Few things are as startling as hearing a loud banging or knocking sound echo through your pipes after shutting off a faucet. For homeowners in Gresham and Happy Valley, this unsettling noise is often more than just an annoyance—it’s a warning that your plumbing system needs attention. Left unchecked, pipe banging (commonly called “water hammer”) can damage your plumbing and lead to costly repairs.
What Causes Pipe Banging?
1. Water Hammer
When water flow is suddenly stopped—like when you close a faucet or a washing machine valve—the momentum of the water can cause a shockwave. This shock rattles pipes, creating that distinctive bang.
2. Loose or Unsecured Pipes
Pipes that aren’t anchored properly can shift and knock against studs or walls when water rushes through. This is especially common in older homes.
3. High Water Pressure
Excessive water pressure puts unnecessary stress on pipes and fixtures, causing vibrations and banging noises. It can also shorten the lifespan of appliances and fixtures.
4. Air Bubbles in the Line
Air pockets can become trapped in your plumbing, leading to rattling or knocking sounds as water passes by.
Why You Shouldn’t Ignore Pipe Noises
- Potential Damage: Repeated banging stresses joints and fittings, which can eventually lead to leaks.
- Appliance Strain: High pressure and water hammer can damage dishwashers, washing machines, and water heaters.
- Safety Concerns: Loose pipes may weaken further, resulting in leaks behind walls or under floors.
Quick Homeowner Checks
If your pipes are making noise, here are a few things you can check:
- Inspect Pipe Anchors: Look under sinks and in basements for pipes that aren’t secured properly. Adding clamps may help.
- Check Water Pressure: If your water pressure is above 60 psi, consider installing a regulator.
- Drain the System: Sometimes flushing your pipes helps release trapped air bubbles.
If the banging persists, it’s time to call a professional plumber.
