The cap seals the open end of a 3-inch pipe, allowing the system to hold pressure during inspection. A knockout center lets the installer pop out the plug once testing is complete, restoring flow without removing the fitting. Licensed plumbers use this cap during rough-in inspections to satisfy local plumbing code test requirements.\u003c\/p\u003e\n\u003cp\u003eThis test cap is sized for 3-inch plastic pipe and is suited for residential and light commercial DWV applications. It is commonly used during new construction and remodel rough-ins where the authority having jurisdiction requires a witnessed pressure or air test of the waste and vent system before walls are closed. The knockout design saves time by eliminating the need to cut out a temporary cap after the test passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch pipe size fits standard plastic DWV pipe and fittings\u003c\/li\u003e\n  \u003cli\u003eKnockout center allows single-tool removal after test completion\u003c\/li\u003e\n  \u003cli\u003ePlastic construction is lightweight and compatible with PVC and ABS drain systems\u003c\/li\u003e\n  \u003cli\u003eDesigned for pressure and air testing of DWV piping per plumbing code requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style test cap for 3-inch plastic DWV piping systems.
