|Checking for leaks
If a leak is detected, likely culprits are toilets and irrigation systems.
• Checking for toilet leaks
1. Put 3-5 drops of food coloring in the toilet tank.
2. After 1 hour, check the toilet bowl to see if colored water has escaped into it from the tank.
3. If you see colored water in the bowl, the toilet probably has a flapper leak. Replace or readjust the flapper.
• Checking for irrigation leaks
1. Taller, greener vegetation or moss growing around the sprinkler heads are signs of a damaged or dirty valve. Clean and replace worn parts.
2. Wet spots, mud, and eroding soil may indicate a broken pipe. Dry spots in your lawn could also be a sign that a sprinkler is damaged. To locate the source of the leak, dig around the sprinkler.
3. Wet spots on pavement also indicate possible leaks. Watch your sprinklers to determine which one is showering the pavement. Turn off the water, and check the sprinkler head and riser. Sprinklers spouting geysers indicate broken sprinkler heads. Replace them.
