1. Stay aware of what you pour down your sinks
There are certain common culprits of drain clogs. Just because something can go down your drain doesn't mean it should. You can prevent massive clogs simply by dumping solid and greasy wastes in your trash instead of forcing them into your drains. Remember that your drain is made of a material that doesn't easily allow sticky stuff to slip. So, save yourself the trouble by dumping sticky stuff in the trash.
2. Flush all your drains regularly
Yet another way to unclog drains is by sending a forceful blast of water to clear out whatever has been accumulated there. Hair and debris tend to clog up a drain over time when it isn't tended to regularly. By flushing your drains regularly, you can make sure that nothing sticks and whatever sticks is cleared off before it starts-off a larger problem.
3. Use natural, homemade solutions
When your drain is clogged, there can be different degrees of clogging. If the drain isn't clogged beyond rescue, you can treat it with simple, homemade solutions. Instead of relying on chemicals, try sending a blast of hot water down your drain. Alternatively, you could also pour a cup of bleach down the drain or the combination of a ¾ cup of baking soda and ½ cup vinegar. This usually does the trick.
