Concealed Toilet Flush Plate Hydroland under-wall syphon, white

Concealed Toilet Flush Plate Hydroland under-wall syphon in white is a hidden drainage solution designed to be installed behind drywall or within a service wall. Manufactured by Hydroland, this under-wall syphon connects a toilet outlet to the waste system discreetly, providing a compact and concealed channel for wastewater. The white finish matches common sanitary ceramics and bathroom fixtures, enabling a visually cohesive installation for both wall-hung and close-coupled toilets that require a hidden trap or syphon.

Advantages

The concealed design reduces visible plumbing and saves room in the bathroom by locating the syphon inside the wall cavity. Its white finish provides a neutral appearance that integrates with standard sanitaryware and interior finishes. The unit is suitable for both residential and commercial installations and supports a neat, low-profile installation that simplifies cleaning and maintains a consistent bathroom aesthetic.

Suitable for

• Wall-hung toilets requiring a hidden syphon or trap
• Close-coupled toilets where an under-wall connection is preferred
• Bathrooms with drywall or service walls that conceal plumbing
• Residential and commercial sanitary installations seeking a discreet drainage solution
