Installing a Water Hammer Arrestor in Your Kitchen

Installing a water hammer arrestor in your kitchen can help prevent the annoying and potentially damaging effects of water hammer. Water hammer is a common plumbing issue that occurs when the flow of water is suddenly stopped or redirected, causing a loud banging or knocking noise in the pipes. This can lead to damage to the plumbing system over time if left untreated. By installing a water hammer arrestor, you can effectively eliminate or reduce the occurrence of water hammer, ensuring a quieter and more efficient plumbing system in your kitchen. In this comprehensive guide, we will walk you through the process of installing a water hammer arrestor in your kitchen, providing step-by-step instructions and valuable insights to help you successfully complete the installation.

1. Understanding Water Hammer

Before diving into the installation process, it is important to have a clear understanding of what water hammer is and how it occurs. Water hammer is a hydraulic shock that happens when the flow of water in a pipe is suddenly stopped or redirected. This abrupt change in flow causes a pressure surge, resulting in a loud banging or knocking noise in the pipes. Water hammer can occur in any plumbing system, including your kitchen, and is often caused by:

  • Closing a valve too quickly
  • Turning off a faucet abruptly
  • Malfunctioning or faulty plumbing fixtures
  • High water pressure

Understanding the causes of water hammer can help you identify potential issues in your kitchen plumbing system and take appropriate measures to prevent or mitigate its effects.

2. Choosing the Right Water Hammer Arrestor

When it comes to installing a water hammer arrestor in your kitchen, it is crucial to choose the right type and size of arrestor for your specific needs. Water hammer arrestors come in various sizes and configurations, and selecting the correct one is essential for optimal performance. Here are some factors to consider when choosing a water hammer arrestor:

  • Water pressure: Determine the water pressure in your kitchen plumbing system to ensure that the chosen arrestor can handle the pressure effectively.
  • Pipe size: Measure the diameter of the pipes in your kitchen to select an arrestor that fits properly.
  • Type of arrestor: There are different types of water hammer arrestors available, including piston-type, diaphragm-type, and air chamber arrestors. Each type has its own advantages and disadvantages, so choose the one that best suits your needs.

  • Water hammer arrestor: Choose the appropriate type and size based on your needs.
  • Pipe cutter: Used to cut the pipes to the desired length.
  • Adjustable wrench: Used to tighten and secure the fittings.
  • Teflon tape: Used to create a watertight seal between the fittings.

Having these tools and materials ready will save you time and effort during the installation process, allowing you to complete the task efficiently.

4. Installing the Water Hammer Arrestor

Now that you have a good understanding of water hammer, have chosen the right water hammer arrestor, and gathered all the necessary tools and materials, it’s time to proceed with the installation. Follow these step-by-step instructions to install the water hammer arrestor in your kitchen:

  1. Turn off the main water supply: Before starting any plumbing work, it is important to shut off the main water supply to your kitchen. Locate the main shut-off valve and turn it clockwise to close it.
  2. Drain the water lines: Open all the faucets in your kitchen to drain any remaining water from the pipes. This will prevent water from spraying out when you cut the pipes.
  3. Measure and mark the pipe: Use a measuring tape to determine the appropriate location for installing the water hammer arrestor. Mark the pipe at this point using a marker or pencil.
  4. Cut the pipe: Use a pipe cutter to cut the pipe at the marked location. Make sure to cut the pipe cleanly and squarely for a proper fit.
  5. Install the fittings: Attach the necessary fittings to the ends of the cut pipe. Apply Teflon tape to the threaded ends of the fittings to create a watertight seal.
  6. Attach the water hammer arrestor: Connect the water hammer arrestor to the fittings using an adjustable wrench. Make sure the arrestor is securely tightened to prevent any leaks.
  7. Secure the arrestor: Use plumber’s tape to secure the water hammer arrestor to the wall or cabinet. This will provide additional stability and prevent the arrestor from moving or vibrating.
  8. Turn on the water supply: Once the water hammer arrestor is securely installed, turn on the main water supply to your kitchen. Check for any leaks or unusual noises in the plumbing system.

  • Check for leaks: Periodically inspect the water hammer arrestor for any signs of leaks. If you notice any leaks, tighten the fittings or replace any damaged components.
  • Flush the system: Flushing the plumbing system can help remove any sediment or debris that may accumulate over time. Simply open all the faucets in your kitchen and let the water run for a few minutes.
  • Monitor water pressure: Keep an eye on the water pressure in your kitchen. If you notice any sudden changes or fluctuations, it may indicate a problem with the water hammer arrestor or the plumbing system.
