How often should loop pumps that move water from the holding tank to the distribution loop be run?

The correct answer is that loop pumps should be run continuously. This is important because continuous operation of the loop pumps helps to maintain a consistent flow of water from the holding tank to the distribution loop, ensuring that the water is adequately circulated throughout the system. Continuous operation also assists in maintaining water quality by preventing stagnation and minimizing the risk of bacterial growth in the water supply. Stagnant water can lead to a variety of issues, including contamination and reduced efficacy of the dialysis process.

Moreover, operating the pumps continuously ensures that the water temperature remains consistent and that any potential contaminants are continuously circulated and filtered out, providing safer and higher-quality water for the patient treatments.

Options like running the pumps only during peak hours or intermittently could lead to insufficient water circulation, which in turn can impact water quality and availability. Running the pumps “as needed” could also create unpredictable conditions in the distribution loop and increase the risk of water quality issues. Thus, continuous operation is essential for the reliable and safe functioning of the water treatment system in a clinical setting.
