Local notes for Mission Viejo

Most of Mission Viejo was planned and built by a single developer, starting in the late 1960s, and the city incorporated in 1988. The land under it is hilly, so streets were graded into terraces and slopes, one row of tile roofs stepping above the next. On hillside lots the pressure arriving from the street can run high. A pressure regulator near the main shutoff holds it down, and on these streets regulators work hard and wear out. Pipes that knock when a valve closes, a toilet that refills by itself or a relief valve dripping at the water heater are the usual early signs.

The US Census counts about 34,300 homes in the city. The median one was built in 1979, 52 percent are older than 1980, and 71 percent are single-family detached houses. The typical home is a tract house from the late 1960s through the 1980s, poured on a concrete slab with copper water lines under the floor. Years of hard imported water wear that copper thin until it opens a pinhole, and since the pipe sits under concrete, the first clue is often a warm spot on a tile floor, running water you can hear with every faucet off, or a bill that keeps rising. Newer sections of the city went in with PEX water lines and tankless heaters, which bring a shorter list of repairs of their own.

Because we are based here, a call from anywhere in Mission Viejo is answered by a person and handled from our Mission Viejo location, the nearest of our 10 in Orange County. There is nothing to drive to: the plumber comes to you. That means the homes around Lake Mission Viejo, Painted Trails and Stoneridge, the streets off Marguerite Parkway and Crown Valley Parkway near Saddleback College and The Shops at Mission Viejo, the blocks along the Oso Creek Trail by the 5 freeway, and the east side up toward the 241 toll road.

Water and sewer service comes from the Santa Margarita Water District or the Moulton Niguel Water District, depending on the street, and gas comes from SoCalGas. The district owns the public sewer main; the private lateral from your house to that main belongs to you. Decades-old laterals take in roots from mature trees, and on a slope the soil can move just enough to open a joint, so the line gets a camera inspection before any repair is proposed. The City of Mission Viejo issues the permits for this kind of work, from a sewer lateral or a repipe to a gas line or a new water heater, and each one we pull is closed after the inspection passes.

Mission Viejo shares borders with Lake Forest, Rancho Santa Margarita, Laguna Hills, Laguna Niguel, Ladera Ranch and San Juan Capistrano. We work in each of those places as well, and the plumber is sent from whichever of our locations sits closest to your address. A person answers at any hour, the line is inspected before anything gets opened up, and you see the price in writing before work starts.

What brings us out in Mission Viejo

  • 01Slab leaks and pinhole leaks in the copper under tract homes from the late 1960s to the 1980s, traced to the spot before a single tile is lifted.
  • 02Worn pressure regulators on terraced and hillside streets, where high street pressure leaves pipes knocking and toilets refilling on their own.
  • 03Tank and tankless water heaters choked with scale from the hard water South County imports, replaced under a City of Mission Viejo permit, braced with a pair of seismic straps and given a relief valve line that ends somewhere safe.
  • 04Sewer laterals under older lots, blocked by roots from mature trees or pulled apart at a joint where the slope has shifted.

Homes by the numbers

The age and shape of Mission Viejo housing

  • 1979Median build year
  • 52%Share from before 1980
  • 71%Single-family share
  • 34,285Total homes

Roughly 52 percent of Mission Viejo homes date from before 1980 and the rest came later, so the housing splits close to down the middle. Older houses were typically built with copper or galvanized water lines and cast iron or clay drains; later ones moved to copper, PEX and plastic drain pipe. Because two neighbors on one street can have different pipe, a problem that keeps returning gets looked at closely before anyone writes up a repair.

Detached single-family houses make up 71 percent of Mission Viejo homes, so most addresses here have a sewer lateral of their own, running from the house to the public main and maintained by the owner.

Common questions

Mission Viejo plumbing questions

Is my water from the Santa Margarita or the Moulton Niguel Water District?
It depends on the street. Both districts serve parts of Mission Viejo, and your water bill names the one that serves you. For plumbing it changes little: either way the district owns the public main, and the private sewer lateral from your house to that main is yours to maintain.
Does a new water heater in Mission Viejo need a city permit?
Yes. The City of Mission Viejo permits water heater replacements, along with repipes, sewer laterals and gas lines. The new heater is held by two seismic straps, and its temperature and pressure relief valve drains to a safe place. The permit is pulled before work begins and closed once the inspector signs off.
Why is the water pressure so high in my hillside house?
Many Mission Viejo streets were graded into terraces, and on hillside lots the pressure coming in from the street can run high. A pressure regulator at the main brings it down to a level your fixtures can handle, but regulators wear out. If pipes knock or toilets keep running, we can test the pressure and give you a written quote before anything is replaced.
