On many Coronado properties, the main from meter to house runs beneath mature landscaping and ground where every square foot above the line is spoken for. When a main fails here, the signs are the usual ones, a wet patch that never dries, a meter that keeps turning in a quiet house, pressure that dropped everywhere, or a bill that jumped, and the ground above the leak is often landscaped, so the dig needs care.
So careful locating is worth the effort. Tracing the line and locating the leak can narrow where the contractor needs to dig, and what turns up shapes the response. A failed fitting may only need a repair at that spot, with the opening kept small. A section bent by shifting soil or corroded through gets addressed as exactly that. A line that's finished gets a conversation about replacing it, where trenchless methods can help if the route suits a pull, with small access pits instead of an open trench across landscaping that took decades.
A main leak runs continuously, and saturated ground can affect hardscape and foundations. The aim here is to head that off, with the findings put in plain English, options with tradeoffs, your decision at your pace, a licensed contractor performing the work when you're ready.
