The McAlpine C10V 75mm Water Seal Anti-Syphon (Silentrap) Bottle Trap with Multifit Outlet is a plumbing component used to prevent the backflow of sewer gases into a building's drainage system. It is designed to be used in conjunction with a basin, sink or bath waste outlet and features a 75mm water seal to prevent foul odours and bacteria from escaping into the air.
