⚡ At a Glance
- • Flush Performance: Dual 3L/6L flush volumes, internal overflow and cable operation
- • Best for: Homeowners and plumbers doing cistern retrofits and replacements
- • Not ideal for: Cisterns with non-standard or electronic integrated flush systems
Cable-operated dual flush valve fits 1.5in and 2in outlets and 20-60mm push-button holes. WRAS-approved with internal overflow for compliant retrofit installations.
Reduced water use – thanks to 3L/6L dual flush
Two selectable discharge volumes assign a smaller 3 litre flush for liquid waste and a larger 6 litre flush for solids, controlled by the push-button mechanism. Internal overflow prevents surcharging by routing excess water safely.
Lower water consumption on routine flushes helps cut household usage. Practical savings accumulate over time without changing user habits.
Broad cistern compatibility – with 1.5in and 2in outlet fittings
Designed to accept either 1.5in or 2in outlet connections and compatible with cistern hole diameters from 20-60mm, supplied outlets match common cistern standards. Includes parts for adapting to the two outlet sizes as noted by users.
Simple retrofit to a wide range of cisterns avoids the need for full replacement. Fewer parts to buy makes installation quicker for tradespeople and DIYers.
Easy cable-operated installation – with a 300mm control cable
A 300mm cable connects the push button to the valve, enabling external button placement and straightforward mechanical actuation. Cable operation suits closed-coupling cisterns and standard push-button layouts.
Rapid swap-over installation reduces time on site and hassle for homeowners. Reliable mechanical action gives consistent performance with minimal adjustment.
