38mm Double Button Toilet Tank Flush Control for One-Piece Toilets

This toilet tank accessory is a specified replacement part for the flushing mechanism of one-piece toilets. It is designed to work with toilets that utilise a hand-press control method and ground drainage system, providing a practical solution for maintenance or part renewal. The core component is a 38mm round double push-button made from ABS plastic, offering a direct swap for existing broken or worn-out buttons. This product focuses on delivering a single, concrete specification—the 38mm button size—within a compatible flushing assembly.
Features and Construction

This accessory is defined by its specific role within a toilet cistern's operation. The available information centres on its material and its primary flushing control specification.
Material and Build
The button mechanism is constructed from ABS (Acrylonitrile Butadiene Styrene) plastic. This is a common thermoplastic used in various consumer and industrial products, known for its strength, rigidity, and resistance to corrosion, which makes it a practical choice for components frequently in contact with water. The build is tailored to function as part of a hand-operated flushing system, activating the toilet's siphon or flush valve to release water.
Size and Practical Fit
The key measurable specification provided is the 38mm diameter of the round double push-button. This dimension is critical for ensuring compatibility with the existing aperture in the toilet tank lid or front panel. It is designed specifically for one-piece toilet models, which integrate the tank and bowl into a single unit, and for systems that employ ground drainage. Users should verify their current mechanism uses a similar 38mm double-button design before purchase.
Uses and Placement

This product serves a clear, replacement-focused function within residential and commercial bathroom settings. Its application is tied directly to the technical specifications provided.
Event or Professional Use
For property managers, maintenance technicians, or plumbing professionals, this part offers a standardised component for repairing the flush control on compatible one-piece toilets. Its 38mm size and ground drainage compatibility make it a straightforward stock item for fixing toilets where the push-button has failed, avoiding the need for a full cistern replacement.
Everyday Home Use
Homeowners or tenants facing a faulty flush button on their one-piece toilet can use this accessory as a direct replacement. The double-button design typically allows for a full flush or a partial flush, helping to control water usage. Installation generally involves accessing the toilet tank and connecting the new button mechanism to the existing flush valve linkage.
Benefits and Buying Value

The value of this product lies in its specificity and functional replacement role, supported by the concrete data available.
Reuse and Low Maintenance
By replacing just the flush control mechanism, this accessory extends the life of the existing toilet cistern. It is a more economical and less wasteful solution than replacing the entire toilet or cistern assembly when only the button is faulty. The ABS material is chosen for its durability in a damp environment, requiring minimal upkeep once installed.
Why Choose This Product
This product is selected for its exact match to the given specifications: a 38mm double push-button for hand-press, ground drainage, one-piece toilets. It avoids guesswork by providing a single, confirmed measurement and material. It is a purposeful component for repair, not a universal fit, making verification of your existing toilet's mechanism the essential first step before purchase.
