Ao Smith 100273983 Dip Tube Kit Water Heater Part

Product Description

The AO SMITH 100273983 is a dip tube kit designed for use in 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 stratification. This kit includes a 0.65-inch diameter tube at 52.5 inches in length, along with a 5.5-inch section with a 3/4-inch connection. It is installed by licensed plumbers or qualified HVAC-plumbing technicians during routine maintenance or water heater repair service.

This dip tube kit is suited for water heater applications where the original dip tube has degraded, broken, or caused sediment buildup in the tank. Dip tube failure is a common cause of inconsistent hot water delivery, and replacing it restores proper thermal layering inside the tank. The 52.5-inch length and 0.65-inch diameter make this kit appropriate for standard residential tank-style water heater configurations that accept a 3/4-inch inlet connection.

Key Features

• Tube diameter of 0.65 inches and length of 52.5 inches for deep cold-water delivery to tank bottom
• 3/4-inch connection size for compatibility with standard water heater cold inlet ports
• 5.5-inch upper section provides proper positioning at the inlet fitting
• Restores efficient heat stratification by separating incoming cold water from stored hot water
• Direct replacement kit format simplifies field service and reduces repair time

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician. Shut off the cold water supply and disconnect power or gas to the water heater before beginning service. Drain sufficient water from the tank to allow safe access to the inlet fitting before removing the old dip tube. Follow all applicable local plumbing codes and IPC guidelines during installation.
