The McAlpine TWLFCV is a screened breather, filter, and frost cover designed to prevent debris, insects, and frost from entering the waste system through the open end of a pipe. It features a compression joint that allows it to be easily connected to a waste pipe. The TWLFCV is designed to fit onto the open end of a waste pipe and prevent debris, insects, and frost from entering the system. The screened breather allows air to flow freely into the system, preventing the buildup of pressure that can cause damage to the pipes. The filter prevents larger debris from entering the system, reducing the risk of blockages and other issues. The frost cover helps to protect the system from damage caused by freezing temperatures, by preventing water from entering the system and expanding when it freezes. This helps to prevent pipes from bursting and other damage that can occur during freezing conditions. The compression joint on the TWLFCV makes it easy to install and remove, allowing for quick and easy maintenance of the waste system. The joint ensures a secure and leak-free connection to the waste pipe, helping to prevent leaks and other issues that can occur with poorly connected components. Overall, the McAlpine TWLFCV is a reliable and effective solution for preventing debris, insects, and frost from entering a waste system. Its screened breather and filter help to maintain airflow and prevent blockages, while its frost cover helps to protect the system from damage caused by freezing temperatures. The compression joint makes installation and maintenance quick and easy, ensuring a secure and leak-free connection to the waste pipe. Available in 1.25" and 1.5" sizes
It is designed and manufactured by McAlpine, a UK-based company that specializes in plumbing products.
