Strange plumbing noises can be unsettling, from the eerie gurgling of a drain to the loud banging of pipes.

For homeowners in Varennes, understanding the causes of these noises and how to address them is key to maintaining a peaceful and functional home. At Plombier Varennes, we’ve helped countless residents diagnose and fix plumbing noises, ensuring their systems run smoothly. In this article, we’ll explore the most common plumbing noises, their causes, and how to eliminate them for good.

Why Plumbing Noises Shouldn’t Be Ignored

Plumbing noises are often a sign of underlying issues, such as:

  • Water Hammer: Caused by sudden changes in water flow, leading to pipe damage.
  • Air in the Pipes: Creating gurgling or whistling sounds.
  • Loose Pipes: Causing rattling or banging noises.
  • Blockages: Leading to gurgling drains or slow water flow.

Ignoring these noises can result in costly repairs and damage to your plumbing system.

Common Plumbing Noises and Their Causes

1. Banging or Hammering Noises

Cause: Water hammer occurs when water flow is suddenly stopped, causing pipes to vibrate or bang against walls.

How to Fix It:

  • Install water hammer arrestors to absorb the shock.
  • Secure loose pipes with foam insulation or pipe straps.

Pro Tip: If the problem persists, call Plombier Varennes to inspect your system.

2. Gurgling Drains

Cause: Air trapped in the pipes or a partial blockage in the drain or sewer line.

How to Fix It:

  • Use a plunger or drain snake to clear the blockage.
  • Pour a mixture of baking soda and vinegar down the drain, followed by hot water.

Pro Tip: If gurgling persists, it may indicate a sewer line issue—contact a professional plumber.

3. Whistling or Screeching Sounds

Cause: High water pressure or a faulty valve, such as a worn-out washer in a faucet or showerhead.

How to Fix It:

  • Install a pressure regulator to reduce water pressure.
  • Replace worn-out washers or cartridges in faucets and showerheads.

Pro Tip: Check your water pressure with a gauge—ideal pressure is between 40-60 psi.

4. Rattling or Vibrating Pipes

Cause: Loose pipes or water pressure that’s too high.

How to Fix It:

  • Secure loose pipes with foam insulation or pipe straps.
  • Adjust your water pressure regulator if necessary.

Pro Tip: Inspect exposed pipes in basements or crawl spaces for signs of movement.

5. Knocking or Ticking Noises

Cause: Thermal expansion in pipes as hot water flows through them.

How to Fix It:

  • Install an expansion tank to accommodate thermal expansion.
  • Insulate pipes to reduce noise and prevent heat loss.

Pro Tip: If the noise is coming from your water heater, it may need servicing or replacement.

How to Prevent Plumbing Noises

1. Maintain Proper Water Pressure

High water pressure can strain your plumbing system and cause noisy pipes.

Pro Tip: Install a pressure regulator to keep water pressure within the recommended range.

2. Secure Loose Pipes

Loose pipes can vibrate or bang against walls, creating noise.

Pro Tip: Use foam insulation or pipe straps to secure pipes and reduce movement.

3. Schedule Regular Maintenance

Regular inspections and maintenance can help identify and address issues before they cause noise or damage.

Pro Tip: Contact Plombier Varennes for annual plumbing checkups.
