If a pipe bursts or a drain overflows in an El Cajon home, close the main water valve right away; if you smell gas, get everyone out and call 911 and SDG&E at 1-800-611-7343 from outside. Then call the number on this page to be connected with a local plumber in El Cajon.

Which water district do I call if the leak is at the meter?
That depends on your street. The City of El Cajon lists two water providers, Helix Water District at 619-466-0585 and Padre Dam Municipal Water District at 619-448-3111, and the name on your water bill tells you which one serves your address. Water bubbling from the meter box or the street belongs to that district. Everything from the meter into the house, from a split pipe in the garage to a failed supply hose behind the toilet, is plumber work. Close the house shutoff first so the damage stops growing while you sort that out.
What if sewage is overflowing in the street rather than in my house?
The City of El Cajon runs the wastewater collection system through its Engineering Services and Public Works Operations teams. An overflow from a manhole or a main goes to Public Works Operations at (619) 441-1658 during business hours, and to El Cajon Police at (619) 579-3311 after hours. When only your home is backing up, the blockage is usually in your own sewer lateral, and a plumber can clear it. The City also offers sewer lateral inspections, which can be useful after an emergency repair to understand the condition of the rest of the line.
Why do so many El Cajon emergencies involve old pipes and water heaters?
The median El Cajon home was built around 1974, so many houses still have original-era supply and drain piping, and the valves meant to stop a leak can be stiff or seized after decades. For Helix-served homes, treated water averages about 12 grains per gallon of hardness, and that scale builds up in water heater tanks and valve seats until something gives. Padre Dam customers should check their own district's water report.
Gas is its own category. SDG&E is the gas utility, and it states that customers are responsible for the gas lines on their side of the meter, including underground lines running to buildings or equipment. If you smell gas, leave first, then call 911 and SDG&E from a safe distance. A plumber can repair customer-side gas piping once the area is safe.
One local note
When you call, give the address with a familiar landmark, such as the nearest Main Street cross street, Fletcher Hills, Bostonia or the roads around Parkway Plaza, and say whether the main is off. Ask how after-hours pricing works before the visit is booked; nights and weekends usually cost more. The City's Building Safety Division (619-441-1726) handles permits, and the plumber can confirm with it whether a larger repair needs one. No arrival time is promised, since it depends on the hour and the plumber's schedule.
