Question: How To Install A Kitchen Sink S-pipe?

Why are S traps bad?

But why is the S trap illegal? The ā€œSā€ trap is prohibited under the Uniform Plumbing Code throughout the United States. This is because the ā€œSā€ trap will siphon or suck water out from the trap which will end up releasing methane (sewer) gases into the home.
