What is Plumbing Reducers?
Plumbing reducers are fittings that connect pipes of different sizes, creating a smoother transition between smaller and larger pipes.
Definition
Purpose
Plumbing reducers create a reliable connection between pipes with different diameters. This makes it easier to connect different sections of a water supply, drainage, or other piping system without using an improvised connection.
Examples of Use
- A plumber may use a reducer to connect a 1-inch water supply pipe to a ¾-inch branch line serving a sink.
- In a larger system, reducers can also be used where pipe sizes change between different sections of the distribution network.

Notes
- Available in concentric and eccentric designs.
- Can be made for threaded, soldered, press-fit, and other connection methods.
- Helps create a clean transition between different pipe sizes.
- A plumbing reducer is different from a plumbing pressure reducer. A pipe reducer changes pipe diameter, while a plumbing pressure reducing valve changes water pressure.
