Toilet tank accessories one-piece toilet round double flush button for hand press operation, 38mm specification ABS plastic flush valve button designed for ground drainage systems
38mm ABS Plastic Double Flush Button for One-Piece Toilet Tanks

This toilet tank accessory is a specific replacement part for one-piece toilets utilising a ground drainage system. The 38mm round double button, operated by hand press, is moulded from ABS plastic and is supplied as a single unit. It is designed for homeowners or maintenance personnel needing to restore the flushing mechanism on compatible toilets without replacing the entire cistern. This product addresses a common point of failure in bathroom plumbing, offering a straightforward fix.
Features and Construction

This flush button is defined by its specific measurements, material choice, and intended application. It is not a universal fit but a targeted component for particular toilet models.
Material and Build
The button is made from ABS plastic, a material selected for bathroom accessories due to its rigidity and resistance to the humid environment. It is moulded into a round shape with a double-button design for flush control. The construction is focused on providing a reliable surface for repeated hand presses without the material degradation that can affect less suitable plastics.
Size and Practical Fit
The crucial specification is the 38mm size, which refers to the diameter or fitting size of the button assembly. This measurement must match the aperture in your toilet tank lid for a correct installation. The product is engineered for one-piece toilet designs, meaning the cistern and bowl are formed as a single unit, and is compatible with ground drainage flushing systems.
Uses and Placement

This accessory has a single, clear purpose: to replace a broken or worn flush button on a compatible toilet. Its use is confined to residential bathrooms, maintenance jobs, or specific commercial settings with matching toilet fixtures.
Event or Professional Use
For property managers, landlords, or plumbing professionals, this part serves as a standard inventory item for quick toilet repairs. Keeping a correctly specified button like this 38mm ABS model can minimise downtime for a tenant or customer, as it allows for a swift cistern lid replacement without needing a full toilet service.
Everyday Home Use
For the householder, this product solves the problem of a toilet that won't flush because the button is stuck, cracked, or has failed. It enables a DIY repair that can often be completed with basic tools, restoring full functionality to the toilet and avoiding the cost of a call-out for a simple part replacement.
Benefits and Buying Value

The value of this product lies in its specificity and the practical solution it provides for a common household issue.
Reuse and Low Maintenance
By replacing just the button, you extend the life of the existing toilet tank, supporting a repair-over-replace approach. The ABS plastic material requires minimal maintenance; keeping it clean from limescale or dirt build-up with occasional wiping is typically all that's needed once installed.
Why Choose This Product
Choose this product if you have identified a 38mm flush button as the faulty component on your one-piece, ground-drainage toilet. Its value is in being the correct, direct replacement part. It offers a cost-effective and timely solution compared to sourcing a generic part that may not fit or opting for a more complex repair.
