Water hammer, a common plumbing issue, occurs when a sudden stop or change in water flow causes pipes to shake or produce a loud banging noise. Left unaddressed, water hammer can damage your plumbing system and lead to costly repairs. This guide explores the causes of water hammer, the risks it poses, and effective ways to fix and prevent it in your Alexandria home.

What Causes Water Hammer?

1. Sudden Water Flow Changes

Water hammer typically occurs when valves or faucets are closed quickly, causing water to slam against the pipe walls.

• Common Culprits:
  • Quick-closing valves in washing machines or dishwashers.
  • Fast faucet shut-offs.

2. High Water Pressure

Excessive water pressure amplifies the force of water hitting the pipes, making water hammer more likely. (Go here)

• Normal Pressure Range: 40–60 psi.
• High Pressure: Above 80 psi increases the risk of pipe damage.

3. Lack of Air Cushions

Air chambers or cushions are designed to absorb the shock of moving water. If they fill with water or fail, water hammer occurs.

• Reasons for Failure:
  • Debris blocking the chamber.
  • Long-term wear and tear.

4. Poor Pipe Support

Inadequately secured pipes can move and vibrate more during water flow changes, exacerbating water hammer.

Potential Damage Caused by Water Hammer

1. Pipe Damage
   • Repeated shocks can weaken pipes, leading to cracks or bursts.

2. Joint and Fitting Failure
   • The force from water hammer can loosen pipe connections, causing leaks.

3. Appliance Damage
   • Valves in dishwashers and washing machines can fail due to repeated pressure surges.

4. Noise Pollution
   • Persistent banging sounds are disruptive and indicate a plumbing system under stress.

How to Fix and Prevent Water Hammer

1. Install Water Hammer Arrestors

Water hammer arrestors are devices that absorb the shock caused by water flow changes.

• Where to Install:
  • Near quick-closing valves.
  • At the source of the noise, such as faucets or appliances.

2. Adjust Water Pressure

Lowering your home’s water pressure can reduce the intensity of water hammer.

• How to Adjust:
  • Install a pressure-reducing valve (PRV).
  • Test water pressure using a pressure gauge.

3. Secure Loose Pipes

Properly secure pipes with brackets or straps to minimize movement and vibration.

• Best Practices:
  • Space supports every 6–8 feet for horizontal pipes.
  • Use cushioned pipe clamps to reduce noise.

4. Drain Air Chambers

If air chambers are filled with water, draining your plumbing system can restore their functionality.

• Steps:
  • Turn off the main water supply.
  • Open faucets to allow water to drain out.
  • Turn the water supply back on to refill the chambers with air.

5. Schedule Regular Maintenance

Routine plumbing inspections can identify and address issues like high pressure or inadequate supports before they escalate.
