Bears live primarily in the forest and they have a remarkable way of adapting to people moving in to their territory. Black bears eat berries, nuts, tubers, roots, honey, worms, buds, leaves, fruit, twigs, grubs, fish, insects, and small mammals. In the spring, black bears even eat the inside layer of young trees. They must eat between 11 and 18 pounds of food each day to stay healthy. Black bears hibernate during the winter months.
Water should be boiled for at least 3 to 5 minutes to sanitize it. Some agencies recommend boiling for 10 minutes just to be safe. If you live at high altitudes, add a minute for every 1000 feet above sea level.
Technically, you should NOT pour boiling water down a PVC drain. PVC is rated for use up to 140 degrees F. Water boils at 212 degrees. PVC is not intended for hot water service. For you to see a problem right away, the boiling water would have to be in contact with the pipe for a prolonged period of time.
