Maintain consistent boiler water levels and prevent low-water damage with the reliable 126400 McDonnell & Miller Model 21 make-up water feeder. This essential component is engineered to automatically replenish water supply in steam and hot water boilers, ensuring your hydronic system operates at optimal efficiency without the need for manual intervention.

The unit utilizes a precision-engineered float mechanism that monitors the fluid level within the boiler. When levels drop below the threshold, the valve assembly opens to introduce make-up water, closing automatically once the required set point is reached to prevent overfilling and potential pressure issues.

Key System Performance Baselines:

  • Automatic Regulation: Maintains consistent water line levels for peak boiler efficiency.
  • Robust Engineering: Designed for long-term durability in high-cycle hydronic environments.
  • Seamless Integration: Engineered to provide reliable mechanical fluid control across diverse boiler configurations.

⚠️ Application Profile: Recommended for use in residential and commercial steam or hot water heating boilers where automatic, mechanical level control is required for system safety and consistent pressure management.
