Annual Fire Hydrant Testing in Downey

New code, same yearly test

In January 2026, Downey adopted the 2025 California Fire Code with its own local amendments. The two ordinances replaced the city's fire hydrant provisions, plus its fire code, hazardous materials and fireworks sections. Sounds like a big change. It mostly isn't. Downey's Fire Marshal called the amendments mainly organizational, with no real policy changes proposed.

Your test schedule stays the same. Under NFPA 25, the trade standard for water-based fire protection, every private fire hydrant gets inspected and flow tested once a year.

Who checks? Business fire and life safety inspections in Downey are done by the Downey Fire Department's Fire Prevention Division. The city's Fire Prevention web page still cites an older code edition, so if you need to know which local section applies to your site, call the division and ask; don't go by the page.

Is this hydrant on your test list?

Start with the pipe. If a hydrant is fed by your private fire service main (the underground line that carries firefighting water across your property, covered by NFPA 24), it's yours to maintain and test every year. The City of Downey runs its own water utility through Public Works. Questions about a hydrant on the public system go to the city.

What happens at the annual test

A typical visit goes like this:

• A visual check of the barrel, caps, outlets and threads for damage, leaks or missing parts.
• Opening the hydrant fully and flowing water.
• Taking flow readings using NFPA 291 methods. That standard also sets the bonnet color code that tells engine crews a hydrant's flow class at a glance.
• Closing it and watching the seat and caps for leaks.

Keep the results with your other fire protection records. An inspector may ask for them.

If the test turns up a problem

Some hydrants fail. One Downey caller's hydrant started leaking after a crew shut it off following water use, and they suspected a broken seal. A yearly test can catch that kind of fault while it's still a small fix, before a fire crew finds it the hard way during a hookup. Repairs are handled through our Downey fire hydrant repair service, and routine upkeep between tests is covered under fire hydrant maintenance.

Who does the work

In California, 1 Pro Fire work is performed by Hedrick Fire Protection, which holds C-16 (fire protection) and C-10 (electrical) contractor licenses and is licensed by the California State Fire Marshal under Title 19 for inspection, testing and maintenance of water-based fire protection systems.

Most of the calls we get from Downey are about extinguishers. Hydrants come next. To book a hydrant test anywhere in Downey (ZIP codes 90239 through 90242), call (213) 568-0188 or email socal@1profire.com

Downey hydrant testing questions

The hydrant connection is on our property. Is it ours, or part of the city's sidewalk hydrant?

If it's fed by your private fire service main, it's yours. For a hydrant on the public water system, ask the City of Downey's Utilities Division.

How often does a private hydrant need testing?

Once a year. NFPA 25 calls for an annual inspection and flow test on each private hydrant.

Did the 2026 code change hydrant testing in Downey?

Probably not. The city's Fire Marshal described the January 2026 amendments as mainly organizational, but confirm the details for your site with the Fire Prevention Division.

Can I get a repair estimate on a leaking hydrant without a visit?

No. A recent Downey quote was $250 to send a technician to inspect a leaking hydrant and estimate the repair, and we don't give free estimates for that work.
