## Summary description

Vertical extension for washbasin trap McAlpine RS4, length 300 mm, connection size 5/4" with integral flange. Designed to extend the vertical run of a basin trap where extra drop is required or to reach a concealed outlet. Made for compatibility with standard 5/4" washbasin siphons; used in bathroom installations to adjust height and improve alignment with waste pipework.

## Long description

McAlpine vertical extension for washbasin trap RS4, length 300 mm, connection size 5/4" with integral flange is a plumbing component designed to increase the vertical run of a basin trap. It provides an additional drop between the washbasin outlet and the trap connection, allowing installers to align the trap with concealed soil stacks or recessed waste outlets. The product is compatible with standard 5/4" washbasin siphons and includes a flange to create a neat seal against the basin or wall surface.
Advantages
The vertical extension is made to simplify height adjustments in bathroom waste installations and to provide a secure, leak-resistant connection when more drop is required. Its integral flange helps distribute compression evenly and aids in a tidy finish at the junction point. The 300 mm length offers a substantial extension without requiring bespoke pipe cutting, and the standard 5/4" connection ensures interoperability with common washbasin traps and fittings.
Suitable for
Extending the vertical drop between a washbasin outlet and a trap
Connecting traps to concealed or recessed waste outlets
Adjusting trap height for alignment with existing soil stacks
Bathroom installations where additional clearance or reach is required
Key specifications
Length: 300 mm
Connection size: 5/4" (standard washbasin siphon connection)
Integral flange for sealing and neat finish
Intended use: vertical extension for washbasin trap
How to use
Install the vertical extension by removing the existing trap connection and inserting the extension between the washbasin outlet and the trap. Ensure the 5/4" connections are fully engaged and that the integral flange sits flush against the basin or wall surface. Tighten fittings to the manufacturer-recommended torque for a secure, leak-free joint and verify alignment with the soil stack or waste outlet before final tightening. After installation, run water to check for leaks and adjust seals as necessary.
Usage recommendations
Use with standard 5/4" washbasin traps and compatible seals; avoid forcing mismatched fittings. Where access is restricted or piping changes are complex, confirm alignment and clearance prior to final installation to ensure a reliable, watertight connection.
