McAlpine 75mm Water Seal Straight Through Anti-Syphon (Silentrap) Trap With Cleaning Eye & Multifit Outlet 1¼"

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

Features:

• 1¼" Inlet and outlet.
• 75mm Water seal.
• Inlet and outlet connections are directly in-line allowing for neat plumbing behind basin pedestals.
• Includes cleaning eye.
• 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.
• 1¼" Multifit compression outlet suits all plastic waste pipes to BS EN 1451-1-2000 and BS EN 1329-1:2000, copper pipe (metric or imperial) and lead pipe.
• The moulded internal sleeve of the connection, centres and supports the pipe.
• The Multifit and friction washers ensure a secure seal is made between the pipe and the wall of the fitting.
• When the compression nut is turned hand tight the best possible mechanical joint is complete.
• If a plastic pipe is undersize, or out of shape, the end may require to be warmed to enable it to be pushed over the internal sleeve.
