Repiping in Rialto, CA

Which water company serves my Rialto home?

That depends on the address. Rialto has three water retailers: the City of Rialto through Rialto Water Services, West Valley Water District and Fontana Water Company. The city's own system relies primarily on local groundwater. Your water bill shows which one serves you. It matters for a repipe mainly when the job includes the buried line from the meter to the house, since each provider sets its own rules about where its equipment ends and yours begins. A plumber should confirm with the right provider before digging near the meter.

How do I know my pipes need replacing, not just repairing?

Look for a pattern. One leak on pipe that otherwise looks clean is a repair. The signs that point toward a repipe are different:

• Leaks showing up in different rooms within a year or two
• Rust-colored water when a tap first opens, common with galvanized steel
• Low pressure at every fixture rather than at one faucet
• More than one slab leak on the original lines
• Pipe that is already patched in several spots

A plumber can often confirm the condition by looking at exposed pipe near the water heater and under sinks, or by cutting a short sample from an older line. Galvanized steel that has narrowed from rust inside cannot be cleaned back to full flow; replacing it is the only lasting fix.

What permit does a repipe need?

Plumbing work in Rialto goes through the City of Rialto Community Development, Building & Safety Division at 150 S. Palm Avenue, 909-820-2505. Permits can be filed online through the city's Tyler EnerGov portal. The plumber usually applies and schedules the inspection, so ask that it be included in the quote.

A local note

Most Rialto houses sit on slabs, so a plumber typically runs new lines through the attic and down interior walls and caps the old under-slab pipe. Attic work in July and August is slow, so if your situation is not urgent, fall through spring is an easier time to schedule it. Ask the plumber to insulate new lines in the attic and garage; it keeps hot water hotter on the way to the tap and protects against the occasional frosty winter night.
