The OATEY tp424n is a commercial-grade True Set cleanout fitting designed for use in drain, waste, and vent (DWV) piping systems. It features a 4-inch connection size and a 6-inch nickel bronze top with ring, providing a durable and corrosion-resistant access point for drain line maintenance and inspection. Licensed plumbers install this cleanout in commercial plumbing systems where code-compliant access to underground or concealed drainage piping is required. The nickel bronze top delivers the finish durability and load-bearing characteristics expected in commercial environments.
The tp424n is suited for commercial construction and renovation projects where a finished, adjustable cleanout access point is required at grade or floor level. The True Set design allows the top to be set to finished floor height during installation, accommodating tile, concrete, and other finish materials. It is typically installed by licensed commercial plumbers working in accordance with applicable plumbing codes.
Designed as an OEM-style commercial cleanout for use with 4-inch DWV piping systems in commercial plumbing applications.
Installation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) or local authority having jurisdiction. Shut off water supply and ensure the drain line is not under pressure or active flow before installing or servicing the cleanout. Verify finished floor height before setting the top to ensure proper elevation alignment. Do not overtighten the top ring or plug, as nickel bronze components can be damaged by excessive torque.
