How to choose

  1. Define the job: Is it odor control, general maintenance, or recovering from heavy use?

  3. Mind your water use: Spread laundry and showers; treatments work best with moderate flow.
  4. Combine with good practice: Avoid antibacterial cleaners down drains; don’t flush wipes; pump on schedule.
