The McAlpine STW4-M is a 50mm water seal resealing shower trap with a multifit outlet. This trap is designed to be used in shower and wet room installations, where it helps to prevent the build-up of unpleasant odours by trapping water in the waste pipe and preventing sewer gases from entering the room. One of the key features of the McAlpine STW4-M shower trap is its resealing mechanism. This trap is designed to allow water to flow through it freely, but if there is no flow for an extended period, the trap will automatically reseal itself to prevent any sewer gases from entering the room. Another important feature of the McAlpine STW4-M is its multifit outlet. This allows the trap to be connected to a range of waste pipe sizes and types, making it a versatile option for a wide range of plumbing installations. The McAlpine STW4-M shower trap is also easy to install, thanks to its simple design and the fact that it can be easily removed for cleaning and maintenance. Its compact size makes it well-suited to installations where space is limited, while its durable construction ensures that it will provide reliable and long-lasting performance.

Its resealing mechanism, multifit outlet, and easy installation make it a popular choice for both domestic and commercial plumbing installations.
