This picture shows a 3/4" PVC fitting we found that had cracked and was leaking for a extended period of time. So much so that the water spraying out of the crack had made a smooth surface from the constant outward spraying.
TIP: Keep a eye on areas in your yard that seem wet, mushy or the grass seems to thrive during hot dry weather. If your on city water keep a eye on your water usage per your water bill. You can also ask the water service provider to look at your water meter to see if there is water going through when there is no water being used in the house. They are able to look at the meter and see if water is going through by design of the water meter. Please keep in mind that in Horry County we have black widows and they love to live in water meters. So don't do this yourself.
