Copper Reducing Tee for Drain Lines

The Nibco C611 is a copper reducing tee designed for drain and trap assemblies. Its tee configuration joins a 1-1/2 inch run with a 1 inch branch, making it suitable for plumbing transitions in residential and light commercial systems. Copper construction avoids leaching toxins into water or gases.

Thermal Noise and Power Characteristics

As a passive copper fitting, the component generates no heat, produces no noise and draws no power during normal operation. It relies on the surrounding piping system for structural support and does not introduce any thermal load or acoustic signature to the installation.

Build Integration and System Fit

The fitting requires compatible 1-1/2 inch and 1 inch copper tubing plus solder or press tools for a watertight joint. It frees the installer from needing dissimilar-metal adapters at the reduction point, simplifying the material list for drain renovations or new rough-ins.

Questions about this item

How is the C611 reducing tee installed and what step is often missed?

The C611 reducing tee is soldered into copper piping using flux and lead-free solder; the step often missed is thoroughly cleaning and fluxing both the fitting sockets and tube ends before heating.

What maintenance or replacement will the C611 reducing tee need later?

Copper fittings like the C611 rarely need replacement; periodic visual inspection for green corrosion or joint weeping is the only maintenance typically required.

What limit appears first on the C611 reducing tee under sustained use?

The 1.5-inch run and 1-inch outlet set the flow capacity limit; sustained high velocity can accelerate erosion at the reducing transition.
