Sourcing sewer branch 3/4" x 1/2" 5R (C30500Q35) copper alloy fitting

Sourcing sewer branch 3/4" x 1/2" 5R (C30500Q35) copper alloy fitting is a compact plumbing component designed to create a reliable branch connection between 3/4-inch and 1/2-inch sewer pipes. Manufactured from a copper alloy, this fitting provides mechanical strength, corrosion resistance and a stable junction for drainage systems. It is intended for use where a main sewer line requires a secondary tap or where pipe size reduction is needed for fixtures or repair work.

Advantages

The copper alloy construction offers good resistance to corrosion and long-term dimensional stability in typical residential and light commercial drainage environments. Its standardized sizing ensures compatibility with common 3/4" and 1/2" sewer pipe fittings, reducing installation complexity. The part is engineered to provide a leak-minimizing connection when properly joined and sealed according to accepted plumbing practices.

Suitable for

• Creating a branch from a 3/4" sewer line to a 1/2" branch line
• Repairing or modifying residential drainage systems
• Small commercial drainage and light renovation projects
• Tapping a main waste pipe to serve an additional fixture

Key specifications

• Material: copper alloy
• Connection sizes: 3/4" inlet, 1/2" outlet
• Type: sewer branch fitting (5R geometry)
• Intended use: drainage/sewer applications
• Typical joining methods: soldering, brazing, or approved mechanical seals depending on installation requirements

How to use

Prepare pipe ends by cleaning and deburring to ensure a proper fit. Position the fitting between the 3/4" and 1/2" pipes and join using the appropriate method for the site — solder or braze joints where permitted, or install with approved mechanical seals or adapters if required by the system. Verify alignment and slope for correct drainage, then test the connection for leaks after installation. Follow local plumbing codes and manufacturer recommendations for sealing, support, and ventilation.

Usage recommendations

Use appropriate fluxes and solder alloys compatible with copper alloys when making soldered joints, and allow adequate cooling and inspection time. For installations in corrosive environments or where dissimilar metals are present, apply suitable corrosion protection and use dielectric fittings or isolation methods as required by code.
