A Carson City homeowner reported complete water loss to the property after a previous contractor shut off supply at the street. Riley Heating Plumbing And Air traced the issue to a failed check valve on an exterior line and found significant corrosion at the original fitting. The technician excavated the affected section, cut back to clean copper, and installed a new brass shut-off valve with properly sweated joints. Water service was restored and pressure tested before backfill. Call Riley Heating Plumbing And Air when plumbing services require more than a surface fix.
