GALLONS OF WATER LOST DUE TO A LEAK
| Drip from faucet (about 30 drops/min) | 54 gallons/month |
| Drip from faucet (about 120 drops/min) | 237 gallons/month |
| Drip from faucet (1/2" long) | 1,000 gallons/month |
| Drip from faucet (1 1/2" long) | 2,200 gallons/month |
| Toilet overflow (undetected) | over 10,000 gallons/month |
Small, continuous leaks will waste large amounts of water. In addition, leaks in hot-water lines will waste heat.
