Infra-red Dual Flush


Sensor Operated Dual Flush WC Valve with Manual Override

3 OR 4 STAR WELS Options available

#ET4-7.4 (4-star WELS)
#ET4-7.3 (3-star WELS)

A cost effective mains water pressure infra-red toilet flush valve with a simple stainless steel face plate. It is suitable for all public toilets, schools, stadiums, hospitals, bars, theatres and churches.

Installation of this flush valve removes the need for concealed cisterns and eliminates the associated costs of their installation and maintenance. The valve box is simply installed in-wall with easy access to the valve through the front face plate for maintenance.

Once installed, only the face plate is visible in the bathroom, it is a very neat solution. Also features a manual override button for when enhanced user comfort is required.

Particularly suitable for high use areas, such as Service Stations, Malls and Stadiums as there is no cistern to re-fill between users.
