The Charlotte Pipe Foundry PVC 00117 0800HA is a Schedule 40 PVC sewer pipe adapter coupling designed to connect 3-inch DWV IPS pipe to 4-inch sewer pipe in drainage, waste, and vent systems. Configured as a hub x hub fitting, it accepts pipe on both ends for a solvent-welded joint. This 400 Series coupling is used by licensed plumbers to transition between Schedule 40 IPS DWV piping and larger 4-inch sewer lines, a common requirement in residential and light commercial drain system rough-in work. The fitting ships in a package quantity of 20 units, making it suitable for stocking on job sites or in supply houses.
This adapter coupling is used in underground and above-grade DWV piping systems where a branch or main line steps up from 3-inch Schedule 40 IPS pipe to a 4-inch sewer main. Typical applications include residential drain rough-ins, building sewer laterals, and commercial plumbing systems where IPS-sized DWV runs terminate into larger sewer headers. The 400 Series designation indicates compliance with standard sewer pipe dimensional profiles for this transition fitting.
Designed to adapt 3-inch Schedule 40 IPS DWV pipe to 4-inch sewer pipe (400 Series) in standard PVC drainage, waste, and vent systems.
Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water supply and ensure the drain system is depressurized and clear before cutting into existing lines. Solvent-cement both hub ends using PVC primer and an approved Schedule 40 PVC cement following the manufacturer and code guidelines for cure time before restoring flow. Inspect joints for full solvent weld coverage before backfilling or concealing the line.
