The sudden “bang” or “clunk” you hear when a faucet is turned off quickly, or a washing machine valve slams shut, is known as water hammer. It’s not just annoying; it can be damaging to your plumbing system. Understanding if Are Hammer Arrestors Required By Code is crucial for homeowners and contractors alike to ensure the longevity and safety of water supply systems.
Decoding the Code Are Hammer Arrestors Required?
The question of whether or not Are Hammer Arrestors Required By Code doesn’t have a simple yes or no answer. Building codes, typically based on model codes like the Uniform Plumbing Code (UPC) or the International Plumbing Code (IPC), vary by locality and may have specific requirements or exceptions. Generally, these codes address water hammer and the need for protection against it, but the specific methods and applications often depend on factors such as the building type, water pressure, and the fixture being served. Therefore, it’s vitally important to consult your local plumbing code to determine the specific regulations in your area.
To understand the code better, let’s break down some common considerations:
- High Water Pressure: Systems with excessively high water pressure are more prone to water hammer and often require arrestors.
- Quick-Closing Valves: Fixtures with solenoid valves, like washing machines and dishwashers, create abrupt water flow stops, necessitating arrestors.
- Building Type: Multi-story buildings and commercial properties often have stricter requirements due to more extensive plumbing systems.
Methods to mitigate water hammer and requirements for them can vary. Here are examples of methods and locations where they are typically used:
| Method | Typical Location |
|---|---|
| Air Chambers | Near individual fixtures |
| Mechanical Arrestors | Main water lines, near fixture supply stops |
Navigating the complexities of plumbing codes can be daunting, but it’s essential for ensuring a safe and compliant plumbing system. Don’t rely on guesswork when it comes to protecting your pipes!
For specific guidance on whether hammer arrestors are required in your area and how to properly install them, consult your local plumbing code or a qualified plumbing professional. Contact your local building department or plumbing inspector to get clarity on your area’s current regulations and the most up-to-date requirements.
