That rhythmic banging or knocking coming from your pipes? It’s not a poltergeist, but it can be just as unsettling. These noises, often called “water hammer,” are usually a sign of a problem in your plumbing system that needs attention. Ignoring it could lead to more significant issues down the line.
Let our Long Beach Plumbing Experts help you explore the common culprits behind noisy pipes and how to address them.
The Usual Suspects: Why Your Pipes are Making Noise
Several factors can cause banging or knocking sounds in your pipes:
Water Hammer: This is the most common cause. Water hammer occurs when water moving rapidly through your pipes suddenly stops. The inertia of the water creates a pressure surge, causing the pipes to bang against surrounding structures. This often happens when you quickly turn off a faucet or appliance.
Loose Pipes: Pipes that aren’t properly secured can rattle and bang against framing members or other pipes when water flows through them. This is especially common in older homes or after renovations.
High Water Pressure: Excessive water pressure in your system can exacerbate water hammer and cause pipes to vibrate and knock.
Air in the Pipes: Air trapped within your pipes can create noisy vibrations as the water flows around it. This is often indicated by gurgling sounds in addition to banging.
Expansion and Contraction: Pipes expand and contract with changes in temperature. If they’re not properly installed or supported, this movement can cause them to bang against other objects.
Clogged Pipes: While not always directly causing banging, severely clogged pipes can create increased pressure and contribute to water hammer.
Troubleshooting and Solutions:
Identify the Source: Try to pinpoint the location of the noise. This will help you narrow down the potential causes.
Check Water Pressure: Use a pressure gauge to measure your water pressure. If it’s too high (typically above 80 psi), contact your water company to have it adjusted.
Inspect for Loose Pipes: Look for any pipes that appear loose or improperly supported. Tighten any loose connections or add support straps where necessary.
Address Air in the Pipes: If you suspect air in the pipes, you might need to bleed the air out of the system. This usually involves opening a faucet at the highest point in your house and letting the water run until the air is expelled.
Install Water Hammer Arrestors: These inexpensive devices are specifically designed to absorb the shock waves caused by water hammer. They’re installed on the water supply lines near faucets and appliances. This is often the most effective solution for
persistent water hammer.
Consider Pipe Insulation: Insulating your pipes can help reduce noise caused by expansion and contraction.
Professional Help From A Local Long Beach Plumber: If you’re unable to identify or resolve the problem yourself, it’s best to call a qualified Long Beach Plumbing Company. They have the expertise and tools to diagnose and repair more complex plumbing issues.
Preventing Future Noise Problems:
Proper Installation: Ensure that new pipes are installed correctly and securely fastened.
Regular Maintenance: Regularly check your plumbing system for leaks, loose connections, and other potential problems.
Avoid Sudden Water Flow Changes: Try to turn faucets on and off gradually to minimize water hammer.
Noisy pipes can be a nuisance, but with some investigation and the right approach, you can usually identify and resolve the underlying cause. Remember, addressing the problem promptly can save you from more significant and costly repairs down the road.
