Plumbing TermP-Trap
/pee-trap/
A curved pipe section that holds water to block sewer gases from entering through drains.
Full Definition
A P-trap is a curved, P-shaped pipe section located beneath sinks, tubs, and other fixtures that holds water to create a seal preventing sewer gases from entering your home.
Common Usage
“Found under every sink in your home, the P-trap is the curved pipe you see when you open cabinet doors beneath the basin.”
Did You Know?
The water sitting in your P-trap evaporates over time if a fixture isn't used regularly, which can lead to sewer gas smells.
