In a Del Mar plumbing emergency, close the main valve to stop the water; any gas smell means getting outside first and calling 911 and SDG&E at 1-800-611-7343 from there. Then call the number on this page to be connected with a local plumber in Del Mar.

Problems that justify a call tonight
- A burst or leaking pipe that keeps soaking a wall, ceiling or cabinet
- Sewage coming up through a shower, tub or toilet
- A water heater leaking from the tank
- Running water you can hear but can't find
- Any gas odor in or around the house
A drip or a slow sink can be booked for a weekday. Spreading water, sewage and gas cannot wait.
How Del Mar's systems work
The City of Del Mar runs its own water system. It buys untreated water from the San Diego County Water Authority, has it treated by the City of San Diego at the Miramar plant, and stores it in four City reservoirs. The water is chloraminated and hard, averaging 229 ppm, about 13.4 grains per gallon, and that scale slowly works on water heaters and valves. For a problem with the City system, Public Works is at (858) 755-3294 at any hour, and after hours North County Dispatch can be reached at 858-756-1126.
The City maintains the public sewer, but the private lateral from the house to the City main belongs to the owner. The City says most sewer backups come from clogged private plumbing, so residents should call a private plumber first and contact Public Works only if they suspect the City system. Del Mar also has no records of private laterals, because the City didn't install them, so a plumber has to locate yours. Repairs that reach into the public right of way need an encroachment permit. With the City focused on keeping sewage out of its beaches and lagoons, a backup is worth handling quickly.
SDG&E supplies gas. Leave the house at the first sign of a leak and call from a safe distance.
Factors in the price
- Time of day. After-hours and weekend work usually costs more.
- Finding the line. With no City records of private laterals, locating yours may take a camera or locator.
- Right-of-way work. A lateral break past the property line adds an encroachment permit.
- Permits. Plumbing permits go through Building & Safety Services and can be applied for online via eTRAKiT.
Once you call
You'll be connected with an independent plumber who handles urgent work in Del Mar. Give the address, say whether the main is closed and describe what's happening. Ask how night and weekend pricing works before booking. Arrival time depends on the hour and the plumber's schedule, so none is promised.
