Viva Sanitary Skylo Universal Push Button — UNI/SB
The Viva Sanitary UNI/SB is an authentic replacement dual-flush push button assembly designed specifically for the Viva Skylo flush valve and drop valve ranges. Finished in a mirror-polished chrome coating, this universal button assembly solves lid sizing issues by including spacer collars to fit standard 40mm, 50mm, and 60mm cistern lid apertures. Driven by an adjustable central mechanical linkage, it provides crisp, independent dual-flush actuation for both partial and full flush settings.

Installation & Compatibility Note
Designed strictly for Viva Skylo flush and drop valves. This is a top-mounted mechanical push button (not suitable for cable-operated or pneumatic systems). Measure your cistern lid hole diameter to select whether the button requires the standard body (40mm) or the included snap-on outer collars (50mm / 60mm). Adjust the actuation rod beneath the button so it lightly contacts the flush valve lever without depressing it while at rest.
