Is it better to install a plastic or metal P trap? Is it better to install a plastic or metal P trap?
If you're looking for durability in a P trap that needs replacing, you will find that one made of plastic is generally more durable than a metal one. The exception may be a metal P trap made of heavy gauge brass. When it comes to replacing a P trap in your bathroom or kitchen, making the wrong choice may result in your having to replace the new P trap again, sooner than you would like.
