The answer to 'drain trap replacement frequency' is that drain traps should generally be replaced every 3-5 years, or sooner if they become cracked, damaged, or clogged. Drain traps are the curved section of pipe under a sink or tub that helps prevent sewer gases from entering the home. Over time, they can deteriorate, leading to leaks or blockages. Replacing the drain trap on a regular schedule helps ensure your plumbing system continues to function properly and prevent any water damage.
Homeowners should regularly inspect their drain traps and consider replacing them if they notice any issues. It's a relatively simple and inexpensive DIY project, but if you're uncomfortable working on your plumbing, it's best to call in a professional plumber to handle the replacement.
