A slab leak in Carlsbad means a water line running under or through the home's concrete foundation has started to leak. Carlsbad Municipal Water District serves most of the city, with Olivenhain and Vallecitos covering parts, but the plumbing past the meter is the owner's either way. Call the number on this page to be connected with a local plumber in Carlsbad.
How the first visit goes
Your call is routed to an independent plumber who covers Carlsbad. Expect a few questions up front: what the meter did with all water use stopped, where the floor felt warm or looked damp, and when the bill started rising. On site, the plumber typically closes the house down, separates the hot side from the cold, and pressure tests each one to prove which is losing water. Only then do listening equipment and sometimes an infrared camera come out to narrow the spot. You hear the options before any concrete is touched.
What shapes the cost
- How long isolating and pinpointing the leak takes
- Whether the fix goes through the slab or reroutes new line through walls or the attic
- What sits above the leak: carpet, tile, engineered wood or a kitchen island
- Pipe type, and whether the rest of the buried run looks worn
- Drying and repair of wet drywall, baseboards or cabinets
- Any permit; the city's general rule is that work altering the structure needs one, and the Building Division at 442-339-2719 can confirm
Carlsbad homes and water
Most Carlsbad housing came with the master-planned growth of recent decades: the median home dates to about 1988, and roughly a third were built before 1980. Many of those newer houses sit on slabs, and by now the copper in the early ones has been buried long enough to wear where it rubs gravel. Older homes around the Village can have earlier piping altogether.
Water service depends on the address. Carlsbad Municipal Water District covers about 85 percent of the city, Olivenhain Municipal Water District the southern part and Vallecitos Water District the southeast, and the city points owners to its district map. Part of CMWD's supply comes from the Carlsbad Desalination Plant. If water is bubbling up on the public side in a CMWD area, the city's water and sewer emergency line is 442-339-2722 on weekdays and 760-931-2197 on evenings and weekends.
Before the plumber gets there
- Find the main shutoff and make sure it closes all the way
- Switch off irrigation controllers and any pool or fountain fill
- Mark warm or damp spots with painter's tape
- Clear a path to the water heater and the meter box
- Pull up the last few bills so the jump in usage is easy to see
