A sewer cleanout is a pipe that gives you access to your home's sewer line. So, it's critical for maintaining your connection to your sewer system. Should a backup occur, getting to a sewer cleanout quickly can save you money and reduce the damage from an overflow inside your house. To make sure they are easily accessible, sometimes a builder will install a sewer cleanout above grade. Sometimes that's because of a local law on how high above ground a sewer cleanout has to be. But a sewer cleanout that is above ground has its own set of problems. Luckily, I've found a pretty easy and cheap solution.
