## Summary description

McAlpine MP31SSF-WHBR is an automatic bathtub siphon designed for concealed waste drainage in bathtubs. Finished in white with a brass knob, it provides automatic opening and closing of the waste outlet for easy water release and sealing. Suitable for standard bathtub installations where a built-in automatic waste control is required.

## Long description

The McAlpine MP31SSF-WHBR automatic bathtub siphon is a concealed waste control device for bathtubs, featuring a white body and a brass finish knob. It provides an automatic opening and closing function for the waste outlet, allowing controlled water release and reliable sealing when closed. Designed for standard bathtub installations, the siphon integrates with hidden drainage systems to maintain a clean visible surface and simplify bath use.
Advantages
The siphon offers automatic pop-up waste operation that can be controlled via the brass knob on the visible surface, combining aesthetic appearance with practical functionality. Its concealed design reduces exposed components around the bath rim, and the white body matches common bathtub interiors. The mechanism is intended to give a watertight seal when closed and straightforward water drainage when opened.
Suitable for
Standard built-in bathtubs with concealed waste piping
Renovations where a neat, low-profile waste control is desired
Bathrooms requiring a white-finished waste with a brass control knob for matching fittings
When it may not be suitable
This automatic siphon is intended for standard bathtub drain configurations; it may not fit non-standard or custom waste systems without compatible inlet/outlet dimensions. It may also be unsuitable where an exposed or external overflow system is specified or where specific non-standard materials or finishes are required.
Key specifications
Function: automatic opening and closing pop-up waste
Body finish: white
Control knob finish: brass
Installation type: concealed bathtub waste
Operation: manual knob actuation for release and seal
How to use
Install the siphon in the bathtub drain according to manufacturer guidance and ensure the concealed waste piping aligns with the unit. Operate the waste by turning or pressing the brass knob as intended to switch between sealed and open states; verify the seal by filling the tub partially and checking for leaks. Routine operation involves normal manual actuation of the control knob to retain or release bath water.
What to consider before purchase
Confirm compatibility with your bathtub's waste connection and concealed piping layout
Ensure the white body and brass knob match other bathroom fittings
Check required installation clearances and access for maintenance
Usage recommendations
For reliable performance, inspect the sealing surfaces during installation, tighten fittings to appropriate torque without over-tightening, and test the pop-up operation before finalising the bath trim. If uncertain about fit or plumbing connections, consult a qualified plumber to ensure correct installation and leak-free operation.
