1.25″P-Trap

a plumbing component used in drainage systems, specifically in sinks, showers, and other fixtures. Let’s break down the term:

1. 1.25″: This refers to the diameter of the P-Trap’s pipe, measured in inches. In this case, it indicates that the P-Trap has a pipe with a diameter of 1.25 inches. Pipe diameter is crucial for ensuring proper drainage and preventing clogs.
2. P-Trap: A P-Trap is a type of plumbing trap that is commonly used in household drainage systems. It is named for its shape, which resembles the letter “P” when viewed from the side. The purpose of a P-Trap is to prevent sewer gases from entering the building while allowing wastewater to flow freely. It does this by trapping a small amount of water in the bend of the trap, which forms a seal against the gases.

So, a “1.25” P-Trap is a specific type of P-Trap with a pipe diameter of 1.25 inches. It’s commonly used in residential and commercial plumbing applications, particularly in sinks and other fixtures where space is limited.
