CP Basin Kit with Plastic Tubular Anti-Syphon Trap

Resealing Bottle Trap

General

Resealing Bottle Traps are an alternative to Anti-Syphon Traps (Silentraps) and may be used in similar circumstances

Operation

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

Advantages

• The simple non-mechanical action ensures retention of adequate water seal even under extreme syphonic conditions
• Eliminates the need for secondary ventilation

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.
