About 44 percent of Highland homes were built before 1980, so many still have original supply lines that are wearing thin. A plumber can replace those lines with PEX or copper, either a section at a time or for the whole house. Call the number on this page to be connected with a local plumber in Highland.
Highland conditions
Highland sits at the southern base of the San Bernardino Mountains and grew from citrus groves and the railroads. Census figures reported by Point2Homes put the median year built at 1983, with the 1980s and 1990s as the busiest building decades and about 43.8 percent of homes older than 1980. Houses near the Palm Avenue historic district and other older areas are the likeliest to have galvanized steel or early copper; homes from the 1980s and 1990s more often need targeted repairs.
The City of Highland's plan-check handout names East Valley Water District as the water agency, and new construction must connect to sewer where available, subject to EVWD review. Not every address has been verified as EVWD, so check your bill. The City of Highland Building & Safety Division requires permits for plumbing systems.
Before recommending a full repipe, a good plumber checks exposed pipe, looks at past repairs and may cut a short sample from an older line to see how much corrosion or scale is inside. That evidence tells you whether the pipe has years left or is close to failing everywhere at once.
Routing the new lines
| Route | Where it fits | Trade-offs |
|---|---|---|
| Attic, down interior walls | Most slab homes | Small wall cuts; lines need insulation from heat and cold |
| Crawl space | Raised-foundation homes | Fewer wall openings; access can be tight |
| Under the slab | Rarely chosen | Breaking concrete and floors; hard to service later |
| Partial reroute | One failing branch, such as a hot line under the floor | Leaves other old pipe in service |
Signs to look for
- Repeated leaks or a slab leak on original pipe
- Rust-colored water after the house sits
- Gradual pressure loss throughout the home
- Crusty buildup at joints and valves
- Exposed pipe that is corroded or patched in several spots
Seasonal notes
Highland's position against the mountains means colder nights than much of the valley floor in winter, so lines in attics, garages and exterior walls should be insulated. In summer, attic work is slow, which is one reason many owners plan a repipe for spring or fall. Permit questions go to Building & Safety at 27215 Base Line, (909) 864-8732 ext. 232; the plumber usually files the application and schedules the inspection.
