There is a thing called a rubber bladder u can buy at home depot for cheap, it's really good at clearing clogs. You attach it to a hose put in into ur pipe, when u turn the hose on it swells to the size of ur pipe so water can't go backwards. The water is forced forward with increasing pressure and clears the clog.
