When the shower suddenly runs cold or your water heater starts rumbling like an old tractor, you know something’s wrong. In homes across Sonoma County, water heater issues are among the most common plumbing problems and knowing when to repair, maintain, or replace your system can save you a lot of frustration and money.
At Benjamin Franklin Plumbing, we specialize in water heater repair in Sonoma County, serving both traditional tank-style and modern tankless units. Whether you live in downtown Sonoma, Boyes Hot Springs, or Glen Ellen, our licensed technicians know the unique challenges that come with local water quality and hard mineral buildup.
Let’s break down how each type of water heater works, the problems that typically arise, and what proactive homeowners can do to extend their system’s lifespan.
Understanding the Difference: Tank vs. Tankless
Before you can decide what’s wrong, or how to fix it, it helps to know how your system functions.
Tank Water Heaters
These are the classic models found in most homes across Sonoma County. They heat and store a fixed amount of water (usually 40–80 gallons) inside an insulated tank, keeping it ready for use.
Common issues that require water heater repair in Sonoma County include:
- Sediment buildup from minerals in local water
- Rust or corrosion inside the tank
- Faulty thermostats or heating elements
- Leaking fittings or pressure valves
If you hear popping or rumbling sounds, it’s likely sediment at the bottom of the tank boiling as water heats.
Tankless Water Heaters
Tankless, or “on-demand,” units heat water only as you need it, saving energy and space. While they’re more efficient, they still require professional water heater repair in Sonoma County for issues like:
- Scale buildup on heating elements
- Blocked air or gas lines
- Faulty sensors or ignition failures
- Water flow inconsistencies
Tankless systems tend to last longer than traditional ones, up to 20 years with proper maintenance, but they’re also more sensitive to neglect.
Common Signs You Need Water Heater Repair in Sonoma County
Whether you have a tank or tankless model, there are some universal warning signs that it’s time to call a professional:
- Inconsistent or no hot water – Likely a heating element or ignition problem.
- Discolored or rusty water – Indicates corrosion or a deteriorating anode rod
- Strange noises – Rumbling or banging means sediment buildup
- Leaking around the base – Could signal valve failure or internal tank corrosion
- Fluctuating temperatures – Common in both systems when thermostats or flow sensors fail
Don’t wait for complete system failure. Timely water heater repair in Sonoma County can often extend the life of your current unit by several years.
The Role of Sonoma County’s Water Quality
One of the most common causes of water heater problems here is mineral buildup. Sonoma County water, while generally safe and clean, often contains calcium and magnesium — minerals that lead to “hard water.”
Over time, these minerals settle at the bottom of your tank or form scale inside a tankless system, making it harder for the unit to heat efficiently.
Our technicians perform descaling and flushing services during water heater repair in Sonoma County to remove buildup, restore performance, and prevent damage to internal components.
When to Repair vs. Replace
Sometimes repair is the right move, other times, replacement makes more sense. Our goal during water heater repair in Sonoma County is always to save you money, not push unnecessary replacements. We provide honest recommendations based on your unit’s age, condition, and efficiency.
Here’s a simple guide to help you decide:
| Condition | Tank Water Heater | Tankless Water Heater | Recommended Action |
| Unit age | 8–12 years | 15–20 years | Consider replacement if older than range |
| Water is rusty or leaking | Often corrosion | Rare unless from connections | Replace for safety |
| Only warm or cold water | Thermostat or element | Sensor or flow issue | Repair if under 10 years |
| Strange noises | Sediment buildup | Scale accumulation | Flush & maintain |
| Frequent breakdowns | Signs of end-of-life | Unusual for tankless | Replacement advised |
