A drain cleanout is positioned outside your home in the front or back yard and offers access to your main sewage line. Typically, cleanouts go unnoticed until there is a problem. They resemble capped pipes that protrude a few inches from the ground. Installing cleanout drainpipes make unclogging clogged pipes a lot easier. It also makes detecting problems in your drain line, which connects your home to the sewer or septic tank, much more accessible. You'll understand precisely what's wrong and how to avoid it in the future.
