Product Overview
The Cherne 270024 2 in. Black Test Ball Plug is a reliable, inflatable rubber plug designed for testing DWV (Drain, Waste, and Vent) systems. Made from natural rubber, it provides excellent expansion and memory to seal both round and out-of-round pipes. Its compact design allows it to fit through test tees, sanitary tees, and floor drains, making it ideal for hard-to-reach areas. The plug utilizes a standard tire air fitting for easy inflation and includes a zinc-plated steel chain and ring to prevent it from being drawn into the system during testing. With a weight of 3.5 ounces and dimensions of 5.2″W x 4.8″H, it’s lightweight and durable for professional use.
Usage
This plug is used by plumbers, contractors, and maintenance professionals to test DWV systems for leaks and proper pressure. It’s especially useful in residential and commercial plumbing projects where tight spaces or irregular pipe diameters make traditional testing difficult. The plug can be inserted through test tees or floor drains and inflated to create a secure seal. It’s suitable for testing systems at pressures up to 13 PSI (equivalent to 30 feet of water). The plug’s design allows for quick installation and removal, reducing downtime during plumbing inspections.
