Non-return valve, adjustable silicone sink siphon, suitable for bathroom and kitchen plumbing pipes (blue 4)

Suitable for standard pipes from 1.5 cm to 1.75 cm. Please measure the pipe you intend to use before purchasing to ensure you buy the correct floor drain. Two fixing rings are included to accommodate different pipe sizes. The automatic shut-off design prevents wastewater from generating odors and tastes, stops sewer backflow, and facilitates drainage. Installation is very simple; just insert it directly into the drain pipe. If the silicone section is too long, you can trim the flat end for faster drainage. The floor drain is made of high-quality, eco-friendly silicone, which is durable and stretchable, so there's no need to worry about deformation and is super flexible. Suitable for most toilets, bathrooms, kitchens, basements, and washing machine drains. After installation, there will be no more odors in the room. Enjoy fresh air and a better life.
