Your side of the meter
Who owns which part of the pipe
Most residents of San Antonio Heights are shareholders in the San Antonio Water Company, a mutual water company, and that arrangement shapes who you call. Generally the water company looks after its mains and the meter, while the service line running from the meter to the house, plus every pipe inside, is the homeowner’s to maintain.
That service line is the part most people never think about until it fails. A wet patch in the yard, a meter dial that keeps turning with every tap closed, or a sudden drop in pressure can all point to a leak underground. Our crews use line-locating gear to trace where the pipe runs before deciding where to dig.
Shutoff valves are the other half of this work. The main shutoff and the small valves under sinks and behind toilets are what stop a leak from becoming a flood, and a valve that is stuck open or drips when turned is worth replacing before you need it. Main water line repair falls under the same visit.

In the foothills
Above Upland, below Mount Baldy
San Antonio Heights sits in the foothills of the San Gabriel Mountains, directly north of Upland, with Mount San Antonio, known to most people as Mount Baldy, rising to the north. It is an unincorporated community of San Bernardino County rather than a city, and it borders Upland and Rancho Cucamonga.
Rancho Cucamonga, where our shop is, sits right beside the Heights, so this community is part of our regular service area rather than a special trip. Crews keep the same hours here as everywhere else, 7:00 AM to 5:00 PM seven days a week, with evening and weekend visits on request.
Before any digging on a property, it pays to know what is underground. Our trucks carry line-locating equipment for water, sewer and gas lines, which lets a crew mark the route of a buried pipe and keep the excavation to the area the repair actually needs.
Water line questions from San Antonio Heights
- Should I call the San Antonio Water Company or a plumber?
- Call the water company for problems at its main or at the meter, and call a plumber for anything between the meter and your house. Generally the water company is responsible up to and including the meter, and the homeowner is responsible from there inward. If you are not sure where a leak is, a plumber can trace it and tell you whose side it is on.
- How do I know my water service line is leaking?
- The clearest sign is a meter that keeps moving while every tap and appliance in the house is off. Other clues include a soggy area in the yard that never dries, the sound of running water with nothing on, and a drop in pressure. A plumber can confirm the leak and locate the pipe before any digging starts.
- Where is my main water shutoff?
- In most homes the main shutoff sits where the water line enters the house, and the meter has its own valve on the water company’s side. Finding yours before an emergency saves time when a pipe bursts. If the valve is seized or leaks when you turn it, we can replace it.
- Do you serve all of San Antonio Heights?
- Yes, San Antonio Heights is within our service area, along with its neighbors Upland and Rancho Cucamonga. Our shop is in Rancho Cucamonga, and the same crews cover the community. Same-day visits are sometimes possible, depending on that day’s schedule.
- What if a pipe bursts at night?
- Close the main shutoff first, keep people clear of the water, and call (657) 632-8881. Emergency support is available 24/7 for burst pipes and no-water calls. A service fee applies outside normal hours, and the office tells you what it is before a crew is sent.
