Is RootX® something I can flush down my toilet or is that something Roto-Rooter or a professional should handle?

We recommend hiring a professional to apply RootX. However, you can do it yourself, but please read the instructions carefully before using. Putting drain cleaning products down the toilet can cause additional problems if not done carefully. This product works best when applied through a sewer clean-out port with the water running. A two pound container only provides effective drain care for the first 50 feet of a 4-inch sewer main.
