Ao Smith 100217961 Dip Tube Diffuser Kit 40 in

Product Description

The AO SMITH 100217961 is a dip tube diffuser kit designed for use in water heater applications as an OEM-style replacement component. The dip tube extends into the water heater tank to direct cold inlet water to the bottom of the tank, improving heating efficiency by reducing mixing with hot water at the top. This kit measures 40 inches in length with a 3/4 inch by 3 inch fitting size. It is a direct replacement part intended for installation by licensed plumbers or qualified water heater service technicians.

This dip tube diffuser kit is suited for residential water heater installations where the original dip tube has failed, corroded, or fragmented. A deteriorated dip tube is a common cause of reduced hot water output and sediment in the system. Replacing the dip tube restores proper cold-water stratification inside the tank and returns the unit to normal operating performance.

Key Features

• 40-inch length fits standard residential water heater tank configurations
• 3/4 inch by 3 inch fitting size for compatible cold inlet connections
• OEM-style replacement restores original tank thermal stratification performance
• Direct replacement design simplifies installation with minimal modification

Compatibility

Designed as an OEM-style replacement dip tube diffuser kit for compatible AO SMITH water heater models. Verify inlet port size and tank configuration before installation.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater technician. Before beginning, shut off the cold water supply and disconnect power or turn off the gas supply to the water heater to allow the tank to cool. The dip tube is inserted into the cold water inlet port and should be secured per the manufacturer connection requirements. Consult local plumbing codes, including the IPC, for applicable guidelines.
