I was just wondering some of the strange things pulled back on sewer calls. One time I was in a lawyers office. The building was moved to its current location around 100 years ago. The place is ancient. Well there was a clogged upstairs toilet they always had issues with. We only had our small machine on the truck so we ran it and it worked fine. We got a call back and brought the big machine. We couldn't get the cable to go more than about a foot. The guy I used to work with reached his arm in and found plywood from the last remodel which they claimed was in the 60's. We got the plywood out and things were fine again. Then we get another call back so we run the big machine again....about 25' foot in and we hit dirt. We dont have a camera so unfortunately that's the last I saw of the place but whoever got to go back was going to hate life. The upstairs drop cones into the crawl, offsets then goes into the ground and with the amount of cable we were still under the building and not outside in a very shallow crawl.
