1 in. DWV WYE Hub Skew Y-Tee PVC Fitting ASTM D2665 NSF

The 247Garden 1-Inch DWV (Drain, Waste, and Vent) Skew Y-Tee PVC Fitting is engineered to provide smooth, efficient directional changes in low-pressure, non-pressurized piping systems. Constructed from high-strength polyvinyl chloride (PVC) and meeting ASTM D2665 specifications, this fitting is NSF-certified for quality, reliability, and material safety.

The unique skewed wye design allows for an offset branch connection that promotes optimal fluid or air flow, minimizes turbulence, and simplifies installations in confined or misaligned piping layouts. It provides an effective transition between horizontal and vertical lines in both drainage and venting applications.

Typical Applications

Plumbing and Drainage Systems

The DWV Skew Y-Tee connects lateral drain lines to vertical stacks or main lines while maintaining smooth flow. It is ideal for waste line transitions under sinks, floor drains, or condensate systems. The angled design minimizes blockage risk by ensuring a gradual directional change.

Venting Systems

Used in vent stacks and air-admittance piping, this fitting helps equalize air pressure in DWV systems. Its skewed design allows flexibility in tight or offset spaces where standard Y-fittings cannot align properly.

Hydroponic and Aquaponic Systems

In hydroponic setups, the 1-inch DWV Skew Y-Tee effectively splits or combines nutrient solution return lines. It ensures smooth gravity-fed flow between growing trays, reservoirs, or drain manifolds. The corrosion-resistant PVC body makes it ideal for continuous exposure to nutrient-rich water and aeration systems.

Irrigation and Water Management

This fitting is useful for drainage return lines, overflow management, or vented loops in irrigation manifolds. It allows users to divert or merge flows efficiently without restricting gravity-fed drainage systems.

Laboratory and Industrial Systems

Suitable for vented drainage in laboratory sinks, process tanks, or chemical handling stations. Its PVC construction resists corrosion and chemical degradation, offering durability in both clean water and chemical waste applications.

Aquarium and Pond Plumbing

Used in sump return or overflow plumbing, the Skew Y-Tee supports smooth, low-turbulence water flow for filtration systems. It helps maintain consistent water circulation in aquariums, ponds, and aquatic recirculation systems.
