Expansion Tank Installation in Kennewick, WA
Many homes have a pressure reducing valve or check valve that creates a closed system. When water heats and expands, pressure can rise and stress pipes and relief valves.

Frequently Asked Questions About Water Heater Installation in Kennewick
A standard 40 to 50 gallon tank water heater usually costs $1,600 to $3,500 installed. Tankless installations often run $3,000 to $6,500 depending on gas line and venting needs.
If your home has a pressure reducing valve or check valve, an expansion tank is usually required. It protects your water heater and pipes from pressure spikes.
Many tank water heaters last 8 to 12 years, though hard water can shorten that. Regular flushing and anode rod checks help lengthen life.
In most areas, a plumbing permit is required for water heater replacement or installation to ensure the work meets local building and safety codes. Plumbers in Washington must hold a state certification, and water heater replacements and repiping usually require a permit. FHN Plumbing handles all necessary permit applications and inspections in Kennewick as part of our service.
Most standard water heater installations, especially 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 initial assessment.
To improve efficiency, ensure your new water heater is properly sized for your home, consider a tankless model for on-demand heating, insulate hot water pipes and set the thermostat to 120°F (49°C) to prevent scalding and cut energy consumption.
A traditional tank water heater typically lasts between 8 and 12 years with proper maintenance. Tankless water heaters often have a longer lifespan, ranging from 15 to 20 years, thanks to their durable components and on-demand operation.
Manufacturer warranties usually range from 6 to 12 years on the tank and parts. We also warranty our installation labor.

A pipe burst at 11 pm and they actually answered. The plumber showed up within the hour, shut everything down, and had us back to normal the next morning. Could not ask for more.
