When the trap is subject to syphonic conditions the automatic hydraulic action allows air to be drawn through the inlet of the trap and through the by pass columns thus breaking the syphonic action. On cessation of syphonic conditions the remaining water falls back to reseal the trap.
The Silentrap ventilates by drawing air through a non-return valve whereas the Resealing Trap ventilates by drawing air through the inlet of the trap and through the water seal
■ The simple non-mechanical action ensures retention of adequate water seal even under extreme syphonic conditions
■ Eliminates the need for secondary ventilation
