During an extended water outage, which pipeline materials are approved for temporary connections?

• A. Fire Hoses or Rubber Hoses
• B. PVC or Polyethylene
• C. Steel or Fire Hose
• D. Polyethylene or Rubber Hoses

Answer: (B)

When you’re setting up a temporary bypass during an extended water outage, you must use pipe materials that are approved for potable water and suitable for temporary connections. PVC and polyethylene fit this requirement because they are specifically designed and rated for drinking-water systems, they resist corrosion, can handle the typical pressures, and can be disinfected easily. They also come with readily available fittings for quick, temporary installations, which is essential when time is critical.

Fire hoses or rubber hoses aren’t intended for potable water distribution as permanent or semi-permanent connections; they lack reliable, long-term pressure ratings and secure fittings, and they pose contamination and leakage risks. Steel, while strong, is heavier and less flexible for rapid temporary deployments and requires more involved connections and disinfection. Rubber-based options aren’t designed for potable-water service either and don’t offer the same predictability in compatibility and sanitation as approved plastics.
