General Pipe Cleaners' Kinetic Water Ram generates a shock wave to open clogged pipes. It fires an environmentally safe compressed air charge into a clogged sink, tub or floor drain with only 2 percent loss of power. Built into the Ram is a self-contained pump and pressure gauge so the operator can select the right amount of force for the job. The new Model-G has a redesigned triggering device that gives greater impact when the compressed air charge is released. The grip handle has been enlarged for a more comfortable operation.
