Cherne 238701 Inset Test Cap 1.5 in Dwv Schedule 40

Product Description

The CHERNE 238701 is a 1.5-inch inset test cap designed for pressure testing drain, waste, and vent (DWV) piping systems. The cap inserts into the pipe end and seals the line to allow air or water pressure testing during rough-in inspection. Rated to 10 psi, it is compatible with Schedule 40 pipe and connects via solvent weld. The body is molded from ABS plastic with a white finish. Plumbers and pipe inspectors use this fitting during new construction and remodel work to verify system integrity before closing walls or slabs.

This test cap is suited for residential and light commercial DWV applications where Schedule 40 PVC or ABS piping at 1.5 inches is installed. Typical use cases include capping branch lines, cleanout stubs, and vent stacks during pressure or flood tests required by local plumbing inspection authorities. The solvent weld end connection creates a reliable, temporary or permanent seal depending on installation intent.

Key Features

• Inset design seats inside the pipe end for a secure, leak-resistant seal during DWV pressure testing
• 10 psi pressure rating meets standard DWV test requirements
• Solvent weld end connection compatible with Schedule 40 pipe
• ABS plastic construction resists corrosion and chemical exposure common in drain systems
• Manufactured to ISO 9001 quality standards and recognized for LEED-compliant projects

Compatibility

Designed as an OEM-style test fitting for 1.5-inch Schedule 40 DWV piping systems using solvent weld connections.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Before testing, ensure all upstream water supply and drainage flow is shut off and the system is depressurized. Apply the appropriate solvent cement for ABS or PVC pipe per the cement manufacturer instructions and local plumbing code requirements, referencing the IPC or applicable jurisdiction standard. Do not exceed the 10 psi rated test pressure during air or hydrostatic testing.
