• The need to pour pesticides, chemical applicants and deodorizers down the drain.


• Water and water related expenses by eliminating the need for trap primers.
• Time and energy.


• The risk of harmful sewer gasses intruding your facility through drain lines.
• Costly chemical expenditures.
• Plumbing related call‐outs.
• Exterminator related call‐outs and call‐backs.
• Timely drain maintenance by Facility Staff and Plumbers.
