A fire hydrant inspection form records the visual condition, mechanical operation, and water-flow capacity of a private hydrant during its annual NFPA 25 checkup, and it gets submitted to the local fire authority as proof of compliance. Filling it out correctly means working through five blocks in order: identification, visual inspection, flow test readings, deficiencies, and inspector certification. Then it goes to the fire prevention bureau, usually through an online portal.
Start With the Form Your Jurisdiction Requires
Local fire departments publish their own versions of the form, and using the wrong one risks having the entire submission rejected. Most departments post the current form on the department website. Portland Fire and Rescue, for example, publishes a Private Fire Hydrants Check Sheet keyed directly to NFPA 25 requirements.1Portland Fire and Rescue. Private Fire Hydrants Check Sheet Per NFPA 25 If yours doesn’t publish one, the state fire marshal’s office can direct you to an accepted template.
Whatever form you use will track NFPA 25’s inspection checklist for water-based fire protection systems.2National Fire Protection Association. NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems Both dry-barrel and wet-barrel hydrants need a visual inspection every year and after each operation, plus an annual flow test under NFPA 25 Section 7.3.2.3NFPA. NFPA 25 Handbook – ITM of Water-Based Fire Protection Systems The five-year flow test people sometimes ask about applies to the fire service main piping rather than the hydrants themselves, though some jurisdictions combine the two into one testing event.
Fill In the Identification Block
The top of the form ties the results to a specific property and hydrant. Typical fields:
- Test date
- Business name and building name
- Street address
- Contact name and phone number
- Total number of hydrants on the system
- Unique hydrant ID number or GPS coordinates
Record the ID or coordinates precisely so emergency responders can find the exact unit later. Vague descriptions like “the one near the parking garage” will not pass a fire marshal’s review. If the property has more than a handful of hydrants, most forms require a separate sheet for each unit or group.
Work Through the Visual Inspection Fields
The visual section mirrors the checklist in NFPA 25 Tables 7.2.2.4 for dry-barrel hydrants and 7.2.2.5 for wet-barrel hydrants.3NFPA. NFPA 25 Handbook – ITM of Water-Based Fire Protection Systems Move through each item methodically and mark it as satisfactory or note the corrective action taken.
For a dry-barrel hydrant, the form covers:
- Accessibility. The hydrant has to be reachable without moving vehicles, fencing, or debris, with vegetation cleared at least three feet in every direction from the barrel.
- Water or ice in the barrel. Standing water inside a dry-barrel hydrant points to a faulty drain, a leaking valve, or a high groundwater table. Note which condition you suspect.
- Drainage. After operation, the barrel should drain completely within 60 minutes. If it doesn’t, indicate whether the drain needs repair or whether groundwater conditions require plugging the drain and pumping.
- Leaks. Check outlets and the top of the hydrant for any water seepage under pressure.
- Barrel cracks. Visible cracks get flagged for immediate repair.
- Outlet caps. Confirm caps are tight, threads are in good condition, and note if lubrication was needed.
- Operating nut. Check for wear. A worn nut can prevent firefighters from opening the hydrant in an emergency.
- Operating wrench. Verify one is available on-site or that the responding fire company carries a compatible wrench.
- Corrosion. Any corrosion that compromises structural integrity gets flagged.
Wet-barrel hydrants share most of the same checklist but skip the drainage and standing-water items, since these hydrants are designed to hold water at all times. If a problem can’t be fixed on the spot, describe it in the deficiency section further down and indicate whether the building owner has been notified.
Record the Three Flow Test Readings
The flow test section is where the form gets technical. Three pressure readings work together to tell the fire authority how much water the hydrant can deliver during a fire.
Static pressure is the reading in the main when no water is flowing. To measure it, remove a 2½-inch cap from the test hydrant, attach your pressure gauge with the air-relief valve open, then slowly open the hydrant valve until water pushes out the relief valve. Close the relief valve and let the gauge stabilize. That stabilized number is your static pressure.4Municipal Technical Advisory Service of Tennessee. Conducting a Fire Flow Test
Residual pressure is the reading on that same gauge while water flows from a nearby hydrant during the test. It drops below the static number because flowing water reduces pressure in the main. Record it simultaneously with the pitot reading.
Pitot pressure captures the velocity of the water stream. Hold the pitot gauge in the center of the discharge stream, about half the outlet diameter away from the opening. The reading feeds directly into the GPM formula.
Record all three values along with the number and size of outlets flowed. NFPA 25 requires you to open the hydrant fully and maintain flow for at least one minute, flushing until the water runs clear of sediment and debris.3NFPA. NFPA 25 Handbook – ITM of Water-Based Fire Protection Systems After closing a dry-barrel hydrant, watch for proper drainage from the barrel and note the result.
Calculate GPM and Enter It on the Form
Most forms include a field for gallons per minute. The standard formula is:
Q = 29.83 × C × d² × √P
Q is the flow in gallons per minute, C is the coefficient of discharge (which depends on the type of outlet), d is the actual diameter of the hydrant orifice in inches, and P is the pitot pressure in psi.5SSLC. Water Based Fire Protection and Water Supply Systems – Fire Flow Calculations The constant 29.83 comes from the physics of water velocity and pressure conversion. If you’re using a diffuser, adjust the coefficient and diameter values for the diffuser rather than the raw outlet.
Note the Color Classification If the Form Asks
Some forms ask you to record the hydrant’s color class. NFPA 291 sets a national color-coding system based on flow capacity measured at 20 psi residual pressure. Hydrant barrels are chrome yellow by default, with bonnets and nozzle caps painted to indicate the flow class:
- Class AA, light blue: 1,500 GPM or greater
- Class A, green: 1,000 to 1,499 GPM
- Class B, orange: 500 to 999 GPM
- Class C, red: less than 500 GPM
Private hydrants are color-coded red regardless of capacity, and non-potable hydrants are violet or light purple. If your flow test places the hydrant in a different class than its paint indicates, note the discrepancy so the fire authority or water utility can repaint the bonnet.
Document Any Deficiencies
A failed hydrant triggers NFPA 25’s impairment procedures, and the form is where that process starts on paper. In the deficiency section, describe the problem clearly. “Main valve will not open” is useful; “needs work” is not. Note whether the building owner or their representative has been notified and who specifically received that notification.
NFPA 25 requires the property owner to designate an impairment coordinator who manages the repair. That coordinator must notify the fire department, insurance carrier, alarm company, and supervisors in affected areas before the impairment begins or as soon as the problem is discovered.3NFPA. NFPA 25 Handbook – ITM of Water-Based Fire Protection Systems An impairment tag has to be placed at each fire department connection, the system control valve, and any other location the fire authority specifies.
When a hydrant is out of service for more than 10 hours in a 24-hour period, the impairment coordinator must arrange at least one of the following: evacuation of the affected area, an approved fire watch, a temporary water supply (such as a large-diameter hose from a working hydrant to the fire department connection), or an approved plan to eliminate ignition sources and limit available fuel. Once repairs pass a follow-up inspection, the tags come off and every party that was notified gets an all-clear.
Sign and Certify at the Bottom
The bottom of the form requires the inspector’s printed name, signature, company name, phone number, and professional certification or license number. Most jurisdictions require private hydrant inspections to be performed by or under the supervision of a licensed fire protection contractor. The specific license designation varies by state, such as a C-16 license in some states. If the form reaches the fire authority without valid credentials, it will likely be returned, and the property stays noncompliant until a properly certified inspector resubmits.
Submit It Through the Right Channel
Where the form goes depends on your jurisdiction. A growing number of fire departments require electronic submission through The Compliance Engine, a third-party portal that aggregates fire protection compliance data.6City of San Diego Official Website. The Compliance Engine Filing fees vary. Some jurisdictions charge around $18 per system type per site, others closer to $37 per report. The contractor performing the inspection typically pays the fee and passes it through in the service cost. If your jurisdiction doesn’t use an online portal, the completed form is mailed or hand-delivered to the local fire prevention bureau.
After submission, the fire authority reviews the report. If everything checks out, you receive a confirmation that the property is in compliance. If the report shows a deficiency, expect a follow-up inspection requirement with a deadline for repairs. Keep the confirmation receipt with your records.
Keep the Form on File
Under the International Fire Code, inspection, testing, and maintenance records must be retained for at least three years on the premises or at another approved location, available to the fire code official on request.7National Fire Sprinkler Association. The Paper Trail – Documentation and Owner Retention from Codes to NFPA 25 NFPA 25 adds a separate rule: keep each record for one year after the next inspection of the same type. So a 2025 annual visual inspection form stays on file until the 2026 annual visual is complete. Acceptance records and initial installation records must be retained for the life of the system.
Three years is the safe minimum in most jurisdictions, but holding records through at least the next five-year fire service main flow test gives a more complete paper trail. Insurance auditors routinely ask for several years of documentation when reviewing coverage, and a gap can be treated the same as a missed inspection.
