I was called to a home to replace a leaking 3/4 elbow for the condensate drain. When I arrived, I found that the existing elbow was corroded and leaking. I removed the old elbow and installed a new one, ensuring a tight seal. I also checked the drain line for any other issues and made the necessary repairs. Finally, I tested the drain line to ensure it was working properly. The homeowner was very pleased with the work and thanked me for my help.
