Green Drain Floor Drain Trap Seals
Floor drains can become a source of unpleasant odors and pest problems when traditional drain traps dry out or fail to maintain an effective barrier. Green Drain provides a waterless trap solution designed to create a physical barrier inside the drain while still allowing water to flow through.
Unlike chemical drain treatments, Green Drain does not rely on chemicals to create the barrier. The system uses a one-way sealing mechanism that allows water to pass through while helping prevent odors, sewer gases and pests from traveling back through the drain outlet.
This makes Green Drain a useful option for commercial buildings, restaurants, food-service facilities, warehouses, manufacturing facilities, healthcare environments and other locations where floor drain odor and pest control are important parts of facility maintenance.
A Waterless Alternative for Floor Drains
Green Drain is designed to act as a waterless trap for compatible floor drains. It provides a physical barrier rather than requiring regular chemical treatment or the addition of water to maintain a traditional trap seal.
How Green Drain Works
The Green Drain system uses a one-way valve and sealing components installed inside a compatible drain outlet. Water can flow downward through the drain, while the closed sealing mechanism helps prevent unwanted materials from traveling upward through the drain.
Water Flows Down
Water is allowed to pass through the drain during normal drainage.
Creates a Barrier
The sealing mechanism creates a physical barrier within the drain outlet.
Helps Block Odors
The closed trap helps prevent unpleasant drain odors from traveling back through the outlet.
Helps Block Pests
The physical barrier helps deter insects and other pests from entering through the drain.
Green Drain Helps Address Common Drain Problems
Drain Odors
Help prevent unpleasant sewer and drain odors from entering occupied areas through floor drains and compatible drain outlets.
Pest Infiltration
The physical sealing mechanism helps prevent insects and other pests from traveling through compatible drain openings.
Sewer & Drain Gases
The waterless trap provides a barrier intended to help prevent sewer and drain gases from entering through the drain outlet.
Drain Maintenance
Green Drain provides an alternative to maintaining a traditional water seal through regular additions of water or chemical drain treatments.

Verify Your Drain Size Before Ordering
Green Drain products are size-specific. Measure the compatible drain connection and verify the required Green Drain model before ordering. The current UnoClean listing is for the 4-inch Green Drain Floor Drain Trap Seal.
Green Drain Floor Drain Trap Construction
Green Drain's inline floor drain trap seal uses several components to create its waterless barrier. Manufacturer information describes the system as using a UV-resistant ABS plastic housing, a silicone rubber sealing flapper and four flexible sealing ribs.
ABS Plastic Housing
The trap seal uses a UV-resistant ABS plastic housing designed for installation inside compatible drain systems.
Silicone Sealing Flapper
A silicone rubber sealing flapper forms the primary one-way barrier inside the trap.
Flexible Sealing Ribs
Four flexible sealing ribs help secure the trap seal within the compatible drain housing.
Green Drain Installation
Green Drain is designed to provide a relatively simple installation process in compatible drain outlets. Manufacturer information states that installation does not require caulk or expensive installation tools.
1. Identify the Drain
Determine the drain type and connection size before selecting a Green Drain trap seal.
2. Select the Correct Size
Choose the Green Drain model that corresponds to the compatible drain opening or housing.
3. Install the Trap Seal
Insert the Green Drain unit into the compatible drain housing according to the manufacturer's installation instructions.
4. Verify Operation
Confirm that water can flow through the drain while the sealing mechanism remains properly positioned.
5. Remove When Necessary
The manufacturer states that the Green Drain unit can be removed without requiring pliers or specialized installation tools.
Green Drain for Commercial Facilities
Commercial facilities often have numerous floor drains located throughout kitchens, restrooms, utility rooms, mechanical areas, production spaces and other areas. Maintaining effective drain barriers can be an important part of facility maintenance and odor-control programs.
Restaurants & Food Service
Use compatible drain trap seals in commercial kitchen and food-service areas where drain odors and pest infiltration can create maintenance concerns.
Commercial Buildings
Help address odors from floor drains in offices, retail buildings, public facilities and other occupied commercial spaces.
Industrial Facilities
Waterless drain traps can be considered for compatible drains in warehouses, manufacturing facilities and other industrial environments.
Healthcare Facilities
Drain barriers can be incorporated into appropriate facility maintenance programs where floor drain odors and pest infiltration are concerns.
Hotels & Hospitality
Help manage drain-related odors and pest infiltration in compatible drains throughout hospitality properties.
Facility Maintenance
Provide maintenance teams with a physical drain-barrier option that does not depend on routine chemical treatment.
Green Drain vs. Traditional Drain Treatments
Green Drain addresses drain problems differently from chemical drain treatments. Instead of adding a chemical product to the drain, the Green Drain system creates a physical barrier within the drain outlet.
