if a direct connection is required.
