Lake Forest (originally known as El Toro) incorporated in 1991 and encompasses a wide range of housing from the 1970s through 2000s. The city grew from the original Saddleback Valley developments of the 1970s, expanded through the 1980s and 1990s, and added newer communities like Baker Ranch and Portola Hills in the 2000s.
The oldest Lake Forest homes are now 50+ years old with copper supply lines and cast iron drain systems showing their age. Even the 1990s homes are reaching the point where water heaters, angle stops, and fixtures need replacement. We handle plumbing for Lake Forest homes of every era.

Lake Forest Hard Water and Your Plumbing
Lake Forest receives water from the El Toro Water District and Trabuco Canyon Water District with typical hardness of 12 to 20 GPG. Over decades, this causes scale buildup in pipes, water heaters, and fixtures.
A water softener is a smart investment, especially for the older neighborhoods. Learn more about water treatment.
