In Lake Elsinore, a water heater usually gets replaced once the tank leaks, the hot water turns rusty, or scale and age have cut the unit's output. The City of Lake Elsinore Building & Safety Division requires a permit to install, alter, repair or replace any plumbing or gas system.

Why do water heaters build up so much scale in Lake Elsinore?
Elsinore Valley Municipal Water District supplies the city with a blend of imported water and local groundwater, and hardness differs a lot by source. EVMWD's 2025 water quality report lists the Elsinore groundwater blend at an average of 338 ppm as calcium carbonate (range 230 to 400), EMWD imported water at 217 ppm, Western Municipal Water District imported water at 93 ppm and Temescal groundwater at 203 ppm. Hardness at the tap therefore changes by area and season, and some homes get very hard water. That hardness ends up as scale on the bottom of tanks and inside tankless heat exchangers, which is why noisy, short-on-capacity heaters are common here. EVMWD disinfects with chlorine.
Who handles what when the old heater comes out?
EVMWD maintains everything through the meter box; leaks on the house side of the meter box are the property owner's responsibility. The heater, its valves and the house piping are yours to repair or replace, and that's where a plumber comes in. If the main shutoff won't close, EVMWD can be reached at (951) 674-3146. EVMWD also reports no lead or galvanized-requiring-replacement service lines in its system, though it notes customer-owned plumbing may still contain lead.
What does the city require for the new heater?
The City of Lake Elsinore Building & Safety Division says permits are required to install, alter, repair or replace any plumbing or gas system, which covers a water heater swap. The division can be reached at (951) 674-3124, and the city offers an online Citizen Self Service portal. The plumber usually pulls the permit and schedules the inspection, where seismic straps, the vent, the gas connector and the relief valve discharge are checked. Expect the inspector to look closely at strapping, since California requires it.
A local note
With water this hard in parts of the city, it's worth asking about a softener or at least a regular flushing plan when you replace the heater. SoCalGas is the gas utility: if you smell gas, leave the house first, then call 911 and SoCalGas at 1-800-427-2200 from outside.
