High Standard of Hygiene

Unlike hydraulically-operated urinal valves, the SmartFlush urinal valve is designed to flush within a short time of every use, typically no more than 30 minutes, so the urinal stays fresher for longer.

Fast filling ensures that the cistern gives a proper urinal flush, avoiding the constant trickle out which sometimes happens with trickle-fed cisterns.

Cycle time may be adjusted at any time to 20, 30, 40 or 60 minutes.

Cycle time, from triggering to the end of the flush, may be set to 20, 30, 40 or 60 minutes.

Fill time, up to 31 minutes, is easy to set. In standby, a Maintenance Flush occurs every 8, 12, or 24 hours, timed from last flush.

Smartflush waits until movement is detected, then delays before filling and flushing the cistern.

How Smartflush Works

The PIR can be fixed anywhere to give optimum detection - on the ceiling or the wall

The Springwell battery pack is guaranteed to last no less than 3 years. When the battery does get low the controller will look for movement and tweet when a person has been detected.

The SF4 controller features a 5 level battery state indication activated by holding the hidden button.
