The McAlpine ASA10V is a 75mm water seal adjustable inlet tubular swivel anti-syphon (Silentrap) 'P' trap with a universal outlet. This type of trap is commonly used in plumbing applications to prevent sewer gases from entering a building through the drainage system. The anti-siphon (Silentrap) feature of the McAlpine ASA10V prevents the trap from being siphoned dry, which can lead to loss of the water seal and the entry of sewer gases into the building. The anti-siphon feature creates a vacuum break that prevents the trap from becoming siphoned dry, ensuring that the water seal remains intact and the building is protected from unpleasant odors and potential health hazards. The adjustable inlet allows for easy installation and alignment of the trap with the waste pipe, while the swivel 'P' shape of the trap allows for flexibility in the connection to the waste pipe, making it easier to install in tight spaces. The universal outlet of the trap allows for connection to a variety of waste pipes with different diameters and materials, making it a versatile option for many plumbing applications. Overall, the McAlpine ASA10V is a reliable and safe choice for plumbing applications that require a water seal adjustable inlet tubular swivel anti-syphon 'P' trap with a universal outlet. It is particularly suitable for applications where there is a risk of the trap being siphoned dry, such as in bathrooms or kitchens with low water flow rates or high drainage rates. ・ Available in 1¼", 1½", and 2" sizes ・ 75mm Water Seal ・ Universal Compression Outlet suits all plastic, copper and lead pipe ・ Adjustable Inlet makes trap suitable for all domestic repair, maintenance and improvement work ・ Anti-Syphon Valve neutralises negative syphonic pressure and eliminates gurgling
