Who it fits
Good fit for
This disposal suits homeowners with septic systems who want a unit that actively supports waste digestion. The included Septic Guard liquid helps break down food buildup in pipes. DIYers will appreciate the EZ Connect Hardwire Adapter and Lift and Latch technology, which streamline the installation process without professional help. It is also a good fit for those seeking quieter operation through SoundSeal technology and a fresh citrus scent to reduce kitchen odors.
Who should skip it
You should look elsewhere if you need a corded power connection, as the EZ Connect Power Cord is sold separately. This model is designed for hardwiring, so it may not suit renters or those who prefer plug-in convenience without additional purchases. If you do not have a septic system, the specialized Septic Guard liquid may be unnecessary. Additionally, the BOOST accessory is included, but if you only need the basic disposal without the dishwasher adapter, consider the variant that excludes it to save space and complexity.

Key specs for this disposal

Septic Guard liquid formula
This included liquid helps break down food solids in your plumbing system. It is designed to support the digestion of waste in septic tanks and pipes. The formula is non-corrosive, so it protects your plumbing components. If you have a septic system, this additive can help prevent buildup and maintain flow.

Things To Check Before Buying
Before you buy this unit, verify your sink opening size. The 8.25-inch width fits most standard setups, but measure your cabinet depth first. You must purchase the EZ Connect Power Cord separately if you prefer plug-in wiring over hardwiring. The included BOOST accessory attaches to the dishwasher inlet, so confirm your dishwasher hose diameter matches the adapter. If you live on a septic system, the included Septic Guard liquid supports waste digestion. You need to refill this solution periodically to maintain odor reduction and system health.

Check local codes for hardwiring requirements. This model suits households that generate moderate food waste and want quieter operation. It is not for heavy commercial use. Compare its compact footprint against larger units if space is tight. The gray finish matches standard kitchen hardware. Keep the Septic Guard liquid within reach for monthly maintenance.
