Springwell Smartflush stands by until movement is detected, then waits before filling and flushing the cistern.


To obtain the best economy while maintaining a good standard of hygiene, the operating cycle ends in a flush, so that urine is never held in the trap for longer than the cycle time (default 30 minutes) thus minimising the risk of developing unpleasant smells while using only one cistern full of water in the cycle.
When optimally set up, the cistern should be empty between flushes. When a fill occurs, the cistern should fill and flush and the valve should turn off during the flush, hence the cistern will usually remain empty. With a typical fill time of 3 minutes and a cycle time of 30 minutes the unit will appear to be 'not working' for 27 out of every 30 minutes even at busy times, so the chance of seeing any activity on a spot check is remote. Minor fluctuations in water pressure are allowed for as the unit will remain "in step" as long as the valve turns off sometime during the emptying of the cistern, because the cistern always empties to the same low level.

The controller may be fitted either to ceiling or to wall (as long as the controller is visible to users) as the sensor is quite sensitive. Be aware that automatic scent devices may trigger a cycle if the scent vapour passes close to the sensor.
