A Small But Essential Component

What is a Trap?
Draining sewage and waste out of your home or office can get smelly. That's because fumes from gases like methane, nitrogen, hydrogen sulfide and carbon monoxide are a by-product of wastes. The job of a plumbing trap is to keep these gases (and their odors), and also small vermin, from entering your home or office via the drain pipes. How does a plumbing trap work? It works by creating a water seal by allowing a small amount of water to be retained in the trap and not allowing anything back up through the pipe. All plumbing fixtures, sinks, toilets, tubs, showers, utility sinks, washer drains, etc. have a trap of some kind.
