Frequently Asked Questions About Water Heater Installation in Sunnyvale
The cost of water heater installation in Sunnyvale, CA usually ranges from $1,200 to $3,500, depending on the type of water heater (tank vs. tankless), its capacity, fuel type (gas or electric) and any needed plumbing or electrical modifications. We provide a written, upfront quote after assessing your particular needs.
Manufacturer warranties usually range from 6 to 12 years on the tank and parts. We also warranty our installation labor.
If your home has a pressure reducing valve or check valve, an expansion tank is typically required. It protects your water heater and pipes from pressure spikes.
The average lifespan of a traditional tank water heater is about 10 to 15 years, while tankless water heaters can last 20 years or more with proper maintenance. Factors like local water quality, maintenance frequency and usage habits can all influence the actual lifespan of your unit. Regular flushing can help extend its life.
New water heaters usually come with a manufacturer's warranty on the tank and components, usually ranging from 6 to 12 years. FBL Plumbing also provides a labor warranty on our installation work, ensuring peace of mind. We will discuss specific warranty details for your chosen unit during the consultation.
While it might seem like a DIY project, water heater installation involves working with gas lines, high voltage electricity and water connections, all of which carry significant risks if not handled correctly. Improper installation can lead to leaks, gas explosions, electrical fires and carbon monoxide poisoning. It can also void your warranty, and local codes typically require a licensed plumber for this work.
Many tank water heaters last 8 to 12 years, though hard water can shorten that. Regular flushing and anode rod checks help lengthen life.
Most standard water heater installations, particularly for replacing a similar tank unit, can be completed within 3 to 4 hours. However, a conversion from a tank to a tankless system, or installations requiring significant plumbing or electrical modifications, might take a full day or longer. We will provide an estimated timeline during our first assessment.
