DIY Plumbing Dilemma: Exploring the Feasibility of Sideways Water Hammer Arrestor Placement
What To Know
- Water hammer occurs when a fast-moving water flow is abruptly stopped, creating a shock wave that reverberates through the plumbing system.
- Regardless of the orientation chosen, it is crucial to follow proper installation guidelines to ensure the effectiveness and longevity of the water hammer arrestor.
- The question of whether water hammer arrestors can be installed on their side requires careful consideration of the type of arrestor used.
Water hammer arrestors play a crucial role in plumbing systems, preventing the damaging effects of water hammer. As homeowners embark on DIY projects or encounter plumbing issues, a common question arises: “Can water hammer arrestors be installed on their side?” In this comprehensive blog post, we will delve into the intricacies of this topic, exploring the technicalities, implications, and best practices surrounding the installation of water hammer arrestors.
Understanding Water Hammer
Before addressing the installation orientation of water hammer arrestors, it is essential to understand the phenomenon they are designed to combat. Water hammer occurs when a fast-moving water flow is abruptly stopped, creating a shock wave that reverberates through the plumbing system. This shock wave can cause pipes to rattle, joints to loosen, and fixtures to fail.
The Role of Water Hammer Arrestors
Water hammer arrestors are devices installed in plumbing systems to absorb and dissipate the energy of water hammer. They consist of a chamber filled with air or gas that compresses when the shock wave passes through, effectively cushioning the impact.
Can Water Hammer Arrestors Be Installed on Their Side?
The answer to this question depends on the type of water hammer arrestor used.
Diaphragm-Type Arrestors
Diaphragm-type water hammer arrestors have a flexible diaphragm that separates the water chamber from the air chamber. These arrestors can be installed either vertically or horizontally (on their side). However, it is recommended to install them vertically to ensure proper operation and longevity.
Piston-Type Arrestors
Piston-type water hammer arrestors use a piston to separate the water and air chambers. Unlike diaphragm-type arrestors, piston-type arrestors must be installed vertically. If installed on their side, the piston may not move freely, compromising the arrestor’s effectiveness.
Vertical vs. Horizontal Installation: Pros and Cons
Vertical Installation
- Pros:
- Ensures proper operation of both diaphragm- and piston-type arrestors
- Facilitates the release of trapped air
- Reduces the risk of premature failure
- Cons:
- Requires more space
- May not be aesthetically pleasing in certain locations
Horizontal Installation
- Pros:
- Saves space
- Can be concealed in tight spaces or behind walls
- May be more aesthetically appealing
- Cons:
- Not suitable for piston-type arrestors
- May trap air and reduce the arrestor’s effectiveness
- Increases the risk of premature failure
Proper Installation Guidelines
Regardless of the orientation chosen, it is crucial to follow proper installation guidelines to ensure the effectiveness and longevity of the water hammer arrestor:
- Install the arrestor as close as possible to the source of water hammer (e.g., washing machine, dishwasher)
- Use a pipe wrench to tighten the connections securely
- Ensure that the arrestor is in the correct orientation for its type
- Release any trapped air by opening a nearby faucet
- Test the system by running water through the affected fixtures
Troubleshooting Tips
If you suspect that your water hammer arrestor is not working properly, here are some troubleshooting tips:
- Check for leaks or loose connections
- Release any trapped air
- Replace the arrestor if it is damaged or has failed
Summary
The question of whether water hammer arrestors can be installed on their side requires careful consideration of the type of arrestor used. Diaphragm-type arrestors can be installed horizontally, while piston-type arrestors must be installed vertically. By understanding the implications of horizontal installation, homeowners can make informed decisions and ensure the proper functioning of their plumbing systems.
Questions You May Have
Q: Why is it not recommended to install piston-type water hammer arrestors on their side?
A: Piston-type arrestors require vertical installation to ensure proper piston movement and effectiveness.
Q: What are the benefits of installing water hammer arrestors vertically?
A: Vertical installation facilitates air release, reduces the risk of premature failure, and ensures optimal performance.
Q: How often should water hammer arrestors be replaced?
A: The lifespan of water hammer arrestors varies depending on usage and water quality. However, it is generally recommended to replace them every 5-10 years.
