5-Year Hydrostatic Test & Check Valve Replacement

Fairfield Fire Protection recently completed a critical 5-year hydrostatic test on the Fire Department Connection (FDC) at The Shoppes at Ety Village in Lancaster, Ohio. This test, mandated by NFPA 25 standards, verifies the integrity of fire protection systems relied upon by first responders in the event of a fire.

What the Test Involves

Hydrostatic testing involves pressurizing the FDC piping system to 150 psi and observing it for any signs of leaks, pressure loss, or blockages. This process ensures that the entire connection remains structurally sound and free of obstructions — so firefighters have immediate and uninterrupted access to water when seconds count.

What We Found

During this inspection, our team discovered a failed check valve — a crucial component that prevents water from flowing backward into the supply line. A malfunctioning check valve compromises the reliability of the FDC and poses a serious hazard during emergency response.

We immediately replaced the damaged valve, and the system was re-tested with successful results:

  • New check valve installed
  • No leaks or pressure loss observed
  • FDC restored to full functionality and code compliance
  • Pressure gauge during the 150 psi hydrostatic test
  • Failed check valve removed from the fire department connection
  • Replacement check valve installed and re-tested

Why It Matters

Routine inspections like this are more than regulatory obligations — they are a commitment to public safety and operational readiness. Need to schedule your NFPA 25 testing?
