Safety first
Available in 

Designed for gas boilers, the pressure safe system allows a safe discharge of condensates and pressure release valve water.
The pump Si-1800 collects condensates and pressure release valve water. A diffuser reduces the pressure of the water discharged in the pump. If a failure occurs, the pump sends a signal to a regulation box.  The regulation box then closes the solenoid valve and stops cold water from entering the boiler.
