Description
What is a Solvent Weld Equal Tee used for?
A solvent weld equal tee (often referred to as a sanitary tee or T-junction) is a specialized fitting used to merge two separate 40mm waste lines into a single discharge pipe. It is most commonly used in kitchen and utility room installations where a sink and an appliance (like a dishwasher) share the same exit route to the external soil stack. The “equal” designation confirms that all three openings are a standard 40mm diameter.
Why Choose Solvent Weld over Push-fit for Junctions?
At ECO HEAT SHOP, we recommend the black solvent weld tee for high-traffic drainage systems. Unlike push-fit junctions that rely on rubber seals—which can be compromised by grease buildup or thermal movement—a solvent-welded junction creates a permanent chemical bond. Once the solvent cement is applied, the fitting and the pipes fuse into a single solid unit, ensuring a 100% airtight and watertight seal that will never slip or perish.
Engineered for Resilience and Flow Efficiency
Our 40mm equal tees are manufactured from high-grade ABS (Acrylonitrile Butadiene Styrene). This material is the preferred choice for UK trade professionals because it is exceptionally rigid, impact-resistant, and capable of handling intermittent boiling water (up to 90°C) without sagging. The 92.5-degree angle is a critical technical feature, providing the mandatory 2.5-degree pitch required by UK building regulations to prevent stagnant water and foul odors.
