The answer to 'drain trap maintenance' is to regularly clean and inspect your drain traps to prevent clogs and ensure proper drainage. Drain traps are the curved pipe section under sinks, tubs, and floor drains that hold a small amount of water to prevent sewer gases from entering your home.
It's recommended to check and clean your drain traps every 6-12 months, or if you notice slow draining or foul odors. To clean, simply remove the trap, flush it with water, and use a flexible wire or drain snake to clear any buildup. Be sure to wear gloves and eye protection, and work slowly to avoid splashing. If the trap is severely clogged or damaged, you may need to replace it, which is a job best left to a professional plumber.
