3 inch Poly Test Cap Insert

1836006 Wal-Rich 3" Test Cap Insert – Pressure-Test Component for DWV Systems

The 1836006 3" test cap insert from Wal-Rich is designed for temporary sealing of drain, waste, and vent (DWV) piping systems during pressure or leak testing. This fitting enables inspection and verification of system integrity prior to final commissioning. It is suitable for use in new installations, rough-in phases, and repair work where temporary closure of open pipe ends is required.

Technical Specifications

• Manufacturer: Wal-Rich Corporation
• Model: 1836006
• Type: Test cap insert for DWV systems
• Nominal Size: 3 inches
• Material: High-density polymer (non-corrosive, chemical-resistant)
• Application: Temporary pressure testing and system isolation
• Compatibility: Fits inside standard 3" nominal DWV pipe (PVC, ABS, or cast iron, depending on manufacturer specs)

Installation Guidelines

Insert the test cap into the open pipe end to create a temporary seal. For pressure testing, ensure that the cap is fully seated and leak-free. If specified, use compatible thread sealant or mechanical fasteners depending on the pipe material and test pressure. Follow all applicable code requirements and manufacturer's testing protocols. Do not use in pressurized potable water or gas systems.

Application Use

Commonly used in:

• Residential and commercial DWV systems
• New construction or rough-in plumbing installations
• Renovation projects requiring section isolation
• Code-mandated system pressure testing and inspections

Performance Considerations

Test caps must be installed in accordance with local plumbing codes and should only be used for temporary system closure and testing purposes. Once inspections are complete, remove and replace with permanent fixtures or caps as required. Always verify pressure and material compatibility before use.
