• Odour-Free Drainage: Designed with a built-in water trap and unique double-trapped system to block unpleasant drain odours.

• Roddable & Easy to Clean: Includes a fully removable dip-tube and internal trap mechanism, providing immediate access for easy drain rodding and debris clearance.

• Inlet Versatility: Features a socketed back inlet alongside a $90^\circ$ main outlet, perfect for combining domestic waste water (kitchens, utility rooms) and surface rainwater.

• Leak-Proof Connection: Manufactured with Brett Martin's market-leading captive seal, which ensures the seal stays securely in place during installation to prevent displacement or leaks.

• Heavy-Duty Construction: Made in the UK from high-strength, impact-resistant polymer—fully certified to BS EN 1401 standards for long-lasting underground durability.

The Brett Martin B1001 Back Inlet Roddable Bottle Gully is an essential, high-performance component for your gravity-fed underground drainage systems. Specifically engineered to manage domestic gray water from ground-floor kitchens, utility rooms, and bathrooms, this versatile gully also efficiently collects surface rainwater run-off from downpipes and paved spaces.

Maintenance Made Simple - Unlike standard underground gullies that require difficult excavation if a blockage occurs, the B1001 is fully roddable. By simply unscrewing the secure round plastic grid and lifting out the inner dip-tube, you gain direct, unobstructed access to the downstream $90^\circ$ outlet pipework to easily clear debris or run drain rods.

Engineered to Perform - Brett Martin's underground fittings are renowned for their installation speed and structural integrity. Equipped with an advanced captive seal jointing system, the rubber seals are physically locked in place. They will not roll, twist, or dislodge when pushing your 110mm PVC pipes home. The integrated double-trap water barrier ensures that raw sewer gases are permanently blocked from escaping into external pedestrian areas or back toward your property.
