Kinetic Liner Water Ram

There's a compact, light weight tool for quickly opening clogged sinks, toilets and tubs. It handles rust, grease, sediment, and scale in lines up through 4" in diameter. The Kinetic Water Ram uses a burst of compressed air that drives a shock wave (kinetic energy) through water to break up stoppage. It's particularly useful when the stoppage is on the far side of a drum trap or series of tight bends, since the shock wave can travel around bends without losing its force.

The Ram has a self-contained pump and pressure gauge, so you can hit the stoppage with just the right amount of force. You get instant impact with no build-up of pressure in the plumbing system. The force is transmitted through water, so it's not affected by stacks or vents.
