Final answer:
Floor drains should connect to a trap that can be cleaned, to prevent sewer gases from entering the building. Devices in sink drains can speed water flow by reducing trapped air. Chemical drain cleaners clear clogs, with alkaline types usually safer for home use than acidic ones.
Step-by-step explanation:
Floor drains are designed to quickly and efficiently remove water from floor areas, typically in industrial or commercial settings, but also in residential basements or garages. They should connect to a trap, which is an essential plumbing component that prevents sewer gases from entering the building. The trap does this by holding a small amount of water at all times, effectively sealing the drain. For proper maintenance and to ensure functionality, traps must be constructed in a way that they can be cleaned.
Sink drains may include devices designed to enhance the flow of water. These devices work on the principle of reducing the amount of air trapped in the plumbing, which can slow water movement. By allowing air to escape, or by directing water smoothly through the pipes, these devices help water to drain more quickly and efficiently.
Chemical drain cleaners are another method used to maintain drain speed by dissolving clogs that can impede water flow. Alkaline drain cleaners are often available in both solid and liquid forms and are generally safer for home use. Acidic drain cleaners, typically in liquid form, may require professional handling due to their corrosive nature and potential health hazards. These cleaners work by chemically reacting with the material causing the blockage, breaking it down to clear the passageway.
