San Diego plumbing problems often come from age and water. Many homes have older copper pipes that develop pinhole leaks, slab foundations hide leaks under the floor, and the region’s hard water leaves scale in pipes and water heaters. Water saving rules also shape how homes use water.

Common plumbing problems in San Diego
Older copper pipes
Copper pipes in older homes can develop pinhole leaks over time, sometimes inside walls or under floors.
Slab leaks
Many homes sit on concrete slabs. Leaks in pipes under the slab can go unnoticed until floors feel warm or the water bill jumps.
Hard water
Much of San Diego’s water is imported and hard, leaving mineral scale on fixtures and inside water heaters.
Sewer laterals and roots
Tree roots can break into older sewer laterals, the pipe from the home to the city sewer, causing slow drains and backups.

Permits and local rules
Cleanup itself does not usually need a permit, but the repairs that follow often do. Inside the city of San Diego, larger drywall, electrical and plumbing repairs can require permits from the City of San Diego Development Services Department. Homes in other cities, such as Chula Vista, Escondido or Poway, follow the rules of that city or county.
In California, most construction and repair work above a small dollar amount must be done by a contractor licensed by the Contractors State License Board. You can check a license on the board’s website.
Seasonal risks in San Diego
If you smell gas, leave the home and call 911 or your gas company from outside. If water is near electrics, stay out of it.
- Winter storms: heavy rain can overwhelm drains and sewer laterals.
- Dry months: water saving rules limit outdoor watering.
- All year: scale builds up in pipes and water heaters.
- Any time: earthquakes can damage water lines and unstrapped water heaters.
Be prepared
- Flush your water heater once a year and make sure it is strapped
- Watch for warm floor spots or a rising water bill
- Have older sewer laterals checked with a camera
- Fix running toilets and dripping taps to save water
- Know where your main water shut off valve is
