How to Fix Annoying Water Hammer in Your Shower

That jarring, banging sound coming from your pipes after you turn off your shower? That's water hammer, and it's more than just annoying—it can actually damage your plumbing over time. This article will guide you through understanding the causes and providing practical solutions to eliminate that pesky water hammer in your shower. We'll cover DIY fixes and when to call a professional.

Water hammer occurs when the rapidly flowing water in your pipes suddenly stops. This abrupt halt creates a pressure wave that travels through the pipes, causing the characteristic banging or hammering sound. While the sound itself is unsettling, repeated water hammer can weaken pipes, leading to leaks and potentially more extensive damage.

Understanding the Causes of Water Hammer in Your Shower

Several factors can contribute to water hammer in your shower:

• Sudden Valve Closure: The most common cause is a quick closure of the shower valve. Older valves, especially, may not have a mechanism to slow down the water flow, exacerbating the problem.
• Air Pockets in Pipes: Air trapped within your plumbing system can also contribute to water hammer. When the water flow stops, the air compresses and expands, creating the banging sound.
• Loose Pipes: Pipes that aren't properly secured to the framing can vibrate more easily, amplifying the sound of water hammer.
• Long Pipes: Longer pipes provide more distance for the pressure wave to travel, making the hammering sound more pronounced.
• High Water Pressure: Excessively high water pressure can increase the force of the pressure wave, resulting in more severe water hammer.

DIY Solutions to Fix Water Hammer in Your Shower

Before you call a plumber, try these simple DIY solutions:

• Install Water Hammer Arrestors: These inexpensive devices are specifically designed to absorb the shock waves caused by water hammer. They are typically installed on the pipes leading to the shower valve. You'll need to locate the shut-off valves for your shower and install the arrestors near those valves. Remember to turn off the water supply before working on your plumbing.
• Check and Tighten Pipes: Inspect the pipes leading to your shower for any loose connections or supports. Tighten any loose connections and secure any loose pipes to the framing using pipe clamps or straps.
• Air Chambers/Expansion Tanks: Some plumbing systems have air chambers built into the system. If these chambers are clogged with water, they will not work effectively. However, most modern plumbing systems use pressure-reducing valves and expansion tanks rather than air chambers. Addressing low pressure by checking and cleaning the pressure-reducing valve might help. If it’s an older system, professional help might be needed.

When to Call a Plumber

While many water hammer issues can be resolved with DIY fixes, some situations require professional help:

• Persistent Water Hammer After DIY Attempts: If you've tried the above solutions and the water hammer persists, it's time to call a qualified plumber. They have the expertise to diagnose more complex issues and implement more substantial solutions.
• Significant Leaks or Damage: Any signs of leaks or damage to your pipes necessitate immediate professional attention.
• You're Uncomfortable Working with Plumbing: If you're not comfortable working with plumbing, it's always best to call a professional to avoid further damage.

Fixing water hammer not only eliminates the annoying noise but also safeguards your plumbing system from potential damage in the long run. By understanding the causes and implementing these solutions, you can enjoy a quieter and more reliable shower experience. Remember safety first; always turn off the water supply before attempting any plumbing repairs.
