Plumbing service throughout Brea

Brea has two kinds of housing, and each has its own plumbing problems.

Downtown and the older central tracts have homes from the oil-boom years through the 1970s. Many still have galvanized steel supply lines and cast iron drains, which show up as low pressure, discolored water, and slow drains.

The hillside communities, Olinda Ranch, Blackstone, La Floresta, and the homes near Carbon Canyon, are newer. There the calls are for slab leaks and for wear caused by the higher water pressure on elevated lots, which also speeds up scale in supply lines and water heaters.

What Brea homeowners should know

Your home's pipes, by the year it was built

  • Built before 1960Galvanized steel supply and cast iron drains, downtown, in Central Brea, and in Eagle Hills. Both are past their service life.
  • 1960s to 1980sCopper supply with cast iron drains on slabs, mainly in Central Brea. Hard water causes pinhole leaks, and slab leaks become more likely with age.
  • 1990s to todayCopper or PEX supply with ABS or PVC drains, in the hillside communities. Higher pressure speeds up scale.

Water hardness

Brea's water is hard to very hard, commonly 12 to 18 grains per gallon according to City of Brea Water Division and Cal Domestic Water Company reports. Regular water heater flushing helps, and a softener is worth considering on older copper or galvanized lines.

Permits

In Brea, jobs like water heater replacement, sewer repair, gas line work, and whole-home repiping generally require a city permit and inspection. We tell you at the estimate when one applies. Unpermitted work can cause problems when you sell the house or file an insurance claim.

Plumbing questions from Brea

How quickly can you get to a home in Brea?

Brea is next door to our Fullerton office. We give you an honest arrival window when you call, and emergencies are sent out first.

What kind of pipes are in older Brea homes?

Homes from the oil-boom years through the 1970s often have galvanized supply lines and cast iron drains. Galvanized rusts inside and lowers pressure; cast iron corrodes and slows drainage. A camera inspection or pressure test tells us what you have before a repair is chosen.

Do plumbing jobs in Brea need a permit?

Water heater replacements, sewer repairs, gas line work, and repipes generally do.

How hard is the water in Brea?

Commonly 12 to 18 grains per gallon, per the city's water reports. Scale shortens the life of water heaters and fixtures. Regular flushing helps.

What customers say

★★★★★

Great experience with Miguel and Steven! Fixed my stubborn kitchen sink clog. Very informative and respectful of my home in addressing the issue. Highly recommend!

I had an excellent experience with SoCal 1 Plumbing! Eliass came out to clear a blockage in my kitchen line by snaking it through the outside wall clean-out, and everything was done efficiently and with great care. He also installed new tubular drains under my kitchen sink to stop the leaks I’d been dealing with. The work was high-quality, and they even provided a 1-year warranty on parts and labor, which gave me peace of mind. Highly recommend their professional and reliable service!

I had a plumbing issue that needed to be repaired sooner than later. Miguel came out and knew how to fix it immediately. Miguel was professional, friendly and knowledgeable. I won't hesitate to call them in the future.
