Important: Please check your measurements carefully before ordering to ensure the correct size is selected. Returns cannot be accepted for items that may have been exposed to grey water or sewage, so confirming the drain size before purchase is essential.

The Green Drain Waterless Trap Seal 2.5" is a highly effective solution for sealing floor drains without the need for a traditional water trap. Designed to sit inside the drain, it forms a one-way barrier that helps block foul odours, sewer gases, insects, and contaminants, while still allowing water and debris to flow freely. This 2.5" model suits drain openings from 55-65mm, making it ideal for mid-sized floor drains in residential, commercial, and industrial environments.

Constructed from UV-resistant ABS plastic and fitted with a flexible silicone membrane, the Green Drain delivers reliable, long-term performance. Its four flexible sealing ribs ensure a snug fit even with slight variations in pipe size, while the membrane opens during water flow and closes when idle to maintain an effective seal. With a compact 35mm height and a flow rate of 72.50 LPM, it provides strong drainage performance without compromising protection.
