A new hydrant starts with an approved plan
Adding a private hydrant to a Placentia property is a permitted job. Plan for that. Since March 20, 2023, the Placentia Fire and Life Safety Department has handled all fire-related plan checks and permits in the city, so drawings for your hydrant and its supply line are emailed to FireCRR@placentia.org, and review begins once the plan check fee is paid. If your drawings name the Orange County Fire Authority, update them before you submit.
The design follows NFPA 24, the standard for private fire service mains and the hydrants and valves on them. In November 2025 the city adopted the 2025 California Fire Code, with local amendments, as the Placentia Fire Code. Plans should meet both.
Find your water company before anyone digs
A private hydrant draws from the public water system, so the water company for your address usually has its own requirements for the connection. Golden State Water Company supplies Placentia. The Yorba Linda Water District serves about one-third of the city. Check your water bill. The company named on it is the one you work with on the connection and the hydrant flow test.
How a Placentia hydrant installation runs
- Plans and permit. Drawings go to the Placentia Fire and Life Safety Department for plan check. Work starts after approval.
- Water company requirements. Ask Golden State Water or the Yorba Linda Water District what it needs for the connection and whether it wants to be on site.
- Installation. We set the hydrant, install its isolation valve and connect it to the fire service main.
- Flush and pressure test. The new main and hydrant are flushed and pressure tested. Then come the sign-offs.
- Fire inspection. The department's plan review application lists (714) 993-8135 for scheduling fire inspections. Keep the permit and approved plans on site. Without them, the inspection is cancelled.
- Water company close-out and flow test. Before the hydrant goes into service, close out the connection with the water company for your area, including the flow test that records how much water the new hydrant can deliver.
Once it's in service
NFPA 25 calls for private fire hydrants to be inspected and flow tested every year. Book the first one now. Our annual fire hydrant testing in Placentia page covers that visit, and if a hydrant later leaks, sticks or gets hit by a vehicle, see fire hydrant repair or fire hydrant maintenance.
