The Floplast White Anti-Vacuum Bottle Trap 76 mm Seal × 32 mm (TB37A) is a high-performance waste trap designed for bathroom and utility basins. It combines a deep water seal with an anti-vacuum feature to prevent unpleasant odours and maintain a reliable barrier in challenging drainage conditions.

Function & Purpose

This bottle trap connects under a sink or basin and creates a 76 mm water seal, which acts as a barrier against sewer gases entering the room. The anti-vacuum (anti-siphon) design prevents the water seal from being siphoned out when nearby fixtures drain quickly or when negative pressure occurs in the drainage system. This helps maintain the water seal and odour protection even during sudden changes in flow.

Compatibility

The TB37A is designed for 32 mm waste pipe connections, which are standard for most bathroom and utility basins. It fits with typical waste outlets and works alongside other compatible 32 mm drainage pipework.

Design & Build Quality

Finished in white for a clean, unobtrusive look beneath a basin, the trap is made from durable plastic materials built to withstand normal domestic use. The bottle configuration allows easy access for cleaning out trapped debris, and the anti-vacuum feature enhances long-term performance in busy drainage systems.

Ideal Applications

This anti-vacuum bottle trap is ideal for bathroom basins, utility sinks, or other fixtures where reliable odour protection is important and where rapid drainage might otherwise risk siphoning the water seal. It’s suitable for new installations, renovations, and trap replacements in residential and light commercial settings.
