Why do Aliso Viejo tankless heaters need descaling?

South Orange County's imported water is hard, and heating it leaves mineral scale inside the heat exchanger of a tankless unit. Over time that cuts hot water flow and makes the temperature swing. Descaling clears it out, and the work is quoted in writing before it begins.

My townhome shares a wall with a neighbor. Whose leak is it?

It depends on where the leak starts. We find the source first, so you know whether it is in your unit's line, your neighbor's, or a pipe your HOA maintains, and the written estimate goes to whoever owns the repair.

Do you cover the whole of Aliso Viejo?

Local notes for Aliso Viejo

Help for Aliso Viejo comes from our Laguna Niguel location, the nearest of our 10 in Orange County, and our Mission Viejo location is the next closest. The city borders Laguna Woods, Laguna Hills, Laguna Niguel and Laguna Beach, with Aliso and Wood Canyons Wilderness Park right beside it, and we cover every street in ZIP 92656.

Aliso Viejo was planned in the 1980s and 1990s and became a city in 2001. The Census counts about 20,500 homes, with a median build year of 1995 and only 6 percent built before 1980. Just 36 percent are single-family detached; most people here live in condos and townhomes.

Homes of that age were plumbed mostly with PEX or copper, and the pipe itself is rarely what fails. The equipment is. Tankless water heaters need descaling because South Orange County's water is hard, and the recirculation pumps that keep hot water close to the tap wear out. Both are common calls in Aliso Viejo.

In a townhome or condo, plumbing is shared in ways a house's is not. A drain line may also serve the unit next door, and a leak can cross a party wall before anyone sees it, so the first step is finding whose pipe it is. Permits for water heaters, repipes and gas lines come from the City of Aliso Viejo, and we close them after the city's inspection.

Aliso Viejo shares borders with Laguna Woods, Laguna Hills, Laguna Niguel and Laguna Beach. 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.

Homes by the numbers

The age and shape of Aliso Viejo housing

1995Median build year
6%Share from before 1980
36%Single-family share
20,507Total homes

Only 6 percent of Aliso Viejo homes predate 1980, and most of the rest were built in the 1990s or later with PEX or copper water lines. In homes this young the pipe is rarely the trouble. The calls are about tankless heaters scaled by hard water, recirculation pumps that stop, pressure regulators that drift, and the occasional slab leak.

Just 36 percent of Aliso Viejo homes are detached single-family houses. Most people live in condos, townhomes or apartments that share drain stacks and laterals, so the pipe behind a backup may belong to the association rather than the unit, and the repair gets planned with the HOA.
