Install expansion tank on water heater in Oklahoma
Last updated: September 24, 2026
WaterHeater Pros serves Oklahoma, a state characterized by its significant temperature fluctuations and a history of robust housing development, particularly within its major metropolitan areas like Tulsa. The climate, ranging from hot summers to cold, often windy winters, places considerable demand on residential water heating systems, necessitating regular maintenance and efficient operation to prevent system failures during peak usage periods.

In Oklahoma, the installation of an expansion tank on a water heater is a crucial consideration due to the thermal expansion that occurs as water is heated, particularly within closed plumbing systems common in older homes found throughout Tulsa and surrounding communities. This expansion can lead to excessive pressure within the tank and piping, potentially causing damage to the water heater itself, plumbing fixtures, and even appliance components. A properly sized and installed thermal expansion tank, typically a bladder-type or diaphragm-type unit, absorbs this excess volume, mitigating pressure spikes and extending the lifespan of your water heating infrastructure. Ensuring compliance with local plumbing codes, which may mandate the inclusion of such devices depending on the system configuration and local amendments to the International Plumbing Code, is paramount for a safe and reliable installation.
Common questions
What is the average cost of installing a tankless hot water heater?
The cost of installing a tankless water heater is influenced by factors such as the unit's flow rate capacity, energy source (gas or electric), and any necessary modifications to existing venting or gas lines. Our team provides a detailed assessment to determine the precise investment required for your specific application, offering a free phone quote.
What is the downside to tankless water heaters?
A primary consideration with tankless water heaters is the potential for a slight delay in hot water delivery, often referred to as the 'cold water sandwich' effect, especially in larger homes or during periods of high demand. The initial installation cost is also generally higher than that of traditional tank units, though long-term energy savings can offset this.
Can you run two showers with a tankless water heater?
The ability to run two showers simultaneously with a tankless water heater is contingent upon the unit's Gallons Per Minute (GPM) flow rate and the fixture's flow requirements. Higher GPM models are designed to accommodate multiple simultaneous uses, ensuring consistent hot water delivery for households in areas like Tulsa.
How long do hot water heaters typically last?
Traditional tank water heaters generally have a lifespan of 10 to 15 years, while tankless models can often last 20 years or more with proper maintenance. Factors such as water quality, installation quality, and routine servicing significantly impact the longevity of any water heating system in Oklahoma.
What is the average cost of putting in a water heater?
The cost of installing a new water heater is determined by the type of unit (tank or tankless), its capacity or flow rate, and any necessary modifications to the installation site, such as plumbing or venting adjustments. We offer a comprehensive evaluation and provide a free phone quote to detail the investment for your Oklahoma residence.
What is the downside to tankless water heaters?
A potential drawback of tankless water heaters is the initial cost of acquisition and installation, which is typically higher than that of conventional tank models. Furthermore, some units may experience a brief delay in hot water delivery as they activate, and their continuous operation can sometimes be limited by the maximum flow rate.
