At Next Plumbing in Cape Coral, FL, we understand the frustration of dealing with noisy pipes. That constant banging and knocking can be incredibly disruptive and even a bit unsettling. But don’t worry, you’re not alone! Knocking pipes are a common plumbing issue with several potential causes. In this guide, we’ll explore the most frequent culprits and why it’s crucial to call in the plumbing professionals at Next Plumbing for a proper diagnosis and solution.
Common Causes of Knocking Pipes
- Water Hammer: This is a common culprit, especially in older homes. When a valve suddenly closes, the rushing water slams against the valve, creating shockwaves that shake the pipes.
- High Water Pressure: Excessive water pressure can cause pipes to vibrate and knock against surrounding structures.
- Loose Pipes: Vibrating pipes can also occur if they’re not securely fastened.
- Expanding/Contracting Hot Water Pipes: As hot water passes through, pipes expand and can rub against nearby surfaces, causing knocking sounds.
- Sediment Buildup in Water Heater: This can lead to banging noises, even when no water is running, as steam bubbles escape from the sediment.
Water Hammer: A Closer Look
Water hammer is a serious issue. Older homes often rely on air chambers to cushion the impact of water hammer, but these can become ineffective over time. This is where water hammer arrestors come in. These devices are designed to absorb the shockwaves and prevent damage to your plumbing system.
High Water Pressure: The Impact
While Cape Coral typically has moderate water pressure, excessive pressure can still cause problems. High pressure can stress the pipes, leading to leaks and premature wear and tear. It can also increase the risk of water hammering.
Loose Pipes: A Vibration Issue
Loose pipes can vibrate and knock against walls, floors, or other pipes, creating a variety of unsettling noises. This can be exacerbated by high water pressure.
Expanding/Contracting Hot Water Pipes
Hot water causes pipes to expand slightly. If these pipes are not properly supported or insulated, they can rub against surrounding structures, creating knocking sounds.
Sediment Buildup in Water Heater
Over time, sediment builds up at the bottom of your water heater. As the water heats, steam bubbles escape from the sediment, creating banging noises.
