LEHRY WATER HAMMER ARRESTORS Is The Term Used To Define The Destructive Forces, Pounding Noises And
Vibration Which Develop In A Piping System When A Column Of Non-Compressible Liquid Flowing Through A Pipe Line
Is Stopped Abruptly. The Tremendous Forces Generated At The Point Of Stoppage Can Be Compared, In Effect, To That
Of An Explosion

 

The LIV-WHA-CP-001 Water Hammer Arrestors Are Designed To Eliminate This Effect. It Features Construction To
Comply With Requirements.
Dishwashers, Clothes Washers, Fast Closing Positive Shutoff Valves Incorporated In The System All Contribute To

Precharged, Permanent Sealed Air Chamber To Absorb The Shock. The Sealed Chamber Prevents The Loss Of Air To
The Water And Assures Long And Trouble-Free Life.
