Most of Fallbrook gets water, wastewater and recycled water service from Fallbrook Public Utility District, and leaks on the property side of the water meter are the owner's to fix. As an unincorporated community, Fallbrook's permits go through the County of San Diego. Plumber Oceanside is a free referral line that does no plumbing work; call the number on this page to be connected with a local plumber in Fallbrook.

Plumbing services in Fallbrook
Unincorporated North County, northeast of Oceanside
Fallbrook is an unincorporated community in northern San Diego County, about 14 miles from central Oceanside in a straight line. The 2020 Census counted about 32,300 residents. Old Highway 395 runs along its eastern side, the Santa Margarita River runs through the area, and Pala Mesa Resort sits in the greater Fallbrook area. Inland, summers are hotter and drier than at the coast, and cold nights can bring frost to exposed pipes.
Fallbrook Public Utility District
Fallbrook Public Utility District (FPUD) was formed to supply water to the community and serves about 35,000 people across a 28,000-acre service area, providing water, wastewater and recycled water. Its supply combines imported Colorado River and State Water Project water, treated at Metropolitan's Lake Skinner plant near Temecula, with local water from the Santa Margarita River through the district's Conjunctive Use Project. The Mission Resource Conservation District describes the local groundwater as treated with reverse osmosis and UV. FPUD's annual water quality report is the place to look up hardness and disinfection for your tap. Some addresses at the edges of the Fallbrook area fall inside Rainbow Municipal Water District instead, so check your bill.
FPUD's rule on leaks is simple: the district handles leaks at the meter, in the street or at a hydrant, and the customer repairs leaks on the property's side of the meter. The meter is usually near the front of the lot facing the street. FPUD can be reached at (760) 728-1125, and it publishes an interactive lead and copper service line map showing pipe materials across its service area.
Sewer and rural parcels
FPUD treats wastewater and runs a Fats, Oils and Grease program to cut down on sewer overflows, so keeping cooking grease out of the kitchen drain matters here. Not every parcel around Fallbrook is on municipal sewer; some rural properties use a private onsite wastewater system, and for those the plumbing work centers on the line from the house to the tank. No housing-age figure was confirmed for Fallbrook, so a plumber's first look at pipe materials is worthwhile on an older or rural property.
Permits
Because Fallbrook is not a city, permits for plumbing work at unincorporated addresses go through the County of San Diego rather than a city building department.
Gas and propane
SDG&E is the gas utility for San Diego County. If you smell gas, leave the house first, then call 911 and SDG&E at 1-800-611-7343 from outside. Some rural homes may use propane instead; in that case leave, then call 911 and your propane supplier.
Unlike Oceanside, and calling
Oceanside homes are on City water and sewer with a city permit office. Fallbrook has a utility district, county permits and some properties off the sewer system. Call the number on this page, describe the problem and whether you are on sewer, and you will be connected with an independent plumber in Fallbrook who quotes the job directly.
