The product shown is a flexible toilet pan connector featuring an integrated non-return valve (also known as an anti-snake or backflow preventer valve). It is designed to bridge the gap between a toilet's rear outlet and the main soil pipe, especially in situations where standard rigid pipes cannot be easily aligned.

Key Features and Functionality

Backflow & Pest Prevention: The core feature is a built-in flap or non-return valve. This valve automatically opens when water is flushed and closes immediately after to prevent sewage backflow, foul odors, and pests—such as snakes, rats, and cockroaches—from entering the bathroom through the drain.

Flexible Construction: Made from durable materials like PVC, ABS, or high-density polyethylene (HDPE), the pipe has a "slinky" or harmonica-style design.

This allows it to extend, contract, and bend to accommodate unconventional angles or offset plumbing.

Leak-Proof Seals: It typically features multi-finned rubber seals at the ends to ensure a watertight and airtight connection to the toilet pan and the 110mm standard waste pipe.Ease of Installation: It is designed for quick, tool-free installation, making it suitable for residential homes, apartments, and commercial restrooms.
