I have an A/C condensation drain line that's blocked, and I'm having trouble using a snake to get to the blockage. The pipe is 3/4" PVC with many 90 degree elbows.
I tried using a regular drain snake (1/4") but I can't get it past one of the 90 degree elbows (and there are several more). I did see this post about replacing the elbows with more friendly corners, but there are a couple elbows that would require opening a wall to access.
Am I using my snake incorrectly? Is there a better way to clear the line?
