Resideo 50033181-001 Water Tank
The Resideo 50033181-001 Large Water Tank is a direct replacement component for Honeywell TrueSTEAM humidifiers, specifically engineered to restore the pressure and steam output of failing units. This high-capacity reservoir assembly is essential for technicians servicing the HM506, HM509, HM512, HM609, and HM612 series. Manufactured for units produced in 2012 and later, this kit addresses common failure points such as mineral buildup, tank discoloration from high-temperature cycles, and chronic leakage at the base seal. The package includes the updated black polymer tank, which offers superior thermal resistance compared to older grey models, along with a integrated Spool Valve and a high-durometer neoprene gasket. A dedicated gasket removal tool is also included to ensure the sealing surface of the humidifier frame is completely cleared of old adhesive and debris, preventing future steam-pressure loss and ensuring a watertight fit in 24V steam humidification systems.
Key Benefits for HVAC Professionals- Broad Series Compatibility: Fits the entire TrueSTEAM HM series, including 6-gallon, 9-gallon, and 12-gallon residential steam humidifiers.
- Complete Service Kit: Includes the Resideo replacement tank, spool valve, and an o-ring style gasket that compresses more effectively than original foam seals.
- Sediment Management: The tank design facilitates easier maintenance of the internal sediment screen and heating element to maintain a 1:1 humidification delivery rate.
- Simplified Installation: Comes with a specialized gasket tool to prevent technicians from scratching the sealing channel with metal screwdrivers.
- Will this fit older TrueSTEAM units? This tank is designed for units manufactured from 2012 to the present. While the mounting bracket and solenoid location are consistent across generations, verify the manufacture date to ensure the depth and seal alignment match.
- How do I prevent calcium buildup in the new tank? For systems with high water hardness, it is recommended to pair this tank with an HM600XROF1/U reverse osmosis system or a polyphosphate filter to extend the service life of the humidifier water reservoir.
- Do I need to replace the water level sensor too? While not included in this kit, it is best practice to inspect and clean the sensor probes with an abrasive pad while the tank is removed for replacement.
