I don't know where you all have been.

Sinks / tubs that have no overflow have an ultrasonic depth computing device UDCD mounted above the unit that computes when the unit is too full and fires a solenoid that secures the water supply.

These UDCD must be checked during a HI as a mater of SOP - check the last up date
