Many households in the US waste up to 90 gallons of water every day. That means each household almost 10,000 gallons of annual water wastage per year. Over 1 trillion by EPA estimates. The reason is poor plumbing maintenance. In most cases, it can be as simple as a worn-out toilet flapper or a leaky faucet. Now, these are easy fixes, but when left ignored, they add your water bill and in turn, cost you more for repairs.
