I'm having trouble with a plugged sewer line at my house. House is 80 years old and has two cleanouts in the basement, one is 2 inch, the other is 3 inch. I have snaked both of these with a 50 foot Marco Powerpak 60 and pulled out some balled up roots. Drain is still clogged. There is an exterior cleanout that I decided to try next. It had a brass cap on it that I could not unscrew, so I removed it with a cold chisel and hammer. The exterior vertical cleanout pipe is 3 inch. Using a flashlight, I can see 3 feet down it where it is filled with dry dirt. I tried to run the Marco rooter down it, but the dirt was dry and hard packed. I stuck a drain cleaning bladder on the end of a garden hose down there and that forced water out of the cleanouts in my basement. I'm looking for advice on how to get the dirt out of the exterior cleanout so that I can clear my line. Thanks.
