Hydraulic safety group are safety device that limits the pressure in hot water heaters, prevents the backflow of water into the main circuit, prevents the discharged water from coming into contact with the water in the water heater, allows the function of the backflow prevention to be controlled and isolates and drains the water heater for maintenance services. BS EN 1487 is a European Standard that
