About plumbing in Lake Forest
Portola Hills is the part of Lake Forest that meets Rancho Santa Margarita, and it shares a water district with several neighborhoods across that line: like Dove Canyon, Robinson Ranch and Trabuco Highlands, it gets its water from the Trabuco Canyon Water District. Portola Hills and Foothill Ranch are among the newer parts of the city, plumbed with PEX and fitted with tankless water heaters. Hard imported water builds scale inside those heaters, and that is behind many of the calls from these streets: error codes, and water that swings between hot and lukewarm.
Closer to El Toro Road the houses are older. Much of the area was long known as El Toro, until the city incorporated as Lake Forest in 1991. Copper in those early tracts has been in service a long time, and a house that has already had a pinhole leak or two is a candidate for a repipe in copper or PEX. Mature trees on the older lots also send roots into sewer laterals, and the lateral belongs to the homeowner from the house to the public main.
By the Census count Lake Forest holds about 31,800 housing units, more than any other place with a page on this site. The median home dates from 1984, 38 percent date from before 1980, and single-family detached houses make up 53 percent. The other 47 percent are condos, townhomes and apartments, where walls and drain stacks are shared, a leak may start in the unit next door, and repairs on a common line are coordinated with the HOA.
Among our 10 Orange County locations, the one in Mission Viejo is nearest to Lake Forest, and Rancho Santa Margarita is second. The City of Lake Forest permits repipes, gas lines, sewer laterals and new water heaters. A replacement heater is anchored by a pair of earthquake straps, its relief valve gets a drain line to a safe spot, gas lines are pressure tested, and the city inspects before the permit closes.
Lake Forest is bordered by Mission Viejo, Irvine, Laguna Hills and Rancho Santa Margarita. Those places are on our list too, and a call from any of them goes to our location closest to the address. A real person answers the phone at any hour, the cause is pinned down before a wall or floor gets opened, and you approve a written estimate before the plumber begins.
