Ever notice a foul sewer smell under your kitchen sink or bathroom sink that keeps coming back even though there are no leaks or clogs?

Learn how plumbing traps work, the critical difference between a P-trap and an S-trap, why S-traps were banned by modern plumbing codes, how trap siphoning destroys your water seal, and what allows sewer gas, hydrogen sulfide, methane, drain flies, and pests to enter your home.
