Water Line Replacement for Older Homes in Charleston
Much of the housing in South Carolina was built after 1970, so copper, CPVC and PEX supply lines are far more common than old galvanized pipe. Many older homes still have galvanized steel or aging copper pipes that are prone to corrosion, leaks and reduced water pressure. KBN Plumbing provides professional water line replacement in Charleston, upgrading your system to modern, durable materials like PEX or new copper. This boosts water quality and pressure and prevents costly future repairs caused by failing pipes.

PEX and HDPE Water Line Installation in Charleston, SC
PEX and HDPE are flexible, which means fewer fittings in the ground and better tolerance for soil movement. HDPE is especially durable for long runs and holds up against cracking in expansive clay. We use approved compression or fusion fittings and add tracer wire so the line can be found with a locator later. PEX must stay out of sunlight before burial, so we store and lay it carefully on every job site.
