Water hammer is a frustrating and potentially damaging issue in plumbing systems, causing loud banging noises and even pipe damage. For businesses relying on stable water pressure, such as construction projects or building material wholesalers, this problem can lead to costly repairs and operational delays. The good news is, a pressure reducing valve can play a key role in mitigating water hammer. But how effective is it? Let’s find out.
Yes, a pressure reducing valve can help reduce water hammer by maintaining consistent water pressure. By preventing sudden pressure spikes, it minimizes the shockwaves that cause the banging noise and potential damage to your plumbing system.
Understanding how a pressure reducing valve works and its role in preventing water hammer is essential for maintaining a reliable plumbing system. In this article, we’ll explore what valves prevent water hammer, how to solve the problem, and whether reducing water pressure can stop it altogether. Keep reading to learn how to protect your system and ensure smooth operations.

What Valve Prevents Water Hammer?
Several types of valves can help prevent water hammer, but the most effective ones are designed to control water pressure and flow. Here are the key valves to consider:
- Pressure Reducing Valve: A water pressure reducing valve regulates high water pressure, ensuring it stays within safe limits. By maintaining consistent pressure, it reduces the risk of sudden pressure spikes that cause water hammer.
- Water Hammer Arrestor: This specialized valve absorbs shockwaves caused by sudden changes in water flow. It’s often installed near quick-closing valves to prevent water hammer.
- Check Valve: A check valve allows water to flow in one direction only, preventing backflow that can contribute to water hammer.
- Thermostatic Mixing Valve: While primarily used for temperature control, a thermostatic mixing valve can also help stabilize water flow, indirectly reducing the risk of water hammer.
For businesses like yours, investing in high-quality valves, such as IVALVECRAFT’s brass thermostatic radiator valves or pressure reducing valves, can significantly improve system reliability. These valves are designed to handle high pressure and provide stable performance, ensuring your plumbing system operates smoothly.
How to Solve Water Hammer Problem?
Solving water hammer requires a combination of proper equipment and system maintenance. Here are some effective solutions:
- Install a Pressure Reducing Valve: A domestic water pressure reducing valve can regulate water pressure, preventing the sudden spikes that cause water hammer. Ensure the valve is properly calibrated for your system’s needs.
- Use Water Hammer Arrestors: Installing water hammer arrestors at key points in your plumbing system can absorb shockwaves and prevent banging noises.
- Secure Loose Pipes: Loose pipes can amplify the effects of water hammer. Use pipe clamps or brackets to secure them and reduce vibrations.
- Inspect and Maintain Valves: Regularly check valves like brass safety valves and thermostatic mixing valves for wear and tear. Replace any faulty components to maintain system stability.
- Adjust Water Pressure: If your water pressure is too high, reducing it to a safe level can minimize the risk of water hammer. A water pressure regulator can help achieve this.
For businesses like yours, implementing these solutions can prevent costly repairs and downtime. IVALVECRAFT offers a range of high-quality valves and components designed to address water hammer and other plumbing issues effectively.
Will Reducing Water Pressure Stop a Water Hammer?
Reducing water pressure is one of the most effective ways to stop water hammer. High water pressure increases the force of water flow, making sudden stops more impactful and creating shockwaves. By installing a water pressure reduction valve, you can maintain consistent pressure and minimize the risk of water hammer.
However, reducing water pressure alone may not completely eliminate water hammer, especially if other factors like quick-closing valves or loose pipes are present. Combining pressure reduction with other solutions, such as water hammer arrestors and regular maintenance, provides the best results.
For businesses like yours, ensuring stable water pressure is crucial. IVALVECRAFT’s pressure reducing valves and brass thermostatic radiator valves are designed to deliver reliable performance, helping you maintain a stable and efficient plumbing system.

Summary
Water hammer can cause significant damage to your plumbing system, but it’s a problem that can be managed with the right solutions. A pressure reducing valve plays a key role in preventing water hammer by maintaining consistent water pressure. Combining this with other measures, such as water hammer arrestors and regular maintenance, ensures your system runs smoothly.
