Sigma cares about your safety. In the event a blockage of the
pump suction line occurs - The Safety Suction Sensor will
instantaneously shut off pump. This sensor is placed on the
intake pipe of whirlpool system and connected to Electronic
Bath Controller and operates automatically.

We also offer optional Water Level Sensor. This option will not
let your pump start until water level is above all jets. This
option gives you added safety from little ones or people
unfamiliar with whirlpool systems accidentally turning on
system before bath is full and splashing water out of tub or
prolonged dry running of pump.

These options are only available with Electronic Pump and
Light Controller.
