Prevents odorous gas in plumbing drains and sewers from rising up through a sink into a home or business.

Features:

• By drawing air through the valve, the Silentrap neutralises syphonic pressure before it reaches the seal of the trap and therefore provides the equivalent of a ventilated system without the installation of costly and unsightly ventilation pipes.
• The Silentrap has been most rigorously tested and will not unseal, even under the most abnormal conditions.
• The Silentrap should continue to be effective irrespective of the distance between the appliance and the soil pipe.
• The major advantage of the Silentrap over Resealing Traps is that because the air is drawn through the valve and not through the water seal, gurgling is eliminated and a much quieter discharge is ensured.
• Eliminates the need for secondary ventilation.
• Silentraps allow for greater flexibility in plumbing design.
• 75mm Water seal.
• 1½" Universal compression outlet suit all plastic, copper, and lead pipe.
