The Rheem-Ruddc RTG20239N Neutralization Kit, model number 31-98252-00, is an essential accessory for maintaining the optimal performance of your Rheem or Ruud brand tankless water heater. This kit is specifically designed for use with the RTG-Series tankless water heaters, ensuring a perfect fit and effective functionality.
The neutralization kit includes three important components: a pre-filter, a neutralizer, and a post-filter. These components work together to extend the life of your water heater by mitigating the damaging effects of hard water and mineral buildup.
The pre-filter is designed to remove large particles, sediment, and debris from the water supply before it enters the water heater. This helps to prevent clogging and prolongs the life of the water heater and its internal components.
The neutralizer is the core component of the neutralization kit. It is formulated with a unique blend of chemicals that neutralizes the acidic or alkaline water conditions, preventing the formation of scale and mineral buildup on the heat exchanger. This not only ensures the water heater operates efficiently but also minimizes the need for frequent maintenance and extends the overall lifespan of the unit.
The post-filter is the final component in the neutralization process. It effectively removes any remaining small particles or contaminants that may have passed through the pre-filter. This ensures the water that enters your appliances and fixtures is clean and free from impurities, enhancing the overall water quality in your home.
In summary, the Rheem-Ruddc RTG20239N Neutralization Kit is an essential accessory for maintaining the optimal performance and longevity of your RTG-Series tankless water heater. With its pre-filter, neutralizer, and post-filter components, this kit effectively addresses the challenges posed by hard water and mineral buildup, ensuring your water heater operates efficiently and reliably for years to come.
