4 inch PVC Sewer and Drain Cleanout Adapter Fitting x Female

4 inch PVC Sewer & Drain Cleanout Adapter – Solvent Weld Fitting for DWV Access Points

The 4 inch PVC Sewer and Drain Cleanout Adapter is a solvent-weld fitting designed for integration into non-pressurized DWV (Drain, Waste, and Vent) piping systems. This fitting provides access for cleaning and inspection of horizontal and vertical sewer lines and is manufactured to meet performance criteria for underground and above-grade installations.

Constructed from high-strength polyvinyl chloride (PVC), the adapter conforms to ASTM D3034 and CSA B182.2 standards, making it compatible with SDR 35 and Schedule 40 systems when properly transitioned. The female-threaded top accepts standard cleanout plugs, allowing for code-compliant access and maintenance without disrupting system function.

Technical Specifications

• Nominal Size: 4 inches
• Material: PVC (polyvinyl chloride), Type 1, Grade 1
• Connection: Spigot x Female Thread (FPT)
• Standards: ASTM D3034, CSA B182.2, applicable to SDR 35 PVC systems
• Usage: Gravity-flow sewer and drainage applications

Installation Requirements

Clean and dry both mating surfaces. Use an appropriate primer and solvent cement approved for PVC connections per ASTM D2855. For threaded terminations, apply a non-hardening, compatible thread sealant. Install with the access port positioned for future maintenance accessibility, in compliance with local code setback and clearance regulations.

Typical Applications

This cleanout adapter is commonly installed in building drain lines, lateral sewer branches, and manhole risers. It provides accessible points for inspection, mechanical snaking, or hydro-jetting, and is used in both new construction and retrofit conditions.

Material Characteristics

PVC offers resistance to biological and chemical degradation, UV stability in protected environments, and ease of installation with solvent-weld technology. The threaded outlet accommodates PVC or brass cleanout plugs, allowing for reliable reseal after service access.
