A leaky toilet not only poses a property damage risk, it also poses a potential health hazard as well.
If your house was built before the mid 1970’s, the sewer line in the ground is probably a cast iron, clay, or cement piping system. Unfortunately, although good for their day, these types of lines are rather brittle, and almost without exception after some time they begin cracking from common stresses of yard movement, soil settling, and imperceptible plate tectonic activity. Once just a hair line crack has formed, it’s the beginning of the end for all these types of sewer lines. What happens next is that the moisture of the line seeps out, attracting surrounding tree roots. And once this occurs, it is not long before a root ball begins to form inside your sewer line restricting the flow, and further separating the cracks in the line. Tree roots can even shatter sewer lines completely.
According to the EPA, the average household's leaks can account for more than 10,000 gallons of water wasted every year, or the amount of water needed to wash 270 loads of laundry.
Household leaks can waste more than 1 trillion gallons annually nationwide. That's equal to the annual household water use of more than 11 million homes.
Ten percent of homes have leaks that waste 90 gallons or more per day.
Common types of leaks found in the home include worn toilet flappers, dripping faucets, and other leaking valves. All are easily correctable.
Fixing easily corrected household water leaks can save homeowners about 10 percent on their water bills.
Keep your home leak-free by repairing dripping faucets, toilet flappers, and showerheads. In most cases, fixture replacement parts don't require a major investment.
Most common leaks can be eliminated after retrofitting a household with new WaterSense labeled fixtures and other high-efficiency appliances.
