Age is the biggest factor. If your water heater is under 8 years old, a repair is usually the right call. If it’s 10+ years old and having issues, replacement is almost always more cost-effective — repairs on an aging unit tend to cascade. Rust-colored water, visible tank leaks, or severe sediment buildup typically mean replacement regardless of age.

Our plumber will diagnose it honestly and give you both options.

Conventional tank water heaters typically last 10–12 years. Tankless water heaters last significantly longer — often 20+ years with proper maintenance. Heat pump/hybrid models are similar to tankless in lifespan. Annual flushing and anode rod maintenance extend the life of any water heater considerably.

For most Southern California homes, yes. Tankless heaters provide endless hot water on demand, eliminate standby energy loss, and last twice as long as conventional tanks. SoCalGas offers rebates of $150–$200 on qualifying natural gas tankless models, which significantly offset the higher upfront cost. The break-even point on energy savings is typically 3–5 years.

The main limitation: simultaneous high-demand use (e.g., two showers running at once) can push the flow rate limit on a single unit. Properly sized units handle most household needs without issue.

SoCalGas currently offers: $100 rebate on Energy Star certified high-efficiency natural gas tank water heaters (Energy Factor 0.67 or higher); and $150–$200 rebate on qualifying Energy Star certified natural gas tankless water heaters depending on the model’s energy factor. Federal tax credits may also apply to heat pump water heater installations. Ask your Team Rooter plumber which models qualify at the time of your service.

Yes — same-day water heater replacement is available when you call before midday and we have the right unit in stock or available locally. Standard residential tank water heaters (40 and 50 gallon, gas and electric) are typically same-day. Specialty units, large commercial tanks, and some tankless models may require next-day scheduling while the unit is sourced.

A repeatedly failing pilot light usually points to one of three causes: a dirty or failing thermocouple (the safety sensor that keeps the gas valve open when the pilot is lit), a blocked or dirty pilot orifice, or a faulty gas valve. The thermocouple is the most common culprit and is typically an inexpensive repair. Call (800) 818-2397 — we can usually diagnose and fix this same day.

Yes — a rotten egg or sulfur smell in hot water is almost always caused by a failing anode rod in the water heater reacting with certain minerals or bacteria in the water. This is common in areas with hard water or well water. The fix is usually anode rod replacement and a tank flush. If left unaddressed, it accelerates tank corrosion.

Once a year is the standard recommendation. Southern California’s hard water accelerates sediment buildup on the bottom of tank water heaters, which reduces efficiency, increases energy bills, and shortens the tank’s lifespan. An annual flush removes the sediment and significantly extends the life of your water heater.

Technically possible but not recommended in California. Water heater installations in California require a permit and inspection in most cities. Unpermitted work can create problems when selling your home, void manufacturer warranties, and present real safety risks — particularly with gas appliances. A licensed plumber handles the permit, installation, and inspection sign-off. Call Team Rooter at (800) 818-2397.

We install and service all major brands including Bradford White, Rheem, AO Smith, Navien, Rinnai, Noritz, State, and more. For replacement units, we recommend the model that best fits your home’s hot water demand, existing fuel type, and budget — and we’ll tell you honestly which models qualify for rebates before you decide.
