Fernco fernco-dtc-215 Drain Test Cap

Product Description

The FERNCO fernco-dtc-215 is a drain test cap used to pressure-test and isolate drain, waste, and vent (DWV) piping systems during rough-in inspection. Test caps allow plumbers and pipefitters to plug a pipe opening, pressurize the line, and verify system integrity before walls are closed or fixtures are set. The fernco-dtc-215 is a temporary mechanical fitting designed for use during the inspection phase of residential and light commercial plumbing work, making it a standard tool on any rough plumbing job site.

This drain test cap is suited for use on DWV piping systems in residential and light commercial construction. It is typically installed by licensed plumbers during the rough-in stage, prior to plumbing inspection, to allow the system to hold air or water pressure for the required test duration. The cap is removed after the inspection is complete and final connections are made.

Key Features

• Designed for temporary use during DWV pressure and leak testing
• Mechanical design allows installation and removal without special tools
• Suitable for residential and light commercial plumbing applications
• Supports standard air and water pressure testing procedures

Compatibility

Designed as an OEM-style replacement-style drain test cap for use on standard DWV piping systems during rough-in plumbing inspection.

Installation Notes

Installation is performed by a licensed plumber during the rough-in phase of construction, prior to system inspection. Verify that all downstream connections are capped or sealed before pressurizing the system. Follow local plumbing code requirements, including IPC guidelines, for the correct test pressure and duration. Remove the test cap after inspection is complete and before permanent fixtures are installed.
