Tank Water Heater Installation & Repair in Marin & Sonoma
Local Plumbing — Water Heater Specialists
If your water heater is leaking, not producing enough hot water, or is more than 8–10 years old, Local Plumbing provides fast, professional tank water heater repair and installation across Marin, Sonoma, and Napa counties.
Our go-to brand is American Standard, but we replace and repair all major water heater brands, including Rheem, Bradford White, State, and AO Smith.
We install standard gas and electric tanks in sizes ranging from 40 to 75 gallons, including high-recovery models for larger families.
Why Homeowners Choose Local Plumbing
Replacing a tank water heater is more than “swapping a unit.” Every installation must:
- Meet California code
- Be strapped and braced for earthquakes
- Have a proper gas shutoff and flex line
- Have a correctly sized flue or vent system
- Include an expansion tank where required
- Maintain safe temperature + pressure control
- Be properly drained and disposed of
We handle all of it with clean, professional installation — same day whenever possible.
