Do I need to flush water lines after using flux?
As a homeowner embarking on a DIY plumbing project, I'm curious about the necessary steps to ensure a smooth and efficient pipe installation. Specifically, I've read about using flux as a joining agent for soldering copper pipes. However, I'm unclear about whether it's essential to flush the water lines after applying flux. Could you elaborate on the importance of flushing, potential risks if not flushed, and the recommended procedure for doing so? I'd appreciate your insight into this crucial aspect of the plumbing process.
