Types of Staple Guns

Water Hammer Arresters

Water hammer arresters (also spelled “water hammer arrestors“) are used to stop the inertia caused by a sudden stop in the flow of water. Have you ever heard a load banging noise when you turn off your water or when the toilet is done filling up? If so, you are hearing what is known as “water hammer“.

Water hammer is the noise that is the result of fast moving water suddenly coming to a stop. When the water is suddenly stopped by shutting off a valve, the inertia causes the plumbing to bang up against a wall, stud or other plumbing. The noise from water hammer can be very load and will reverberate throughout your entire plumbing system and can often be heard throughout the entire home.
