USA Pipe Repair was called out to clear a line which had been causing issues for multiple days. After finding that the toilets were on a t and not a y we decided to work from the vent pipe on the roof. We jetted the line to clear the clog and after the water went down we inspected the pipe.
We found that we had not completely removed the problem because there was a metal door stopper ring wedged in the pipe. After a little bit of work we were able to get the jetter past it and then use full pressure to pull it back up and out the vent pipe. It actually shot out and went about 10 feet over and landed on the roof. The residents were extremely happy to be able to use their facilities again without any worry of flooding.
