The McAlpine C10AV is a bottle trap designed for use with washbasins or sinks. It features a 75mm water seal and an adjustable inlet that allows it to be easily fitted to a variety of waste pipe sizes. The trap also includes a multifit outlet, making it compatible with a wide range of plumbing systems. What sets the McAlpine C10AV apart is its anti-siphon or "silentrap" function. This means that the trap is designed to prevent the loss of the water seal and the ingress of foul air, even in the event of negative pressure or vacuum in the drainage system. This is particularly important in buildings with high-rise plumbing systems, as negative pressure can cause water to be sucked out of the trap, breaking the water seal and allowing unpleasant odours and gases to enter the building. The anti-siphon function of the McAlpine C10AV ensures that the water seal remains intact, preventing the ingress of foul air and maintaining the integrity of the plumbing system. The McAlpine C10AV is a high-quality bottle trap that is easy to install and offers reliable performance. Its adjustable inlet and multifit outlet make it a versatile choice for a range of plumbing applications. The anti-siphon function ensures that the trap continues to function correctly, even in buildings with high-rise plumbing systems, making it an ideal choice for commercial or residential properties where maintaining the integrity of the plumbing system is critical.
