Understanding Water Hammer and Its Effects on Plumbing
Definition of Water Hammer
Water hammer is a plumbing phenomenon that occurs when a water valve is suddenly closed, causing a pressure surge or wave in the pipes.
This pressure wave can cause a loud banging or thudding noise, which is commonly referred to as water hammer or hydraulic shock.
Common Causes of Water Hammer in Home Plumbing
The primary cause of water hammer is the abrupt stopping of water flow, which can happen when appliances like dishwashers or washing machines shut off their water intake quickly.
Other causes include high water pressure, having pipes that are not securely anchored, or the presence of quick-closing valves in the plumbing system.
Negative Impacts of Water Hammer on Pipes and Appliances
Water hammer can lead to various negative impacts on your plumbing system. It can cause pipes to move, resulting in leaks at the joints or even pipe bursts.
This shockwave can also damage appliances connected to the plumbing system, reducing their lifespan and leading to costly repairs or replacements.
Identifying the Signs of Water Hammer in Your Home
Signs of water hammer include loud banging noises coming from the pipes, especially when using appliances like dishwashers. You may also notice pipes shaking or vibrating, or see visible signs of damage such as leaks or dents in the pipes.
The Role of Water Hammer Arrestors
Explanation of How Water Hammer Arrestors Work
Water hammer arrestors are devices designed to absorb the shockwave created by the sudden cessation of water flow, thereby preventing water hammer. They typically consist of a chamber filled with air or gas, which acts as a cushion against the water pressure wave.
The Benefits of Installing a Water Hammer Arrestor
Installing a water hammer arrestor can protect your home’s plumbing by reducing the stress on pipes and preventing the loud noises associated with water hammer. This leads to a quieter home environment and can save you money on plumbing repairs and appliance maintenance in the long run.
