## Long description

The McAlpine STW70LNL is a specialized 40mm extension piece engineered to facilitate the installation of HC26-CP and HC26-SS series shower tray siphons. This component is essential when working with shower trays that feature thicker walls, ensuring that the siphon assembly reaches the necessary depth for a secure and functional drainage system. By providing the required extra length, it allows for a professional-grade installation that maintains the integrity of the plumbing connection.
Advantages
This extension piece offers a robust solution for plumbing challenges encountered during shower tray assembly. Its design ensures a precise fit with compatible McAlpine siphon models, promoting a watertight seal that prevents leaks. The durable construction provides long-term reliability, making it a preferred choice for installers who require consistent performance and ease of integration into existing drainage setups.
Suitable for
Installation of HC26-CP series shower tray siphons in thick-walled trays
Installation of HC26-SS series shower tray siphons in thick-walled trays
Extending drainage connections where standard siphon depth is insufficient
When it may not be suitable
This product is specifically designed for use with the McAlpine HC26 series siphons and may not be compatible with other brands or different siphon models. It is not intended for use in applications where the shower tray wall thickness is standard or thin, as it may cause the siphon to protrude or fail to seal correctly.
Key specifications
Extension length: 40mm
Compatibility: McAlpine HC26-CP and HC26-SS series siphons
Material: High-quality plumbing-grade plastic
Application: Shower tray drainage systems
How to use
To install the extension, first ensure that the shower tray is properly positioned and that the drain hole is clear. Attach the extension piece to the siphon body according to the manufacturer's instructions for the specific HC26 model being used. Ensure that all seals and washers are correctly seated to prevent leakage. Once the extension is securely attached, proceed with the standard installation of the siphon into the shower tray waste outlet, tightening the connections firmly to ensure a watertight fit.
What to consider before purchase
Verify the model number of your existing McAlpine siphon
Measure the thickness of your shower tray wall to confirm the 40mm extension is required
Ensure compatibility with your specific drainage pipe diameter
Usage recommendations: Always check for leaks after installation by running water through the shower tray before finalizing the enclosure assembly. Ensure that all threaded connections are hand-tightened or tightened with appropriate tools to avoid damaging the plastic components.
