Ipex 149029 Cell Core Dwv Pipe 4 Inch 20 Foot

Product Description

The IPEX 149029 is a Cell Core DWV (Drain, Waste, and Vent) pipe designed for residential and commercial drainage systems. Cell core construction uses a foamed inner layer sandwiched between solid outer walls, reducing material weight while maintaining structural rigidity for gravity-flow drain lines. At 4 inches nominal diameter and 20 feet in length, this pipe is suited for main drain runs, horizontal branch lines, and vertical stacks in new construction and renovation work. Licensed plumbers and pipefitters are the primary installers for this product type.

This pipe is used in drain, waste, and vent systems where a 4-inch nominal pipe size is required. The 20-foot length makes it practical for long horizontal runs in residential slab or above-slab installations, as well as commercial rough-in work. It is appropriate for gravity-flow DWV applications where the pipe is not subject to continuous pressure service.

Key Features

• Cell core construction reduces overall pipe weight compared to solid-wall PVC pipe of the same diameter
• 4-inch nominal diameter accommodates standard DWV fittings and transitions
• 20-foot length minimizes the number of joints needed on long runs
• Designed for gravity-flow drain, waste, and vent applications

Compatibility

Designed as an OEM-style replacement and new-installation pipe for 4-inch nominal DWV systems using standard solvent-weld fittings and couplings.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local codes. Solvent-cement joints require proper priming and cementing procedures specific to PVC DWV pipe. Support spacing and slope requirements for 4-inch horizontal drain lines should follow code-specified minimums. Always verify local code acceptance of cell core pipe for the intended application before installation.
