A.o. Smith 100108853 Dip Tube Assembly 36 Inches

Product Description

The A.O. SMITH 100108853 is a 36-inch dip tube assembly that includes a diffuser and gasket, designed as a direct replacement component for water heater service. The dip tube directs incoming cold water to the bottom of the tank, keeping cold supply water separated from the hot water at the top and maintaining thermal efficiency throughout the storage cycle. Plumbers and water heater service technicians install this assembly during maintenance or when an existing dip tube has broken, cracked, or become brittle with age. The included diffuser and pre-fitted gasket simplify the replacement process.

This assembly is suited for residential and light-commercial storage water heater applications where the dip tube has failed or is suspected of shedding plastic fragments into the hot water supply. The 36-inch length is appropriate for standard tank-style water heaters that require that inlet tube depth. The integrated gasket provides a proper seal at the cold water inlet port to prevent cross-flow between the cold inlet and stored hot water.

Key Features

• 36-inch overall length sized for standard tank-style water heater installations
• Diffuser included to reduce turbulence at the cold water inlet and limit disruption of stratified hot water
• Pre-packaged gasket included for a complete, single-part replacement
• OEM-style replacement designed to restore original performance characteristics

Compatibility

Designed as an OEM-style replacement dip tube assembly for A.O. SMITH tank-style water heaters requiring a 36-inch dip tube with diffuser. Verify the inlet fitting size and tube length against the existing unit before installation.

Installation Notes

Installation is typically performed by a licensed plumber. Before servicing, shut off the cold water supply to the water heater and relieve system pressure. Drain the tank sufficiently to prevent backflow at the cold inlet port before removing the old dip tube. Torque the inlet fitting to the manufacturer specification shown on the unit label, and inspect the new gasket seating before restoring water supply and checking for leaks.
