Moving ground and leaking hydrants
Cal Water, which supplies Rancho Palos Verdes through its Palos Verdes System, has reported more water main leaks in the city caused by ground movement. Private pipe is buried too. A private fire service main and its hydrant sit in the same soil, and in parts of the city where the ground shifts (it matters most near the Greater Portuguese Bend Landslide Complex), joints can open and a hydrant can start to lean. Watch for these signs:
- Wet ground or pooling near the hydrant on a dry day.
- A hydrant that leans or sits lower than it used to.
- Water at the outlets or bonnet with the valve shut.
- An operating nut that won't turn, or spins without opening anything.
A leak on the main also cuts the water the fire department gets when it opens the hydrant. A flow test will catch it. A fire is a bad time to find out.
Is the hydrant yours to repair?
Usually, a hydrant on the public main is the water company's. Report those to Cal Water. A hydrant on your side of the connection, fed by a private fire service main, is the property owner's to keep working, and that's the hydrant we repair. Not sure which you have? Your site plans will usually show where the private main begins.
What a repair visit covers
First we find out why it failed. The technician closes the control valve, operates the hydrant, and checks the barrel, drain, outlets and caps for leaks or damage. Typical repairs include:
- Replacing worn seats, gaskets and drain valve parts.
- Freeing or replacing a seized operating nut or stem.
- Replacing damaged caps, outlet nozzles or stripped threads.
- Resetting or replacing a hydrant knocked over by a vehicle.
- Fixing a leaking section of the private fire service main.
Once the parts are in, the hydrant is flushed and put back in service.
LA County Fire and the code
The city has no fire department. Rancho Palos Verdes contracts with the Los Angeles County Fire Department (LACoFD), and its Battalion 14 provides fire suppression and fire prevention services here. The city's fire code is based on the 2025 California Fire Code, in effect since January 1, 2026, along with the Los Angeles County Fire Code and local amendments. NFPA 25 covers the upkeep and repair of private hydrants, and it calls for each one to be flow tested and inspected every year (see our annual fire hydrant testing in Rancho Palos Verdes). Got a write-up? Ask LA County Fire what they need to see before they close it out.
Who does the work
California work for 1 Pro Fire is done by Hedrick Fire Protection. It holds C-16 fire protection and C-10 electrical contractor licenses, and the California State Fire Marshal licenses it under Title 19 for inspection, testing and maintenance of water-based fire protection systems, which includes private hydrants. Rancho Palos Verdes (90275) is in our service area. Call (213) 568-0188 or email socal@1profire.com with the address and what's wrong.

Rancho Palos Verdes hydrant repair questions
Is fire flow testing available in Rancho Palos Verdes?
Yes. One request we've had was for a test the fire department needed on an empty new-construction lot, where the owner thought an earlier hydrant reading had been wrong.
What do the bonnet colors mean?
Under NFPA 291, the bonnet color shows the hydrant's flow class. It should match what a flow test measures.
Does the hydrant stay in service during a repair?
Usually not. It's shut off at its control valve while the work is done, so ask LA County Fire whether they want notice before it goes out of service.
Can a hydrant hit by a car be fixed?
Often, yes. The technician checks the barrel, valve and main for damage below the break before replacing parts.
