Frequently Asked Questions

Q: What pipe sizes does this silicone drain trap sealing ring fit?

A: The elastic silicone construction makes this sealing ring compatible with a wide range of pipe sizes, including 16mm air conditioning condensate drain pipes, 25mm washing machine drainage pipes, and 32mm basin/sink drain pipes. The silicone material can also be carefully trimmed to accommodate other non-standard sizes.

Q: How does the anti-odor mechanism work?

A: The sealing ring uses a dual-barrier system: a built-in silicone inner ring physically blocks sewer gases from traveling back up through the pipe, while a magnetic outer seal closes automatically when not in use to prevent insects and odors from entering. The one-way valve allows water to drain freely while staying closed when dry.

Q: Is this difficult to install?

A: Not at all! This is a true plug-and-play accessory. Simply slide the silicone sealing ring over or into your existing drain pipe — no tools, glue, or plumbing experience required. It works for vertical floor drain installations, angled side-wall setups, and horizontal 90° wall drain configurations.

Q: Can I use this with a water purifier?

A: Yes! The sealing ring includes a pre-made small hole designed specifically for routing a water purifier return pipe. Simply insert the return line through the hole for a neat, integrated connection without any additional modifications.
