Features and Construction

The core of this accessory is its 38mm flush button assembly. This section details its material build and how its size ensures a practical fit for standard cisterns.
Material and Build
The flush button is made from ABS plastic, a material chosen for its strength and resistance to moisture in bathroom conditions. This construction provides a rigid interface for repeated manual pressing without degrading, focusing on longevity through its material properties rather than invented performance claims.
Size and Practical Fit
With a specified diameter of 38mm, this button is designed to fit standard apertures in one-piece toilet cisterns. This precise measurement ensures it acts as a direct replacement part, eliminating guesswork for installers seeking a compatible manual press flush mechanism.
Uses and Placement

This product serves a specific function within domestic plumbing. Its use is defined by the toilet's design and drainage method.
Professional or DIY Installation
The kit is suitable for both professional plumbers and competent DIY homeowners replacing a faulty flush button. Its compatibility is clearly stated for one-piece toilets with ground drainage, providing a clear guideline for appropriate use.
Everyday Home Maintenance
In a domestic setting, this part allows homeowners to restore a toilet's flushing function. The dual-button design supports everyday water conservation efforts by offering a choice between partial and full flush volumes.
Benefits and Buying Value

The value of this accessory lies in its specificity and completeness as a replacement part, avoiding the need for a full cistern replacement.
Reuse and Low Maintenance
By replacing just the flush mechanism, the existing toilet cistern and bowl can continue in use. The ABS plastic construction requires minimal maintenance, needing only occasional cleaning like the surrounding bathroom fittings.
