Watts 780011 Float Valve 1 Inch

Product Description

The WATTS 780011 is a 1-inch float valve designed to automatically regulate fluid levels in tanks, reservoirs, and storage vessels. As water or fluid rises to a set level, the float actuates the valve to shut off flow, then reopens as the level drops. This type of mechanical level control is a standard solution in plumbing, agricultural, and commercial water management applications. The 780011 weighs 1.9 pounds and fits a 1-inch connection. Licensed plumbers and water system technicians are the typical installers for this component.

Float valves in this size range are commonly used in potable water storage tanks, livestock watering troughs, cooling tower makeup lines, pressure tanks, and similar installations where passive, automatic level control is required. The 1-inch port size handles moderate flow rates suitable for residential and light commercial setups. This valve provides reliable fill and shutoff without the need for electrical controls or external power.

Key Features

• 1-inch connection size for moderate-flow level control applications
• Mechanical float-actuated operation requires no electrical power
• Automatic shutoff when fluid reaches set level, reopens as level drops
• Compact and lightweight at 1.9 pounds for straightforward installation
• Suitable for tanks, reservoirs, and makeup water applications

Compatibility

Designed as an OEM-style replacement or direct-install float valve for 1-inch ported tanks, reservoirs, and fluid storage systems requiring passive level control.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before removing or installing the valve. Use appropriate thread sealant or PTFE tape on threaded connections and verify the float arm is positioned correctly for the desired shutoff level. Do not overtighten fittings, as damage to the valve body may result.
