If the blockage is not too significant, force it out using a blow bag. This drain can be cleaned with a standard main snake, a water jet, or a blow bag. I prefer a standard main machine since it cleanses the pipe's interior, chops up any roots, and forces debris out. A jet will remove any sand and debris from the line by flushing the pipe with 2,500 pounds of water pressure and eliminating sludge and debris from the inner pipe walls. A blow bag is a tool that expands within a pipe until it locks in place and then forces water through the pipe. This device breaks through the clog but doesn't remove all the debris or scrape the pipe clean.
