The Cherne Test-Ball has been the contractor's choice for over 50 years and continues to be the most trusted pneumatic test ball in the industry. Designed for applications from pressure testing and blocking of residential DWV systems to repair maintenance and installation of municipal infrastructure including storm and sanitary sewer piping systems, the Cherne Test-Ball does it all.
Cherne Test-Balls are durable, rugged and effective in any type of pipe.
The Muni-Ball® Plug was introduced over 50 years ago and the Cherne brand continues to be the most trusted name in pneumatic plugs.
The Muni-Ball® Plug offers a full bypass allowing both testing and monitoring of the piping system. The Cherne Muni-Ball® is ideal for installation and repair of residential or commercial piping applications. Cherne Muni-Ball® products can be used for maintenance of municipal infrastructure, including sanitary and storm sewer pipe systems. Muni-Ball® plugs are durable, rugged and are effective on almost any type of pipe.
Cherne's Gripper plugs can be used in a variety of applications including DWV (drain, waste and vent) testing and stack testing. End-of-Pipe design won't fall in, whereas the Inside-of-Pipe design allows you to locate the plug inside the pipe as far as you need. Time tested, the Gripper® remains one of the most popular mechanical plugs on the market.
Big-Mouth® plugs serve multiple applications. Great for gravity bypassing or bypass pumping.
Custom sizes for 5"-18" also available; call for more info
Fast, safe and easy to use, a five-second test determines joint integrity. Cherne's Air-Loc® Joint Tester is designed to test large-diameter, installed, pre-cast concrete pipe as described in ASTM C1103.
Ready to test with water or air straight from Cherne's factory—no modifications are needed—the Air-Loc® Joint Tester also allows you to pre-test before backfilling. Capable of testing to 15 PSI air or 50 psi water.
Air-Loc® Manhole Testers provide the most efficient, accurate and cost-effective method of testing new, existing and rehabilitated manholes, per ASTM C 1244. Vacuum testing identifies infiltration and exfiltration problems by creating a vacuum in a manhole and then monitoring a gauge for vacuum loss. Less expensive and faster than water testing, the Air-Loc® manhole tester's remote-inflation and monitoring system keeps users away from the "danger zone".

Cherne's Pillow-Style Muni-Ball® plugs are great for blocking sewer flow and can also be used for sewer air testing. Made from heavy-duty elastic urethane, these plugs are lightweight, flexible, chemical and petroleum-resistant, and will fit through small-diameter openings. Pillow-style plugs can be tethered with the attached tether bars, and will work in all types of pipe, including ductile iron sizes.

Hydrostatic Test Pumps are designed for pressure testing water lines and sewer force mains as prescribed by AWWA Standard C600 Installation of Ductile-Iron Water Mains and C605 Installation of PVC Pressure Pipe.
Aqua-Loc® Hydrostatic Test Pumps are designed to be the most user friendly in the industry.
Available for line acceptance and/or leak location tests
Air-Loc® leak locator plugs are designed for both low-pressure sewer line acceptance tests as well as leak location testing. Air-Loc® plugs can also be used to block flow by simply plugging the fill and read-back ports.
The 3/8" diameter hose assembly is used to connect the Air-Loc Panel to the front plug. Triple hose is color-coded, making connections easy to understand. Hose features locking quick disconnects for convenience and safety. Hose also includes strain relief to protect hose and connections from damage.
Hi-Flow™ Triple Hose available with 3/4" blue test pressure hose for quick exhausting
Designed for stack testing of drain, waste, and vent plumbing systems, Clean-Seal® plugs thread into a standard test tee. The bladder is inflated and then water is introduced into the pipe. Upon test completion, deflate the bladder; water travels down the pipe, eliminating test water backsplash.

Ideal for use in hub fittings and in bell-end pipe
An inexpensive method for cleaning new lines prior to line acceptance testing or also for cleaning grease out of existing lines. A better alternative to an expensive jet truck.
Designed to seal monitor wells, these units meet all EPA requirements for locking plugs. They are sized to seal Schedule 40 piping, but 2" and 4" sizes can also seal Schedule 5 pipe.
The Remo® Remote Placement plug provides two advantages—it eliminates the need to enter confined spaces and speeds up the pipe plugging process. The system is safer and less expensive to use than conventional plugging methods because it requires no confined space equipment to simply block sewer flow. A lightweight aluminum pole system (requires pole adapter) or a standard 1¼" iron pipe (when added strength is needed) is used to place the Remo® plug in the sewer system.
Well suited for plugs up to 15"
Greatly reduces possibility of damage to plug due to debris and sharp objects in the pipe. The protective sleeve also protects plugs when the pipe is degraded. Works particularly well in coastal areas where oysters and barnacles are present.
Used for testing gas lines and DWV pipe.
