## Long description

McAlpine HCN3100CB-15MM bath waste and overflow siphon is designed for combined waste and overflow connections in standard bathtubs. The assembly integrates a mechanical fill mechanism and an automatic brass fitting with a chrome finish, providing a unified solution for drainage, overflow protection and controlled filling. The product fits conventional 40/50 mm outlet plumbing and is intended for residential and light commercial installations where reliable water evacuation and safe overflow management are required.
Advantages
The combined design reduces the number of separate components needed for bathtub drainage and overflow, simplifying installation and maintenance. A mechanical fill system enables controlled water supply into the bath while the automatic brass component with chrome finish offers improved corrosion resistance and a durable visible surface. Compatibility with 40/50 mm outlets ensures straightforward connection to common waste pipes.
Suitable for
Standard domestic bathtubs in single-family homes and apartments
Light commercial installations such as guest rooms and short-stay accommodations
Replacement of existing combined waste and overflow assemblies
Plumbing projects requiring a mechanical fill and automatic overflow control
Key specifications
Type: combined bath waste and overflow siphon
Outlet diameter compatibility: 40/50 mm
Fill mechanism: mechanical fill
Overflow control: automatic operation integrated in brass component
Finish: chrome-plated brass visible fittings
Application: bathtub drainage and overflow management
How to use
Install the siphon according to local plumbing codes and the bathtub manufacturer’s instructions. Connect the 40/50 mm outlet to the waste pipe, secure the overflow connection to the bathtub overflow aperture and mount the chrome-plated brass fitting in the visible overflow/waste opening. Ensure proper seals and tight connections to prevent leaks. The mechanical fill is operated via the bath’s control mechanism; the automatic overflow function engages when water reaches the overflow level to prevent overfilling.
Usage recommendations
Before installation, verify outlet pipe dimensions and clearance under the bathtub. Use appropriate sealants or gaskets supplied or recommended by the bathtub manufacturer. Periodically inspect visible fittings and joints for signs of corrosion or leakage and clean aeration passages if necessary to maintain reliable automatic overflow and filling performance.
