The Davant 110mm Solvent Weld Soil 92° Double Socket Branch Tee with Boss is a reliable and versatile fitting designed to join three sections of soil pipe while also accommodating an additional connection point via the integrated boss. Designed for use with standard 110mm (4") solvent weld soil systems, this fitting is ideal when you're expanding a soil stack or introducing a branch to an existing run.
Its 92-degree branch provides a slightly more open angle than a strict 90°, promoting smoother waste flow and reducing the chance of blockages. This small design feature makes a big difference in performance, especially in systems with frequent use or complex layouts.
The double socket configuration allows you to connect two 110mm pipes directly into the fitting using solvent weld joints, while the third socket connects the branch section. The integrated boss is perfect for connecting smaller diameter waste pipes—such as 32mm or 40mm from sinks, showers, or washing machines—using a compatible boss adaptor.
Crafted from high-quality PVC-U, the fitting is strong, durable, and corrosion-resistant. Suitable for both indoor and outdoor applications, it stands up to environmental stress and long-term use. It’s available in black or olive grey to suit different system aesthetics and is fully compliant with EN1329-1 and EN1566-1 standards.
Frequently Asked Questions
What is the integrated boss used for?
The boss allows you to connect a smaller waste pipe—like one from a basin or washing machine—into the main soil system. It adds flexibility without needing an entirely separate fitting.
Why is a 92° angle better than a standard 90° branch?
The extra 2° creates a gentler path for waste to flow, helping reduce the likelihood of build-ups and ensuring a more efficient system, particularly in gravity-fed drainage setups.
Can this fitting be used in outdoor soil stacks?
Yes, absolutely. The tough PVC-U material is weather-resistant and durable enough for external use. Plus, it’s available in black or olive grey to help match your system's look.
