        "text": "The correct expansion tank size depends primarily on the size of your water heater and your home's water pressure. A general rule of thumb is that the expansion tank should be about 2 gallons for every 40 gallons of water heater capacity. However, water pressure, which can vary across Las Vegas service areas like Summerlin or Anthem, also plays a critical role. A professional plumber will calculate the precise size needed to effectively accommodate thermal expansion and protect your system based on these factors, ensuring optimal performance.",
