KR-A-WC General Wire Kinetic Water Ram with Carrying Case 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.General Wire KR-A-WC Kinetic Water Ram with Carrying Case Features:Compact, light weight tool for quickly opening clogged sinks, toilets and tubsHandles rust, grease, sediment, and scale in lines up through 4" in diameterSelf-contained pump and pressure gaugeHit the stoppage with just the right amount of forceGet instant impact with no build-up of pressure in the plumbing systemThe force is transmitted through water, so it's not affected by stacks or ventsIncludes carrying case General Wire KR-A-WC Kinetic Water Ram with Carrying Case Specifications: 16 gauge plated cylinder tested for up to 600 lbs, pressure160 lbs. gearless pressure gauge provides pinpoint pressure controlBuilt-in air compressor easily pumps up to desired pressureFlexible cone seals drains ranging from 1 1/4" to 4"diameterEquipped with Schr der valve for use with external air compressor when clearing difficult stoppages KR-A-WC Includes:Kinetic Water Ram,Complete with Extension Hose,4" Rubber Cone,Five Rubber Plugsand Carrying Case.
