Frequently Asked Questions: Pinhole Leak in Copper Pipe
What causes pinhole leak in copper pipe in Sun Lakes homes?
Pitting corrosion caused by high-pH chloraminated municipal water, aggressive dissolved silica, mechanical erosion from excessive water velocity, and chemical reactions with Sonoran desert soil. In Sun Lakes, water hardness of 15-22 GPG and high static pressure accelerate these mechanical issues.
Can this issue cause permanent damage if left unaddressed?
Yes. Hidden plumbing leaks or sewer line back-pressures can erode soil beneath foundations, ruin drywall, and trigger costly microbial growth within 24-48 hours.
