Plumbing Facts

Indoor plumbing dates back to at least 2500 B.C.

At 140 degrees, it takes five seconds for water to burn skin. At 160 degrees, it takes only half of a second. Your water heater should be set to no hotter than 120 degrees.

Approximately 1 in every 318 homes or buildings has a leak.

A leak the size of a pinhead can waste 360,000 gallons per year, enough to fill 12,000 bathtubs to the overflow mark.
