For centuries, cast iron pipe and fittings have been the backbone of drain, waste and vent (DMV) plumbing systems throughout the world. As building codes have gradually given away to increasing use of PVC in both residential and commercial applications, plumbing engineers and contractors should remember that what is allowed by code may not necessarily provide the best solution. In fact, from a liability standpoint, maintaining the original specification and avoiding substitutions can be critical.


Charlotte Pipe manufactures PVC, ABS, ChemDrain®, FlowGuard Gold® and irrigation pipe and fittings. With hundreds of thousands of square feet of yard and modern warehouse space that is stocked with inventory, along with investments in the latest tooling and machinery, make it possible to meet increasing demand for products and to produce high-quality pipe and fittings in the industry.
