Bath waste trap McAlpine STY536AK chrome-plated automatic bath syphon (S)

The McAlpine STY536AK chrome-plated automatic bath syphon (S) is a bath waste trap designed for reliable drainage of standard bathtubs. It includes an automatic pop-up mechanism that allows the user to open and close the drain without reaching into the water. The chrome-plated finish provides corrosion resistance and a polished look that integrates with modern bathroom fittings. The unit is intended for domestic and light commercial bathroom installations where a compact automatic bath waste solution is required.

Advantages

The automatic pop-up action offers hands-free operation and improves hygiene by avoiding direct contact with water and debris. Chrome plating increases resistance to corrosion and simplifies maintenance, while the compact design fits most standard bath outlets and concealment spaces. Standard connection dimensions enable straightforward installation with commonly used bath piping, and the mechanism is engineered to provide smooth, reliable operation over repeated use.

• Domestic bathtub drainage in homes and apartments
• Light commercial bathrooms such as guest houses, small offices, or rental properties
• Replacement of existing bath waste traps with pop-up functionality
• Renovation projects requiring a chrome-finished drain solution

How to use

Install the bath waste trap according to the bath manufacturer’s instructions and local plumbing codes, ensuring secure connections to the waste pipe and proper sealing to prevent leaks.

Periodically inspect the chrome surface and mechanism for debris or mineral buildup and clean as needed to maintain smooth operation.

Usage recommendations

Use mild, non-abrasive cleaners for the chrome finish and avoid harsh chemical agents that can damage plating. Regularly check seals and connections for signs of wear and replace worn washers or gaskets to maintain leak-free performance. For installations in hard-water areas, consider periodic descaling to prevent reduced drainage efficiency.
