If a pipe bursts in an El Cajon home, shut the main water valve right away and keep clear of wet outlets and cords. A plumber can then find the break and replace the failed pipe or fitting. Call the number on this page to be connected with a local plumber in El Cajon.

Which water agency do I call about a break at the meter?
That depends on your address. 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. Your water bill shows which one serves you. A break at the meter, in the street or at a hydrant is the agency's job. Water leaking from the meter toward the house, or anywhere inside, is private plumbing, and that's where a plumber comes in.
Sewer is a separate system run by the City, which offers sewer lateral inspections. If water from a burst line is overflowing a sewer cleanout or manhole instead, the City lists Public Works Operations at (619) 441-1658 during business hours and the El Cajon Police at (619) 579-3311 after hours.
Why do so many older El Cajon homes spring leaks?
The median El Cajon home was built around 1974, so many houses still have supply and drain piping from that era. Fifty-year-old copper joints, galvanized steel sections and original shutoff valves are the parts most likely to crack, corrode through or refuse to close in an emergency. Helix also reports hard water, with plant water averaging 206 mg/L, about 12 grains per gallon, and scale adds wear to valves and connections. El Cajon's valley location brings hot summers and colder winter nights than the coast, so pipes on outside walls and hose bibs get more temperature swing too.
Will I need to replace more than the broken piece?
Often a single repair coupling or a short new section is enough. But in a house of El Cajon's typical age, the plumber may find corrosion or pinholes along the same run, and replacing that section avoids a second break next month. If the home has had several failures, it may be time to talk about repiping. The City's Building Safety Division, at 619-441-1726, can confirm whether a larger replacement needs a permit.
A local note
Before you need it, find your main shutoff and test that it turns. In older El Cajon houses the valve is often stiff or partly seized, and knowing that in advance means a plumber can replace it on a calm day rather than during a flood.
