The Fluidmaster Pro Standard Bottle Trap – Anti-Vac 32/40 mm (PRO7055) is a high-quality sanitary waste trap designed for use with washbasins, hand basins, and similar fixtures. It combines a compact bottle trap design with an anti-vacuum (anti-siphon) feature to ensure effective drainage and prevent odour-causing gases from entering the room.

Function & Purpose

This bottle trap forms a water seal beneath the basin outlet that stops sewer gases and unpleasant odours from rising into the living space. The anti-vac feature prevents siphoning of the water seal during rapid drainage or system pressure changes, ensuring the trap retains its protective water barrier. The design accommodates both 32 mm and 40 mm waste connections, making it versatile and easy to fit with standard plumbing pipework.

Compatibility

The trap is suitable for basin and washbasin waste applications with 32 mm or 40 mm outlet pipes. Its adjustable connections allow it to interface with standard waste fittings, tailpieces, and installation scenarios commonly found in bathrooms and utility rooms.

Design & Build Quality

Constructed from durable, corrosion-resistant plastic, the Fluidmaster Pro bottle trap is engineered for long-lasting performance. The anti-vac valve helps maintain the water seal under varying drain flows, and the overall design allows easy access for cleaning and maintenance if debris accumulates.

Ideal Applications

This bottle trap is ideal for bathroom and utility basins where reliable odour control and efficient waste drainage are required. It’s particularly useful in installations where rapid water flow might otherwise risk siphoning the trap seal, such as in frequently used bathrooms or utility areas. The dual 32/40 mm compatibility makes it versatile for new installations or replacements in domestic and light commercial settings.
