Thats some funny stuff. I crawled a house for a telephone call and after I low crawled through a very damp area, I returned another route and saw that the toilet stack was broken and the damp area was creep from a larger pool of stank, visible toilet paper wads and all! I kept it down until I crawled out, then puked. Took the crawl suit off and threw it away, and called work saying I was driving home to take a shower. They had no objection to that. I may end up doing the whole intersection with PVC as advised. It looks easy once I get the y's and everything set up. Hardest part will be cutting the cast iron, My Homie Depot rents the pipe cracker for $25 for 4 hours. Thats about the cost of a diamond blade
