 Plumbing traps might look simple, but they do a lot of heavy lifting in keeping buildings safe, clean and odor free. A quick refresher on the ones you’ll see most often:

P Trap
Found under washbasins and sinks. It holds a small amount of water that blocks sewer gases from coming back into the room.
S Trap
Used in floor mounted toilets. Its curved path connects directly to the floor drain.
U Trap
A basic U-shaped seal that maintains a water barrier. Common in bathrooms and basin setups.
Bottle Trap
Seen under wall hung washbasins. It’s easy to clean and keeps the area looking tidy.
Grease Trap
A must in commercial kitchens. It captures oils and grease before they enter the drainage system.
Gully Trap
Placed outside buildings. It collects wastewater from kitchens and bathrooms before it goes to the main drain.
Interceptor Trap
Used in industrial or commercial sites. It separates heavy solids, grease or chemicals to protect downstream systems.
Understanding the right trap for the right fixture helps improve hygiene, reduce blockages and keep maintenance costs down. A small detail with a big impact.
