Placentia Water: Two Water Companies, Hard Water and Home Filtration
Who supplies your water?
Placentia is split between two water providers.
- Golden State Water Company serves most of the city through its Placentia Yorba Linda system — a blend of local groundwater and imported water.
- Yorba Linda Water District serves about one third of Placentia. Its office is right here in Placentia on Miraloma Avenue.
Your water bill tells you which one you have. Call them about the meter or anything on the street side of it. Everything on your side — from the service line to the faucets — is yours to repair.
Is Placentia water hard?
Yes. Golden State Water's 2025 report shows an average hardness of 11.0 grains per gallon, ranging from about 4 to 17.5. Anything over 7 counts as hard.
- White crust on faucets and showerheads
- Spots on dishes and glass
- Scale building up in water heaters
- Tankless units that need regular descaling
Water quality note: PFAS and filtration
In 2020, Golden State Water took two Placentia wells — Bradford Wells 3 and 4 — out of service after tests found PFOA above state levels. The company says the water it delivers meets all quality and safety standards.
Some homeowners still want extra filtering at the kitchen tap. A 2020 Duke University study of home filters found that under-sink reverse osmosis and two-stage filters removed nearly all PFAS. Whole house systems varied widely.
A water softener treats hardness. It isn't designed to remove PFAS. For PFAS reduction, an under-sink reverse osmosis system is the most proven option.

Plumbing in Older Placentia Homes: Old Town, Atwood and Midcentury Tracts
Placentia became a city in 1926. It grew around orange groves, oil wells that started pumping in 1919, and the Santa Fe Railroad stop. Atwood was built as a community for oil workers. Today, about 35% of Placentia homes were built before 1970, and some Old Town homes go back to the 1920s. About half the city was built between 1970 and 1999.
| Area and era | Pipes you'll often find | What usually goes wrong |
|---|---|---|
| Old Town, 1920s to 1940s | Galvanized water lines, cast iron drains, clay sewer pipe, older gas lines | Rusty water, low pressure, roots in the sewer, worn valves |
| Atwood and midcentury tracts, 1940s to 1960s | Galvanized or early copper, cast iron drains, clay or Orangeburg sewer pipe | Rusty water, slow drains, sewer backups |
| 1970s to 1990s tracts | Copper under a slab, plastic or cast iron drains | Slab leaks, pinhole leaks, water heater wear |
| 2000 and newer | Copper or PEX, plastic drains | Fixtures, water heaters, hard water scale |
Every home is different and many older homes have been partly updated. A quick inspection tells you what you actually have.
Buying an older home in Placentia? Before you close, get a camera inspection of the sewer line and have someone look at the water pipes. Plumbing surprises after the sale are some of the most expensive ones. See repiping and sewer line repair.
Leak Detection and Slab Leak Repair in Placentia, CA
"My water bill was like $507 all of a sudden last month." About half of Placentia homes were built between 1970 and 1999, most with copper water lines under a concrete slab. Those pipes are now 25 to 55 years old, and pinhole leaks are common. We find leaks with listening tools and thermal cameras, then open only the spot that needs fixing.
Quick leak check: Turn off every tap, the washer, the dishwasher and the sprinklers. Watch your water meter for 15 minutes. If it moves, you have a leak.

Galvanized Pipe Replacement and Whole House Repiping in Placentia
Rusty water first thing in the morning and weak showers in Old Town and Atwood usually mean galvanized pipe that's closing up inside. In 1970s to 1990s homes, pinhole leaks that keep coming back mean the copper is wearing thin.
Repair or repipe?
Repair: one leak in pipe that's otherwise sound.
Repipe: rusty water, weak pressure all over the house, or two or more leaks in a year.

Sewer Line Repair, Camera Inspection and Root Removal in Placentia
"Some sewage is backing up into our shower." Older Placentia neighborhoods have older sewer lines. Clay pipe lets roots in at the joints. Orangeburg pipe — made of pressed tar paper — can flatten with age. Decades of mature trees make both problems worse.
Signs the main line is the problem
- More than one drain is slow
- Toilets gurgle when the sink runs
- Water rises in the tub when you flush

Drain Cleaning and Hydro Jetting in Placentia, CA
In older Placentia homes, cast iron drains build up scale on the inside so the opening keeps shrinking. In newer homes, most clogs are grease or hair. We check the drain before we choose the tool.

Water Heater Repair, Replacement and Tankless Installs in Placentia
"We have a water heater leak in our garage." Hard water in much of Placentia averages about 11 grains per gallon. That leaves sediment in tank water heaters and scale inside tankless units, which shortens their life.
Repair or replace?
Repair: under 8 years old with one failed part.
Replace: over 10 years old, or leaking from the tank itself.

Faucet, Shower Valve and Shutoff Valve Repair in Placentia
Older Placentia homes often still have their original shutoff valves. When they haven't been turned in years, they stick or break off in an emergency. We swap them for quarter-turn valves that shut off fast.

Placentia, CA Plumbing Questions, Answered
Two companies serve Placentia. Golden State Water Company covers most of the city, and Yorba Linda Water District covers about one third. Your water bill shows which one you have. Call them about the meter. Everything on your side of the meter is yours to repair.
Yes. Golden State Water's 2025 report shows an average hardness of 11.0 grains per gallon in the system serving Placentia. Anything over 7 counts as hard. A water softener helps protect your water heater, fixtures and pipes.
Golden State Water took two Placentia wells out of service in 2020 after tests found PFOA above state levels. The company says the water it delivers meets all quality and safety standards. If you want extra filtering at the tap, an under-sink reverse osmosis system is the most proven option.
A 2020 Duke University study found that under-sink reverse osmosis and two-stage filters removed nearly all PFAS. Pitcher and faucet filters were less consistent, and whole house systems varied widely. An under-sink system at the kitchen tap is the most proven option.
No. A water softener removes the minerals that make water hard, like calcium and magnesium. It isn't designed to remove PFAS. For that, an under-sink reverse osmosis or two-stage filter is the better choice.
Look at the pipes near your water heater or where the main enters the house. Galvanized pipe is dull gray steel with threaded joints. Rusty water, weak pressure and leaks at the joints are common signs. A plumber can confirm it in a few minutes.
Not always, but find out first. Get a sewer camera inspection and have the water pipes checked before you close. If the home still has galvanized pipe or a damaged sewer line, you'll know the real cost before the sale is final.
Look for warm spots on the floor, damp carpet with no clear cause, the sound of running water when nothing is on, or a water bill that jumps. About half of Placentia homes have copper lines under the slab, so these signs deserve a quick call.
California landlords must keep plumbing in good working order, so most repairs are the owner's job. Tenants can be charged when they cause the problem, like a blocked drain from something flushed. Check your lease for the details.
It depends on the size of the home, the number of bathrooms, the pipe you choose and how easy the walls are to reach. We look at your home first and give you upfront pricing before any work begins.
Yes. Our line is answered 24/7 and most Placentia calls get a plumber the same day. Burst pipes, floods and sewage backups are handled first, including nights and weekends. Call (949) 804-1047 any time.
Yes. Repiping and water heater replacement need a permit and an inspection through the City of Placentia's building division. Permitted work keeps your home safe and helps when you sell.
