A discharge pipe is a pipe that carries fluids away from equipment, fixtures, or systems to a designated outlet or drainage point.

A discharge pipe is a piping component used to convey fluids away from equipment, fixtures, or mechanical systems after operation. It directs water, air, or other fluids from a source to a designated outlet, drain, or disposal location.

In construction and building systems, discharge pipes are commonly associated with sump pumps, water heaters, HVAC condensate systems, relief valves, and drainage equipment. Materials vary by application and may include PVC, CPVC, copper, steel, or flexible tubing, selected based on temperature, pressure, and code requirements.

From a safety and performance standpoint, proper installation of discharge pipes is critical to prevent leaks, flooding, backflow, or system failure. Codes often regulate discharge pipe size, routing, termination points, and freeze protection. Correct slope, secure connections, and approved termination locations help ensure reliable operation and long-term durability.

Sump pump discharge pipes are often routed far from foundations—sometimes underground—to keep water from flowing right back toward the building.
