Here are some great tips to help you avoid clogs in your home's drains:
Clean the drain strainers. Some showers and tubs have strainers that are screwed into the drain opening. Unscrew them and use a wire to clear out built-up debris, which you may not always be able to see. Also, be sure to scour the strainer before replacing it. At a minimum, do this at least once per quarter.
Pop-up sink stoppers should be lifted out and rinsed weekly. When hair and soap accumulate, they will quickly slip down into the pipes.
Use a hair-catching drain insert, which can be found at hardware stores, plumbing supply houses, and even online. These catch most of the hair and other debris that lead to clogs without interfering with your drainage system.
Don't use your bathtub for major cleaning projects. While it might seem like a good idea to clean engine parts or other nasty things in the tub, you're actually washing more grease and other substances down the drain than it was designed to handle. Instead, use a wash tub that isn't connected to any drains to prevent clogging and other unwanted side effects.
Many people bathe their dogs in the bathtub because you can regulate the water temperature. Before bringing Fido into the tub, make sure to give him a good brushing first to remove loose hair, then use a hair-catching insert to keep fur from washing down the drain.
