Use strainers for your Sinks, Tubs, and Showers, it's more important to use than you think.
The strainer will catch hair, soap chips, and other debris, before it falls in to your drain, and with time cause slow draining and eventually the unexpected clog. Remember to clean your strainers regularly too. You can buy the strainers at your local home store. It's way less expensive than calling a professional plumber.
