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.
Estimating Home Water Use Needs. In general, we use 50 to 100 gallons per person per day in our homes (200 to 400 gallons per day for a family of four). The household water use estimates given in Table 1 can be used to calculate more specific daily water use values for your home. For the purposes of planning a water system, the total daily water use is less important than the peak daily water use or the peak demand.
