I live in central florida and the main pipe coming off the street and into my house is copper. The pipe comes out of the ground about 16" and then there is a right angle elbow. The inside corner of the elbow hits right against the stucko of my house (wood construction). Today I noticed 1 sprouting pinhole leak and 1 drilling pinhole leak on the outter side of the elbow (so it's exterior of the house).
The pipes are 23-24 years old (assuming original pipe). The pipe has always been painted.
How common is something like this? And more importantly, am I too expect future leaks to happen to other pipes that are inside the slab or inside my walls? The plumber I spoke with said it may happen, and it can be common. I really hope this is just a freak thing because it's an exterior pipe.
