How Do I Unclog Drain Pipe that is Outside My House?
I have an outdoor water drain that has piping that leads under the house. The drain is clogged so deep that it looks like the piping under the house is also clogged. How can I unclog this pipe/drain?
This type of drain can be cleaned with a typical main snake, a water jetter, or if the clog is not too big, you may be able to force it out with a blow bag. A normal main machine would be my choice, because it pushes the debris out of the pipe, chops up any roots and scrapes the inside of the pipe clean. A jetter will clean any sand and debris out of the pipe by using 2,500 pounds of water pressure to flush the pipe, removing sludge and debris from the inside pipe walls. A blow bag is a device that expands in the pipe until it locks in place, then fills the pipe with water pressure. This device breaks through the clog, but doesn't remove all of the debris or scrape the pipe clean.
