What to know about plumbing in Anaheim
Anaheim began in 1857 as a colony of German farmers and winemakers, and the name joins Ana, for the Santa Ana River, with heim, the German word for home. George Hansen surveyed the first 200 acres, today's downtown, between North, South, East and West streets, and a willow fence ringed them. The town incorporated in 1876 with 881 residents. When disease killed the vines, its growers turned to citrus and raised the first commercially successful oranges in Orange County, and the Anaheim Cemetery, opened in 1866, was the county's first public cemetery. The big growth came much later: 20 square miles were annexed from 1949 to 1959, and the 5 reached town in 1954. Inside the city limits today are the Disneyland Resort and the Convention Center, Angel Stadium, Honda Center, ARTIC and the Mother Colony House, and the 5, 91, 57, 55, 22 and 241 all cross it. Fullerton, Placentia and Yorba Linda lie to the north, Orange, Garden Grove and Stanton to the south, Buena Park and Cypress to the west, and the eastern hills follow the Santa Ana River out to the county line.
According to the ACS 2020-2024 5-year estimates, the median Anaheim home was built in 1973. Sixty-five percent of the housing predates 1980, 22 percent comes from the 1950s and 23 percent from the 1970s, and just 41 percent is single-family detached. The neighborhoods show those layers one by one. The Anaheim Colony Historic District, designated in 1997, keeps early-1900s Craftsman, bungalow, Tudor, Spanish and Colonial Revival houses, with Five Points and the Historic Palm District next to it, while in the Hoskins Historic District the groves were cleared about 1946 and the houses followed. West Anaheim along Beach Boulevard filled in mostly during the 1960s and 1970s. Anaheim Hills was planned from 1970, and Westridge, its first neighborhood, opened in July 1972. In the Platinum Triangle, high-density housing is going up where industrial buildings stood. Older houses in the colony streets and the postwar tracts often still carry their original supply pipe and cast iron drains, and the apartments and condos add shared walls and shared stacks to the list.
Water has been a city service here since 1879. Anaheim Public Utilities runs 758 miles of mains and 64,696 meters, holds water in the 920-million-gallon Walnut Canyon Reservoir and filters it at the Lenain plant, the only city-owned filtration plant in Orange County. Anaheim is one of three cities in the county that buy imported water directly from the Metropolitan Water District instead of through the county wholesaler. In 2025 purified local groundwater reached more than 80 percent of customers through nine groundwater treatment plants, and the Orange County Water District sends purified water to recharge basins in Anaheim to help refill the basin. That groundwater is very hard, about 18 grains per gallon in 2025, with Lenain water near 17 and imported water near 14. At that level scale settles in the bottom of a tank heater, crusts aerators and shower heads, and wears out faucet cartridges and fill valves. The City system has no lead service lines. About 10,000 backflow assemblies in town must be tested every year by a tester certified by the Orange County Health Care Agency. The same utility sells electricity too, the only municipal electric utility in Orange County, started by Anaheim voters in 1894.
Anaheim counts the whole sewer lateral as private property: from the house to the main, the stretch beneath the street included, the owner keeps it up. The City's guide says most laterals are 4- to 6-inch clay pipe with a typical life of 30 to 50 years, and it asks plumbers to pull a permit before any significant repair. The Public Works Sewer and Storm Drain Maintenance Division looks after the City lines, and the Orange County Sanitation District treats what flows through them. Permits come from the City of Anaheim Building Division, part of the Planning and Building Department at City Hall, 200 S. Anaheim Blvd. Each one closes only after inspection, which means a water heater strapped twice against earthquakes with its relief valve piped somewhere safe, and gas piping that holds a pressure test. On our map, the closest location to Anaheim is Orange, with Fullerton second, and the finished work carries our written workmanship warranty.
Anaheim borders Fullerton, Placentia, Yorba Linda, Orange, Garden Grove, Stanton, Buena Park and Cypress. We take calls from each of those as well, and the plumber for any of them comes from our location nearest that address. Someone picks up the phone around the clock, the plumber hunts down the true starting point of a leak or clog before a wall or floor gets cut, and the work waits for your signature on the written estimate.
