A Del Mar water heater that leaks from the tank, gives off rusty or short-lived hot water, or shows heavy corrosion is usually ready to be replaced. Plumbing permits in Del Mar are applied for online through the city's eTRAKiT system with Building & Safety Services. Call the number on this page to be connected with a local plumber in Del Mar.

Warning signs
- A wet floor or rust trail at the base of the tank
- Crusty white or green buildup around the fittings on top
- Rust on the burner door, gas valve or vent cap
- Rumbling or popping when the burner fires
- Hot water that's cloudy, brown or runs out early
Some of these, like a weak pilot or a dripping relief valve, can be repairs on a newer heater. A leaking tank cannot.
Del Mar details that shape the job
The City of Del Mar runs its own water system. It buys untreated water from the San Diego County Water Authority, has it treated at the City of San Diego's Miramar plant, and stores it in four city reservoirs. The city's 2024 report puts total hardness at an average of 229 ppm, or 13.4 grains per gallon. That's hard water, and it builds scale on the tank floor and heating elements year after year. The water is also chloraminated, which can be tough on rubber seals in valves and connectors. Flushing the tank annually and checking the anode rod every few years go a long way.
As a small coastal city, Del Mar adds salt air to the picture, which is hard on any heater in an exterior closet or open garage. Plumbing permits go through Building & Safety Services, with plan review performed by EsGil Corporation for the city; building inquiries go to (858) 375-9514. Gas comes from SDG&E. If you smell gas near the heater, leave the house first, then call 911 and SDG&E at 1-800-611-7343 from outside.
What moves the price
- Tank, tankless or heat pump, and the size you need
- Venting and gas line work, especially for a tankless conversion
- Corrosion-resistant parts for exposed coastal installs
- Earthquake straps, a drain pan or an expansion tank
- Tight access in older or hillside homes
- Permit handling and hauling away the old tank
