Showers usually experience hair clogs. This is especially true if the people using the shower have long hair. Keep the shower drain free of hair by placing a hair trap over the shower drain. Clear hair out of the shower drain by using a zip stick or by bending a quarter inche hook into the end of a wire coat hanger. Push the hook into the drain as deep as it will go. Twist it around and slowly pull out the hair balls. This works best if the drain is wet. Repeat the process until no more hair is in the drain. Finally, treat your drain monthly with a safe, bio-based drain maintenance liquid like Roto-Rooter Pipe Shield.
