Aliso Viejo is one of Orange County's newer cities, developed by the Mission Viejo Company starting in 1982 on 6,600 acres of the former Moulton Ranch. Nearly all of Aliso Viejo's housing was built between 1982 and the early 2000s, giving the city a cohesive, relatively modern feel. But "modern" is relative. The earliest homes are now 40+ years old, and even the newer ones are approaching 25 years.
At this age, copper supply lines are developing their first pinhole leaks from hard water exposure. Original water heaters have been replaced once already, and the replacements are now failing. ABS drain connections are loosening. Angle stops and supply valves that haven't been touched in decades are corroding shut. These are the issues we see daily in Aliso Viejo, and we know exactly how to address them.
HOA plumbing note: Many Aliso Viejo neighborhoods are governed by HOAs with specific requirements for plumbing work, including approval processes and contractor insurance requirements. We carry the licensing and insurance that HOAs require and coordinate with your association as needed.
Aliso Viejo Neighborhoods We Know Inside and Out
Aliso Viejo was developed in phases over two decades. Here is what we typically find in each era of construction.
Westridge / Silver Oaks / Skyview
1982 to 1990
The earliest Aliso Viejo neighborhoods, built during the initial development phase. These homes are 35 to 40+ years old with copper supply lines and ABS drain systems. At this age, copper pinhole leaks, water heater failures, and corroding angle stops are the most common issues. These homes are entering the window where repiping becomes a serious consideration.
Wood Canyon / Glenwood / Highlands
1988 to 1995
Mid-phase development with a mix of single-family homes, townhomes, and condos. Copper supply with ABS drain. At 30 to 37 years old, these homes are seeing their second round of water heater replacements and increasing fixture failures. Supply valve corrosion from hard water is becoming noticeable.
Pacific Ridge / Audubon / Seascape
1990 to 2000
Later-phase development including gated communities and hillside homes. Plumbing systems are in better overall condition at 25 to 35 years old, but water heaters, angle stops, and hose bibs are reaching end of life. Homes on hillsides may have longer sewer laterals that need periodic camera inspection.
Town Center Area / Vista Heights
1995 to 2005
The newest residential areas, many built around the Aliso Viejo Town Center. These homes are 20 to 30 years old with plumbing in generally good condition. Common issues are water heater replacement, fixture upgrades, and gas line additions for outdoor living features.
Condos and Townhomes (Various)
1982 to 2000
Aliso Viejo has a significant number of condos and townhomes throughout the community. Plumbing in multi-unit buildings presents unique challenges including shared walls, limited access, and HOA coordination requirements. We handle condo and townhome plumbing regularly and understand the constraints.
Aliso Viejo Hard Water and Your Plumbing
Aliso Viejo receives water from the Moulton Niguel Water District, which imports water from the Metropolitan Water District. The water is typically 12 to 18 grains per gallon (GPG) hardness. While not as extreme as some north OC cities, this level of hardness still causes meaningful scale buildup in water heaters, pipes, and fixtures over 25 to 40 years.
A water softener protects your entire plumbing system from ongoing scale damage and extends the life of your water heater and appliances. At 12 to 18 GPG, a water softener is a smart investment for any Aliso Viejo homeowner. Learn more about water treatment.
