Ao Smith 100264226 Dip Tube Kit Water Heater

Product Description

The AO SMITH 100264226 is a dip tube replacement kit designed for residential and light commercial water heaters. The dip tube directs incoming cold water to the bottom of the tank, keeping it separated from the hot water at the top and maintaining efficient heat transfer throughout the tank. This kit measures 0.65 inches in diameter and 34 inches in length, with a 3-inch x 3/4 NPT connection fitting. It is installed by licensed plumbers during routine maintenance or when a failed dip tube causes complaints of lukewarm water or plastic debris in the hot water supply.

This dip tube kit is suited for water heater applications where the cold water inlet assembly requires replacement. The 3/4 NPT threaded connection is a standard size found on many residential tank-style water heaters. The 34-inch length is typical for taller tank configurations. Plumbers and water heater service technicians install this part when diagnosing reduced hot water output or contamination traced to a degraded original dip tube.

Key Features

• 0.65-inch diameter tube directs cold inlet water to the bottom of the tank
• 34-inch length suits taller residential water heater tanks
• 3/4 NPT threaded connection for standard cold inlet port fitment
• 3-inch fitting dimension for proper inlet assembly seating
• Complete kit format simplifies replacement during service calls

Compatibility

Designed as an OEM-style replacement dip tube kit for tank-style water heaters with a standard 3/4 NPT cold water inlet connection.

Installation Notes

Dip tube replacement is performed by a licensed plumber. Before beginning, shut off the cold water supply and disconnect power or turn off the gas supply to the water heater to prevent heating during service. Drain a sufficient amount of water from the tank before removing the old dip tube to reduce pressure at the inlet port. Follow all applicable local plumbing codes and manufacturer guidelines when reassembling the inlet connection.
