3 inch x 3 inch x 1-1/2 inch PVC DWV 90 Degree Low Heel Elbow Plastic x Plastic

3 inch x 1-1/2 inch PVC DWV L-Heel 90° Elbow – Transition Fitting for Horizontal to Vertical Drainage

The 3 inch x 1-1/2 inch PVC DWV L-Heel 90° Elbow is engineered to facilitate directional changes in drain, waste, and vent (DWV) piping systems. This reducing elbow provides a 90-degree turn with a center-side inlet or outlet, allowing efficient redirection of low-pressure wastewater flow where size transition and directional offset are required.

Manufactured from rigid polyvinyl chloride (PVC), the fitting delivers chemical resistance and dimensional stability under typical DWV operating conditions. It is designed for solvent-weld connections and is compatible with Schedule 40 DWV pipe configurations in accordance with industry standards.

Key Performance Characteristics

• ✅ DWV-Specific Design – Intended for use in non-pressurized drain and vent systems operating under gravity flow.
• ✅ Reducing Configuration – Allows transition between 3 inch and 1-1/2 inch pipe sizes within lateral or branch lines.
• ✅ Formed for Clean Flow Paths – Smooth interior surface and accurate sweep reduce turbulence and sediment accumulation.
• ✅ Solvent Weld Socket Connections – Offers secure jointing when used with approved primer and cement, minimizing the risk of joint failure.
• ✅ Corrosion and Chemical Resistance – Inert PVC formulation is suitable for residential and commercial sanitary drainage environments.

Technical Specifications

• Material: Schedule 40 PVC (Polyvinyl Chloride)
• Nominal Sizes: 3 inch x 1-1/2 inch
• Connection Type: Hub (Socket) x Hub
• Angle: 90 Degrees
• System Rating: Gravity-fed DWV; not intended for pressurized service
• Compliance: Meets ASTM D2665, CSA B181.2, and applicable plumbing code requirements

Installation Requirements

Install using solvent cement and primer in accordance with manufacturer recommendations and local code. Proper pipe deburring, surface preparation, and joint alignment are essential for leak-free performance. This fitting is designed for above-ground or underground use in systems that do not experience internal pressure.

Typical Applications

Commonly used in sanitary drainage layouts to redirect horizontal flow downward while adapting to a reduced pipe diameter. Applications include residential waste stack offsets, vent system transitions, and fixture drain branches. Often found in basements, crawl spaces, and slab systems where vertical clearance is limited.

Material Insight

PVC Schedule 40 DWV fittings are preferred in non-metallic drainage systems for their lightweight composition, corrosion resistance, and ease of fabrication. The L-heel configuration enhances layout flexibility by allowing horizontal-to-vertical redirection in limited-space environments.

The 3 inch x 1-1/2 inch PVC L-Heel 90° Elbow offers a code-compliant, corrosion-resistant solution for size-reducing directional transitions in DWV systems. Designed for long-term reliability in both new construction and retrofit plumbing layouts.
