Details

Poorly ventilated waste systems often create a vacuum during discharge. This process pulls water out of your traps and allows unpleasant sewer gases to enter your living space. Finding a space-saving solution that fits existing 40mm or 43mm waste pipes without requiring major plumbing alterations is often difficult.

The McAlpine VP2W solves these problems by providing a simple, compression-fit valve that stops vacuum siphoning immediately. Because the unit fits standard 1.5″ pipes and includes a multifit socket, you can install it quickly without specialized tools. It keeps your indoor environment fresh and ensures your drains flow freely.
