What To Know
- Water hammer, a plumbing phenomenon, occurs when water flowing through pipes is abruptly stopped, causing a pressure surge.
- Worn or defective valves or faucets can cause water to stop flowing abruptly, increasing the likelihood of water hammer.
- You can purchase a water hammer arrestor at a hardware store and install it yourself.
Water hammer, a plumbing phenomenon, occurs when water flowing through pipes is abruptly stopped, causing a pressure surge. This sudden surge can generate a loud banging or hammering sound within the pipes, hence the name “water hammer.” It’s a common issue that can damage plumbing fixtures, pipes, and appliances.
Causes of Water Hammer
The primary cause of water hammer is the rapid closure of valves or faucets. When water is flowing through a pipe, it possesses momentum. When the flow is abruptly stopped, this momentum creates a pressure wave that travels through the pipes. This pressure wave can reach high levels, causing damage to the plumbing system.
Other factors that can contribute to water hammer include:
- Long pipe runs: The longer the pipe run, the more time the pressure wave has to build up momentum.
- High water pressure: Higher water pressure exacerbates the effects of water hammer.
- Loose or unsecured pipes: Unsecured pipes can amplify the vibrations caused by water hammer.
- Faulty valves or faucets: Worn or defective valves or faucets can cause water to stop flowing abruptly, increasing the likelihood of water hammer.
Signs of Water Hammer
The most noticeable sign of water hammer is the loud banging or hammering sound within the pipes. Other symptoms include:
- Leaking pipes or fixtures: The pressure surge can weaken pipe joints and cause leaks.
- Damaged appliances: Water hammer can damage washing machines, dishwashers, and other appliances connected to the plumbing system.
- Reduced water pressure: Severe water hammer can restrict water flow and reduce pressure throughout the home.
Consequences of Water Hammer
Water hammer can have several negative consequences:
- Damage to pipes: The pressure surge can cause pipes to burst or crack.
- Damage to fixtures: Water hammer can loosen or damage faucets, toilets, and other fixtures.
- Damage to appliances: Water hammer can damage the water inlet valves and other components of appliances.
- Noise pollution: The loud banging sounds can be disruptive and annoying.
Preventing Water Hammer
There are several measures you can take to prevent water hammer:
- Install water hammer arrestors: These devices absorb the pressure surge and prevent it from damaging the plumbing system.
- Use slow-closing valves: Gradual valve closure reduces the momentum of the water flow, minimizing the pressure surge.
- Secure pipes properly: Ensure pipes are securely fastened to prevent movement and vibration.
- Inspect and maintain valves and faucets: Regularly check valves and faucets for leaks or defects that could cause water hammer.
- Reduce water pressure: If possible, adjust the water pressure regulator to reduce the overall pressure in the plumbing system.
DIY Solutions for Water Hammer
If you experience water hammer, there are some DIY solutions you can try:
- Tap the pipes: Gently tap the pipes where the banging sound occurs. This can sometimes dislodge air bubbles or debris that may be causing the problem.
- Open and close faucets slowly: Practice opening and closing faucets gradually to reduce the pressure surge.
- Install a water hammer arrestor: You can purchase a water hammer arrestor at a hardware store and install it yourself.
When to Call a Plumber
If the DIY solutions do not resolve the water hammer issue, it’s advisable to contact a licensed plumber. A plumber can:
- Diagnose the cause of water hammer: Determine the specific cause of the problem and recommend appropriate solutions.
- Install or repair water hammer arrestors: Install or replace water hammer arrestors to prevent future damage.
- Repair damaged pipes or fixtures: Fix any leaks or damage caused by water hammer.
