- 1901 - Recognizing the need for plumbing pipe in the newly industrialized, post-war South, W. Frank Dowd built a small foundry in Charlotte, North Carolina, to produce cast iron soil pipe and fittings. The original Charlotte Pipe and Foundry employed 25 men.
- 1926 - W. Frank Dowd's son, Frank Dowd II, began leading Charlotte Pipe with the goals of expanding the sales territory and developing stronger customer relationships.
- Early 1950s - Frank II's sons, Frank Dowd Jr. and Roddey Dowd joined the company. They supervised the overall mechanization of foundry production processes during a time when many cast iron pipe foundries ceased to operate due to relentless competition in the industry.
- Mid 1960s - Frank Dowd Jr. and Roddey Dowd directed the opening of the Plastics Division in 1967 in Monroe, North Carolina, to produce thermoplastic plumbing pipe and fittings for drain, waste and vent (DWV) applications.
- 1992 - Charlotte Pipe established the Industrial Plastics Division to supply Schedule 80 pipe and fittings manufactured from both PVC and CPVC resins for industrial applications.
- 1996 - The Plastics Division began producing FlowGuard Gold® pipe and fittings for hot and cold water distribution systems.
- 2005 - Charlotte Pipe began to produce and market the ChemDrain® line of pipe and fitting for chemical waste applications.
- 2009 - Charlotte Pipe began to produce and market ReUze®, CPVC pipe for non-potable indoor water applications.
- 2010 - Charlotte Pipe began to produce and market RePVC®, the first PVC DWV pipe that uses recycled content.
- Today - Charlotte Pipe is the largest manufacturer of DWV pipe and fittings in the United States and operates one of the largest fittings molding facilities in the world.
- The Company now has satellite pipe extrusion plants in Muncy, Pennsylvania; Cameron, Texas; Wildwood, Florida; Cedar City, UT; and Huntsville, Alabama.
- The facility at Monroe is still the Company's largest plastics pipe and fittings manufacturing operation, comprising more than 1,000,000 sq. ft. for extrusion and molding, and warehouse capacity of 625,000 sq. ft.
