Las Vegas water heater repair — tank replacement, gas + electric
Gas and electric tank water heater repair. Thermocouple, anode rod, dip tube, T&P valve, thermostat and pilot light diagnostics. Bradford White, Rheem, John Wood, A.O. Smith, GSW brands serviced.
1. THERMOCOUPLE (gas): the safety sensor at the pilot flame. If it doesn't sense the pilot, the gas valve won't stay open. Replacement: $180-$280.
2. HEATING ELEMENT (electric): tank has 1-2 heating elements. Element failure means half or no hot water. Replacement: $220-$380 per element.
3. DIP TUBE: the plastic tube that delivers cold water to the bottom of the tank. When it degrades and breaks, cold water mixes into the hot outlet. Symptom: lukewarm water even at maximum setting. Replacement: $250-$380.
4. THERMOSTAT (gas or electric): controls the temperature setpoint. Failed thermostat overheats or underheats. Replacement: $220-$380.
5. ANODE ROD (preventive): sacrificial metal rod that protects the tank lining. When it's fully corroded, the tank lining starts to fail. Replacement: $180-$280 — usually catches during maintenance, not a repair call.
Full diagnostic covers all five plus visual tank inspection for leaks or corrosion. Related in Las Vegas: AC installation and AC repair.

Repair vs replace
Leaking tank = replace, not repair
Water heater tanks last 8-12 years typical, 12-15 years with excellent maintenance. When the tank body itself starts to leak (as opposed to a fitting or connection), the tank lining has failed and there's no repair — replacement is the only fix.
For non-tank failures (thermocouple, element, thermostat, dip tube), repair almost always makes economic sense — the tank has years of life left.
The dividing line: is the tank leaking, or is a component failing? Component failures = repair. Tank body leaking = replace. We diagnose which category during the service call and quote both paths if it's a judgment call.
For rental water heaters: repairs are usually covered by the rental company at no charge. We diagnose and coordinate with the rental company if you're not sure who owns your water heater.
Depends where the leak is. Leaking fitting, valve or connection: yes, repair. Leaking from the tank body itself (bottom, side): no repair possible — the tank lining has failed. Replacement is the only fix. We diagnose which category during the service call, usually inside 15 minutes.
If you're not sure, look for a rental company sticker on the tank (Reliance, Enercare, National, etc.) or check your utility bill for a water heater rental line. Rentals are covered by the rental company at no charge for most repairs. We coordinate with them or handle the buyout if you'd rather own outright.
Thermocouple swap: 30-45 minutes. Heating element: 1-2 hours. Thermostat: 45-90 minutes. Dip tube: 2-3 hours (requires tank drain). Full tank replacement: 3-4 hours. Same-visit fixes 85% of the time.
Rule: 10+ years old with a component failure = replace, don't repair. 8-10 years and running fine: keep it, maintain the anode rod every 3-4 years. Under 8 years: repair any failure without hesitation. The math on preventive replacement (before failure) rarely works out compared to just running the tank until failure.
No hot water on a Saturday morning. Called them, tech arrived by 11am, diagnosed thermocouple, replaced in 30 minutes. Hot showers back on for the weekend.

Thermocouple swap
★★★★★
Wasn't sure if our water heater was a rental. They looked at the tank, confirmed it was, then handled the rental company call for the free repair. Zero charge to us.

Lukewarm water no matter what setting. Diagnosed a broken dip tube, replaced it, hot water is properly hot again. Great troubleshooting — 3 previous plumbers had no clue.

Dip tube fix
★★★★★
13-year-old water heater failing. They said 'this tank has weeks left, replace it now on your schedule instead of an emergency replacement.' Booked replacement for the following week, no drama.
