The episode spans several months, so my memory is fuzzy. But I recall on one occasion I got full penetration with the snake. I went to the main cleanout in the basement and saw that the snake made there. But that was before the occasion where i had /only apparently/ got full penetration, then pulled out the snake and it was permanently curled up. I think the snake was ~10—15 meters long originally. I didn’t log every attempt. Many times i only got partial penetration with the snake & made a mental note of how far but didn’t log it. There is one point that is very hard to get past… I think like 3 meters or so in.
