Water heater replacement in Las Vegas: what's different
Las Vegas has some of the hardest water in the country, and scale shortens tank life dramatically. Many homes keep the water heater in the garage, where summer temperatures above 110°F add stress to the tank and relief valve.
Much of the valley was built after 1990, so original heaters are now reaching replacement age. Adding a softener or an expansion tank is common at replacement. Permits depend on the address: the City of Las Vegas, the City of Henderson, or Clark County for unincorporated areas like Paradise and Spring Valley.

No hot water? What to check first
On a gas water heater, check that the pilot is lit and the gas valve is on. On an electric heater, check the breaker and the high-limit reset button. If the pilot won't stay lit, the breaker trips again, or you smell gas, stop and call a plumber.

Repair or replace your water heater?
Repair when a replaceable part failed on a heater under about 8 years old. Replace when the tank itself leaks, the heater is past 10 to 12 years, or repairs keep adding up. A leaking tank can't be repaired.
