Copper Float Ball for Liquid Level Control

The Watts C5 is a copper float ball designed for internal connection in automatic watering kits, stems and nozzle assemblies. Its 5 inch diameter and 1/4-20 thread size allow direct attachment to compatible valve mechanisms. The unit is rated for liquid temperatures up to 200 degrees F.

Suited for High-Temperature Water Systems

This float suits installers maintaining livestock waterers, cisterns or industrial tanks where liquid temperatures approach 200 degrees F. Its copper construction and 0.17 specific gravity provide reliable buoyancy in hot water. Builders needing a larger displacement volume or a different thread standard should look at alternative float designs.

Integrates With Valve Stems and Nozzle Assemblies

The 1/4-20 thread mates with standard valve stems used in automatic watering kits, freeing the installer from fabricating custom brackets. Weighing 0.81 ounces, the ball adds minimal load to the lever arm. No external power or control wiring is required for the float itself.

Questions about this item

What thread size does the Watts C5 Float Ball need on my existing stem or nozzle assembly?

The float ball has an internal 1/4 in.-20 thread that screws onto a matching stem or nozzle assembly.

Will the 0.81 oz copper float still operate correctly if my tank runs at the 200 °F maximum liquid temperature?

Yes, the float is rated for liquids up to 200 °F and its 0.17 specific gravity keeps it buoyant at that temperature.

How can I confirm the float ball is seated and moving freely after I install it?

Watch the float rise and fall smoothly through its full travel without binding, and verify the water level stops at the expected point.
