This cap allows plumbers to simultaneously test two pipe sizes from a single fitting, reducing the number of tools needed on the job. The dual-size design fits both 3-inch and 4-inch pipe openings, making it a practical choice for rough-in inspections and system verification before walls are closed. Licensed plumbers and pipefitters typically use test caps during DWV rough-in stages to confirm system integrity under required test pressures per applicable plumbing codes.\u003c\/p\u003e\u003cp\u003eThis test cap is suited for residential and light commercial plumbing applications where DWV systems require pressure or air testing prior to inspection sign-off. It is commonly used during new construction and remodel work where the plumbing rough-in must pass inspection before proceeding to finish work. The dual 3-inch and 4-inch sizing covers the most common drain and waste pipe diameters found in residential plumbing installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual-size design fits both 3-inch and 4-inch pipe openings\u003c\/li\u003e\n\u003cli\u003eIntended for pressure and air testing of DWV piping systems\u003c\/li\u003e\n\u003cli\u003eReduces required test equipment by combining two sizes into one cap\u003c\/li\u003e\n\u003cli\u003eDesigned for use during rough-in inspection stages\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-use test cap for 3-inch and 4-inch DWV piping systems in residential and light commercial plumbing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC).
