Plumbing services in Alpine
Alpine at a glance
Alpine is an unincorporated community in San Diego County's East County, around 27 miles from downtown San Diego in a straight line and past Lakeside and El Cajon. The 2020 Census put its population at 14,696. Higher East County areas like this see colder winter nights than the coast, so exposed pipes, outdoor spigots and well equipment deserve some protection when a cold snap is forecast.
Most of the area is on wells
The County's environmental review for the Alpine Community Plan says Padre Dam Municipal Water District serves only the central-western part of the community, the portion inside the San Diego County Water Authority boundary. The rest, about 81 percent of the plan area by land, depends on groundwater from on-site private wells or small water systems. That land share is not a household count, but it means well pumps, pressure tanks, pressure switches and water treatment equipment are everyday plumbing topics in Alpine, not side jobs. If your home is on a well, say so when you call.
Sewer covers a small part
The San Diego County Sanitation District, formerly the Alpine Sewer Service Area, serves part of the community, and what it collects is treated at the City of San Diego's Point Loma plant. The County's review says roughly 98 percent of the plan area instead uses private onsite wastewater systems. For those homes, a plumber handles the drain line from the house out to the tank in the same way as any building drain: clearing clogs, finding breaks and replacing damaged pipe.
Housing age
The median Alpine home was built around 1986, and about 38.1 percent of units predate 1980. Newer houses can still need water heater replacement, fixture work and leak repair, while older ones may also be ready for new supply piping.
Gas or propane
The County's review says SDG&E provides electricity and natural gas throughout the county, though it does not say whether gas mains reach every Alpine parcel, and some backcountry homes use propane or are all-electric. For a natural gas smell, go outside first, then call 911 and SDG&E at 1-800-611-7343 from a safe location. If your home uses propane, leave and call 911 and your propane supplier.
Permits
Alpine is unincorporated, so permits go through the County of San Diego for unincorporated areas.
Different from city plumbing
In the City of San Diego, practically every home is on city water and city sewer. In Alpine, a plumber may be dealing with a well, a small water system or an onsite wastewater system, and the answer changes from one road to the next. When you call the number on this page, describe the problem and whether you are on well or district water, and you will be connected with an independent plumber who sets the price and timing with you.
