Lochinvar & A.O. Smith 100217961 Diptube
For professional contractors servicing Lochinvar and A.O. Smith systems, the Lochinvar & A.O. Smith 100217961 Diptube is the high-performance OEM replacement part required to restore thermal efficiency and prevent sediment buildup. This 40-inch diffuser diptube features a 3/4" x 3" connection, specifically engineered to direct cold water to the bottom of the heater tank. By utilizing a diffuser kit design, it prevents the turbulence that can disrupt temperature stacking, ensuring a consistent supply of hot water and mitigating the "handover" effect where water temperature drops prematurely. As a genuine replacement part, it meets the exact factory tolerances of A.O. Smith water heaters and Lochinvar equipment, eliminating the risk of bypass or poor fitment associated with universal aftermarket alternatives. Built for high-temperature resilience, this hot water heater dip tube is a critical component for maintaining peak energy savings and equipment longevity in both residential and light commercial applications.
Key Benefits for Technicians:- Factory-Correct 40” Length: Ensures cold water delivery reaches the optimal heating zone at the base of the tank.
- Enhanced Diffuser Design: Minimizes cold-water mixing in the upper tank sections to maintain high delivery ratings.
- Universal Brand Compatibility: Cross-references directly for multiple 100217961 and 9008992005 configurations.
- Rugged Construction: Engineered to withstand thermal cycling and high-pressure environments without warping.
What is the purpose of the diffuser on the end of the 100217961 diptube?
The diffuser head breaks up the incoming cold water stream to prevent it from stirring up sediment at the bottom of the tank and to keep cold water from mixing directly with the hot water at the top, which preserves the heater's efficiency.
Can I trim this 40-inch diptube to fit shorter tanks?
Yes, contractors often trim diptubes to fit specific tank heights, but it is critical to maintain the integrity of the diffuser end to ensure proper water distribution inside the vessel.
Is this a direct replacement for the 9008992005 part number?
Yes, the 100217961 is the current manufacturer part number that replaces the older 9008992005 model in Lochinvar and A.O. Smith technical catalogs.
