McAlpine AA10 Resealing Bottle Trap | 75mm Seal | Self-Ventilating | 1¼" Outlet

Description

The McAlpine AA10 is a self-ventilating resealing bottle trap — designed for basin and sink installations where secondary ventilation isn't practical. When syphonic conditions occur, the automatic hydraulic action draws air through the bypass columns to break the syphon; once conditions normalise, remaining water falls back to reseal the trap. No mechanical parts, no secondary vent pipe required.

Key Features

  • 75mm water seal — superior odour protection; deeper than the standard 50mm seal
  • Self-ventilating / resealing design — eliminates the need for secondary ventilation; no moving parts to fail
  • Adjustable inlet — fits all standard domestic basin and sink wastes
  • 1¼" (32mm) multifit compression outlet — compatible with plastic, copper, and lead waste pipes
  • Polypropylene construction — durable, corrosion-resistant, and chemical-resistant
  • BS EN 274-1:2002 compliant — meets British and European performance standards

Frequently Asked Questions

What is a resealing bottle trap?

A resealing (or self-ventilating) trap is designed to prevent the water seal from being lost under syphonic conditions — where fast-flowing water in the waste pipe creates a vacuum that can suck the water out of a standard trap. The AA10 uses a hydraulic bypass mechanism to break the syphon and allow the trap to reseal automatically, without needing a separate anti-syphon valve or vent pipe.

Do I need secondary ventilation with this trap?

No — the self-ventilating design of the AA10 eliminates the need for secondary ventilation in most domestic installations. This makes it particularly useful in situations where running a vent pipe is impractical or impossible.

Can I order if the item shows as out of stock?

Yes — this product can be ordered even when showing as out of stock, and we'll fulfil your order as soon as stock is available. If you need a specific delivery timeframe, please contact us at customerservice@bubblegumbathrooms.co.uk before ordering.
