WATER STORAGE

overflow and warning pipe correct installation

OVERVIEW

Correctly installing your overflow and warning pipes is critical for compliance, safety, and long-term performance of your cold water storage tank.

Lets discuss: 

  • The correct positioning of warning vs. overflow pipes

  • How to avoid common installation mistakes

  • What regulations you need to follow for compliance

💡 Quick Tip: The warning pipe should always activate before the overflow — if not, your system isn’t compliant.

Why correct plumbing matters

Incorrect installation of overflow and warning pipes can lead to undetected leaks, which may cause:

  • Structural damage
  • Mould growth
  • Health and safety issues
  • Costly repairs and operational downtime

Early warning signs often include a dripping overflow pipe — typically caused by faults in the tank’s float valve, inlet mechanism, or other components. If ignored, these can lead to significant flooding if excess water isn’t safely discharged.

How Overflow and warning pipes work

The warning pipe is an integral safety feature of a water storage tank. Its primary purpose is to alert personnel to abnormal water levels by visibly discharging water before the main overflow is activated.

If the issue causing the rising water level is not addressed, the water will eventually reach the main overflow pipe. At this point, the overflow system must be properly installed to redirect excess water away from critical areas, preventing flooding and additional damage.

Key Functions of Overflow Piping Systems:

  1. Early Detection: Warning pipes provide a visual or audible signal of system faults.
  2. Controlled Overflow: The overflow pipe ensures that excess water exits safely, reducing risks to property and infrastructure.
  3. Regulatory Compliance: Proper installation and maintenance ensure adherence to WRAS guidelines and other local regulatory standards.

Preventative Maintenance & Common Issues

Routine checks and early repairs can save you major costs and downtime.

Do this regularly:

  • Check for dripping overflow pipes or pooled water.

  • Inspect for blocked or restricted pipework.

  • Ensure proper valve function and pipe placement.

Avoid these common faults:

  • Overflow pipes not discharging visibly

  • Leaks going unnoticed inside buildings

  • Inlet valves stuck open, causing tanks to overfill
