Plumbing in Walnut & Los Angeles County
Many Walnut homes were built in the post-war decades with galvanized or early copper piping that is now reaching the end of its service life.
Mature trees along Walnut streets send roots into older clay sewer laterals, a leading cause of main line backups here. Coastal air and salt can speed up corrosion on exposed pipes, hose bibs and water heater fittings in parts of Los Angeles County.
