Main water line repair and replacement
The main water line runs from the city meter to your house. The homeowner owns this section. When it leaks, you'll often see a wet spot in the yard, low pressure or a spinning meter. A plumber locates the leak, digs to it, and repairs or replaces the line, which in Valley soil often means cutting through caliche.

Main lines in older Valley homes may be galvanized or copper. Newer ones are usually PEX or polyethylene. Leaks show up as a soggy patch in the yard or desert landscaping, or a bill spike.
Caliche can make digging slow. Plumbers may use a saw, jackhammer or directional boring to get through it.
