Why this adapter stands out
When you’re working with mixed-sized ABS piping in an above-ground DWV run, the need for a clean, secure transition is real. This adapter gives you a straightforward 3" spigot to 4" hub solution, eliminating the guesswork of attempting incompatible fittings. The ABS material is specifically chosen for gravity-fed drainage systems, offering solid chemical compatibility and a durable bond with standard ABS cement.
Ideal use cases
- Converting a 3" spigot drain line to mate with a 4" hub waste line in a bathroom or utility room
- Replacing aged connections where a 3" pipe must tie into a larger 4" hub segment
- Above-ground DWV installations where underground rating isn’t required
Practical installation tips
- Dry-fit the joint first to confirm alignment between the 3" spigot and 4" hub sections.
- Clean both mating surfaces and apply a suitable ABS solvent cement designed for DWV systems.
- Carry out a full cement cure time per the cement manufacturer’s instructions before testing for leaks.
- Ensure the surrounding piping remains free of stress or movement after installation to maintain a watertight seal.
Whether you’re tackling a residential remodel, a fixture replacement, or a simple DWV upgrade, this Charlotte Pipe adapter delivers a dependable, size-matched connection that keeps your drainage flowing smoothly. Choose it when you need a proven 3" spigot to 4" hub transition that integrates cleanly with existing ABS piping and standard cemented joints.
