Anti-Syphon Traps (Silentrap)

Anti-syphon traps (Silentrap)

General

  • 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

Operation

Whenever syphonic conditions develop, the negative pressure causes the Valve to rise, allowing air to be drawn into the discharge pipe. The pressure is thereby neutralised before it can have any effect on the water seal within the Trap. On cessation of the syphonic action, the Valve closes, making the Silentrap air and watertight

Advantages

  • 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
  • Silentrap Valves are available on a wide range of Bottle, Tubular and Bath Traps
  • Silentraps allow for greater flexibility in plumbing design

The products below simply show that the Silentrap Attachment is available on Bottle, Tubular and Bath Traps.

Multifit Connections

Multifit Connections

  • Most McAlpine Trap Outlets and Fittings have Multifit Connections.
  • Multifit Connections suit 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.
  • For technical reasons, it is not possible to manufacture Multifit Connections on all traps and fittings. Where Multifit is not provided the description Universal is applied. The only difference being that Universal does not have an Internal Sleeve within the Trap or Fitting.
