About Plumbing Pipes

Plumbing pipes are the foundation of every water supply, heating, and drainage system. Whether you're installing new water lines, replacing aging pipes, or upgrading an existing plumbing system, choosing the right pipe material and size is essential for reliable performance. At PlumbingSell, we offer a selection of plumbing pipes and tubing for residential and commercial projects, including PEX, copper, and CPVC options.

Types of Plumbing Pipes We Offer

Different plumbing pipe materials are designed for specific applications, from hot and cold water distribution to drainage and hydronic heating. Understanding their properties, connection methods, and installation requirements can help you choose the right solution.

PEX Pipe

PEX pipe is a popular choice for modern residential plumbing thanks to its flexibility, corrosion resistance, and ease of installation. Available in common sizes such as 1/2", 3/4", and 1", PEX tubing is widely used for hot and cold water supply lines, home renovations, and approved heating applications.

PEX-A vs. PEX-B: Both types offer dependable performance when properly installed, but they differ in flexibility and common connection methods. PEX-A tubing is known for its flexibility and is commonly used with expansion fittings, while PEX-B tubing is frequently paired with crimp or clamp connection systems. Always verify tubing and fitting compatibility before installation.

For radiant floor heating and certain closed-loop hydronic systems, oxygen barrier PEX tubing helps limit oxygen diffusion into the circulating water, protecting compatible metal components from oxygen-related corrosion.

Copper Pipe

Copper pipes have been widely used in plumbing for decades because of their durability, heat resistance, and long service life. Commonly available in Type K, L, and M, copper tubing is suitable for a range of water supply applications when the correct type and specifications are selected.

For new installations and pipe replacements, explore our straight copper pipes to find compatible tubing for your project. Copper lines can also be connected to PEX using properly rated transition fittings, making it possible to combine different piping materials during renovations.

PVC Pipe

PVC pipes are commonly used in drain, waste, and vent (DWV) systems, as well as approved cold-water pressure applications. Their lightweight construction, corrosion resistance, and affordability make them a practical choice for residential drainage and other compatible plumbing projects.

PVC Schedule 40 and Schedule 80 pipes are available for different installation requirements. Always distinguish pressure-rated PVC from DWV-only piping, and confirm the pipe's temperature limits and approved applications before use.

CPVC Pipe

CPVC pipes are designed for approved hot and cold water distribution systems. Compared with standard PVC, CPVC offers higher temperature resistance and is commonly used in residential water supply installations. Browse our CPVC pipes for compatible plumbing applications, and verify the required pipe dimensions, fittings, and joining method.

Choosing the Right Pipe Size

Selecting the correct plumbing pipe size helps maintain appropriate water flow and pressure throughout the system. Pipe sizing depends on the material, nominal dimensions, and applicable standards, so always confirm the actual pipe dimensions and fitting compatibility.

• 1/2" PEX Pipe: Commonly used for residential fixture branches supplying sinks, toilets, and other individual fixtures.
• 3/4" PEX Pipe: Often selected for larger branch lines and residential water distribution where greater flow capacity is required.
• 1" PEX Pipe: Suitable for larger distribution lines and higher-demand plumbing systems when supported by the system design.

When replacing existing plumbing pipes, check the nominal size, outside diameter, pipe material, and connection requirements. Correct sizing helps prevent fitting mismatches and supports proper system performance.

Tools for Easy Installation

Proper installation requires more than selecting the right pipes. Using compatible tools and fittings is essential for creating secure connections and reducing installation errors.

• PEX Crimp Tools: Used with compatible crimp fittings and rings to create secure connections in approved PEX systems.
• PEX Expansion Tools: Designed to expand compatible PEX-A tubing and expansion rings before inserting ASTM F1960 fittings.
• PEX Pipe Cutters: Create clean, square cuts that help ensure proper fitting insertion and connection quality.
• Copper Pipe Cutters: Provide accurate cuts for copper tubing installations and plumbing repairs.

Always follow the manufacturer's installation instructions, including pipe preparation, fitting insertion depth, and tool requirements. Matching the connection method to the tubing type is essential for reliable plumbing performance.
