1 Brain tumors are a very common source of seizures in older pets. Itâs very unlikely your 12-year-old dog or cat will develop epilepsy. If you have a pet getting up in years who starts seizing, unfortunately, the likely cause is a brain tumor.  Bacterial, viral, fungal and parasitic infections can also cause seizures.
According to the American Water Works Association the average American home uses 45-65 gallons of total water (hot and cold) per day, per person. A little less than half of this would be for hot water uses. Therefore, as a general guide, each person in your home would use 20-30 gallons of hot water per day. If your home is water efficient then you would be toward the lower end of this scale.
What should be included: 1  Generally, a one- to two-person household needs a 30-40 gallon water heater while a household of five or more needs 50-80 gallons. However, a tank that puts out more than the household uses hourly wastes money and energy heating extra water.
