CPVC Plastic Pipe, 3/4 100 Psi

Step up to 3/4-inch CPVC plastic pipe when your water-treatment or plumbing project needs more flow than a half-inch line can comfortably deliver. The larger interior bore is a common choice for main supply runs feeding water softeners, sediment filters, carbon tanks, and whole-house treatment equipment in both homes and light commercial settings. By keeping flow strong to and from your equipment, the right pipe size helps your treatment system perform as designed without creating a bottleneck that starves downstream fixtures of pressure and volume.

Manufactured from chlorinated polyvinyl chloride and rated at 100 psi, this pipe shrugs off the corrosion and mineral scaling that shorten the life of metal alternatives. It is offered in 10-foot lengths only, which is ideal for spanning longer distances with fewer couplings and producing a cleaner, more professional finished installation. Because CPVC handles both hot and cold water without softening or degrading, it works equally well on supply lines throughout the house, from the main inlet to the water heater and beyond.

• 3/4-inch nominal size for higher-demand supply and treatment lines
• 100 psi pressure rating suited to standard residential water pressures
• Packaged exclusively in convenient 10-foot lengths
• Joins quickly with solvent cement and standard CPVC fittings
• Handles both hot and cold water without warping or breaking down
• Resistant to rust, scale buildup, and many common waterborne chemicals

Installation Notes

CPVC's smooth interior wall keeps flow rates high and operating noise low, while its inherent chemical resistance makes it a sound companion to softeners and filtration gear that contact both treated and untreated water. The material is lightweight, which speeds up handling and reduces installer fatigue on larger jobs, and it cuts cleanly to length with simple tools. For best results, measure and cut accurately, remove all burrs from the cut ends so they do not interfere with flow or seating, dry-fit the run before bonding to confirm alignment, then apply primer and cement per the product directions and allow the full recommended cure time before restoring pressure to the system. Patient, methodical assembly is what produces a long-lasting, drip-free 3/4-inch water line that supports your treatment equipment for many years.
