The AO SMITH 100269117 is a brass ball drain valve kit designed for use in water heater service and maintenance applications. The kit includes 10 ball-style drain valves constructed from brass, providing durable shutoff capability at the tank drain port. Each valve measures 3 inches and is suited for installation by licensed plumbers and water heater service technicians. The brass construction resists corrosion in water heater drain environments, making this kit a practical supply to keep on hand for multiple service calls or installations.
This drain valve kit is intended for water heater applications where a reliable ball valve drain is required. The 10-piece quantity makes it appropriate for wholesale stocking, multi-unit residential projects, or service fleets that replace drain valves routinely during water heater installation or maintenance. It is compatible with standard water heater drain port connections where a ball-style valve is preferred over a gate-style valve for positive shutoff performance.
Designed as an OEM-style replacement drain valve for AO SMITH water heaters requiring a brass ball-style drain valve at the tank drain port.
Installation should be performed by a licensed plumber following applicable local plumbing codes and IPC guidelines. Before replacing a drain valve, shut off the cold water supply and power or gas to the water heater, and allow the tank to cool. Thread the valve into the drain port by hand first to avoid cross-threading, then snug with appropriate hand tools. Do not overtighten brass fittings, as brass threads can be damaged by excessive torque.
