Water hammer arrestors are an important plumbing device used to reduce the shock of water pressure changes in a system. They are often installed in homes and businesses to prevent damage from water hammer, which is caused when the velocity of water inside a pipe suddenly changes. The placement of water hammer arrestors is crucial for them to be effective. In this article, we will discuss where water hammer arrestors should be installed in order to provide optimal protection against water hammer.Water hammer is a pressure surge caused by a sudden change in the velocity of water flow within a pipe. It can occur when a valve or faucet is closed quickly, or when there is a rapid change in the pressure of the water supply. The result can be loud banging noise and damage to pipes, valves, and other components of the plumbing system. It is important to arrest water hammer because it can cause wear and tear on piping systems, increase energy costs due to increased pressure losses, and even cause flooding from broken pipes.
What is a Water Hammer Arrestor?
A water hammer arrestor is a device used to prevent the loud banging or thumping sound that can occur in plumbing pipes when a valve is closed quickly. The water hammer arrestor works by providing an air cushion or air chamber which absorbs the energy from the moving water and prevents it from causing damage to the pipes or fixtures. This type of device is often used in homes and businesses to reduce noise caused by sudden changes in water pressure, such as when a washing machine shuts off its supply valve. The installation of a water hammer arrestor can also help to reduce the amount of wear and tear on pipes and other plumbing components.
Water hammer arrestors are typically installed near faucets, valves, and other fixtures where sudden changes in water pressure may occur. It is important to choose an appropriate size for the water hammer arrestor based on the size of piping within the system as well as the amount of pressure expected in the system. Proper installation of a water hammer arrestor is essential for it to work properly and ensure maximum protection against excessive noise and pipe damage.
Understanding the Different Types of Water Hammer Arrestors
Water hammer arrestors are devices used to prevent or reduce the pressure surge that can result from the sudden stoppage of a liquid flowing in a pipe. They are commonly used in plumbing systems and industrial applications to help control water pressure and reduce the risk of damage. There are several types of water hammer arrestors available, and each type has its own advantages and disadvantages. In this article, we will discuss the different types of water hammer arrestors and their uses.
The most common type of water hammer arrestor is a mechanical device that uses a shock absorber to dampen the pressure surge caused by sudden stoppage. Mechanical water hammer arrestors are usually installed at the end of the pipe, just before the shut-off valve. They work by dissipating energy from the incoming liquid flow, and can provide effective protection against high-pressure surges. The downside to this type of arrestor is that it can be quite noisy and require regular maintenance.
Another type of water hammer arrestor is an air chamber device. This type utilizes an air pocket to absorb some of the energy created by a pressure surge. The air pocket acts as a buffer between the pipe and shut-off valve, reducing risk of damage from high-pressure surges. Air chamber devices can be quite effective but they do require some maintenance as well as periodic adjustments for maximum efficiency.
A third option is an electronic water hammer arrestor which utilizes an electric current to dampen pressure surges caused by sudden stoppage. This type is typically more expensive than other types but it does offer superior performance in terms of protection from high-pressure surges. Electronic water hammer arrestors also have fewer maintenance requirements than mechanical or air chamber devices.
No matter what type you choose, it’s important to understand how each one works in order to ensure your system is properly protected against high-pressure surges caused by sudden stoppages in liquid flow. With proper installation and maintenance, any type of water hammer arrestor can provide effective protection for your system and help reduce risk of damage due to high-pressure surges.
Where Should Water Hammer Arrestors Be Installed?
Water hammer arrestors help to protect plumbing systems from the damaging effects of water hammer, a phenomenon that occurs when a valve is quickly closed, causing a pressure surge. Installing water hammer arrestors at key points in the system will help to reduce the chance of damage.
In general, water hammer arrestors should be installed on any line that contains a shutoff valve, such as toilets and washing machines. This is because when these valves are closed quickly, it can cause a pressure surge that can damage pipes and other components in the system.
Water hammer arrestors should also be installed on any line where there is a change in direction or elevation. These changes can also cause pressure surges and should be mitigated with an appropriate water hammer arrestor.
Finally, it is important to install water hammer arrestors at any point where there is an abrupt change in flow rate or velocity. These changes can also cause pressure surges and should be addressed with an appropriate water hammer arrestor.
In summary, water hammer arrestors should be installed on lines that contain shutoff valves, lines with changes in direction or elevation, and lines with abrupt changes in flow rate or velocity. By installing these devices at key points in the system, it will help to ensure that plumbing systems are protected from the damaging effects of water hammer.
