Please help me to figure out about this pipe.
In our hosue, We have the water pipe coming out from the wall right next to the A/C unit. Recently, the water start running constantly, and I have no know what it is.
The following points are something I am sure about.
1. The water stops running if I turn off the main valve.
2. Water was actually dripping very sometimes like 3, or 4 years ago. It is now running 3 gallons / hours.
3. It is cold water.
4. There are two pipes and joined by some kind of a T socket. 5. The pipes are nothing to do with the A/C unit; it is coming from the ground.
Please anyone give me ideas what it is and how to stop the water.
