Water Heater Install & Repair
$800–$5,500 per unit
At 16-25 grains of hardness, San Diego water deposits mineral scale inside your tank faster than almost anywhere in California. That's why local water heaters often fail years before their rated lifespan. Our team handles complete replacements — including safe disconnect, haul-away, new seismic strapping, expansion tank, and city permit — so you're back to hot water fast. We install Rheem, Navien, Rinnai, and Bradford White, and we'll walk you through whether a high-efficiency tankless unit makes sense for your household size and gas line capacity.
What We Do
- Full tank water heater replacement with same-day or next-day service
- Tankless water heater installation with gas line upsizing when needed (Navien, Rinnai)
- Sediment flush and anode rod inspection to extend tank life in hard water areas
- Expansion tank and recirculation pump installation for code compliance and comfort
- California-required earthquake strapping and safe T&P valve discharge routing
- Gas and electric units — including 120V hybrid heat pump water heaters

What’s your water heater doing?
Find your symptom — we’ll tell you the most likely cause and what it usually costs to fix in San Diego. No pressure, no guesswork.
No hot water at all
Likely cause: Pilot's out, gas valve, heating element, or thermostat failure.
Repair $180–$450 · Replacement $1,400–$2,500
Water is lukewarm or runs out fast
Likely cause: Sediment buildup from San Diego's hard water, failing dip tube, or undersized tank for the household.
Flush + anode $200–$350 · Right-size replacement $1,600–$3,000
Pooling water around the base
Likely cause: Tank corrosion — usually terminal once the inner liner cracks. Shut off water and gas, then call.
Same-day replacement $1,400–$2,500 (tank)
Rusty or discolored hot water
Likely cause: Anode rod is gone and tank is rusting from the inside. Borrowed time.
Anode rod $180–$320 · Replacement if too late $1,400–$2,500
Banging, popping, or rumbling sounds
Likely cause: Mineral scale on the burner. Common in San Diego (16–25 grain hardness). Flush may save it.
Power flush $220–$380
Pilot light won't stay lit
Likely cause: Thermocouple, gas control valve, or flame sensor. Repairable on most units under 10 years old.
Repair $180–$420

Frequently Asked Questions
How much does a water heater installation cost in San Diego?
A standard tank water heater replacement in San Diego costs $800 to $2,500 including the unit, installation, permit, and haul-away. Tankless water heater installations run $3,500 to $5,500 and may require gas line upsizing. Free estimates provided.
How long does a water heater last in San Diego?
In San Diego's hard water (16-25 grains), a tank water heater typically lasts 8-12 years, vs. 10-15 years in softer-water regions. Annual sediment flushing and anode rod replacement can extend life by 2-3 years. Tankless units last 20+ years with proper maintenance.
Tank vs tankless water heater — which is better?
Tankless delivers endless hot water, saves 20-30% on energy, and lasts longer, but costs more upfront. Tanks are cheaper to install and simpler to repair. For larger homes with multiple bathrooms or high hot water demand, tankless is usually the better long-term investment. We'll assess your gas line capacity and recommend the right fit.
