Quick Answer
To adjust filtration systems for low water pressure, check the filter's micron rating, reduce the flow rate, or upgrade the filter to a lower micron rating with a higher flow rate.
Assessing the Filter’s Micron Rating
A whole-house filtration system’s micron rating determines its effectiveness in removing contaminants. A lower micron rating (e.g., 1-5 microns) may restrict water flow, leading to low pressure. Consider upgrading to a filter with a higher micron rating (e.g., 10-20 microns) for improved flow rates. A good starting point is to check the filter’s manufacturer recommendation for optimal flow rates.
Reducing the Flow Rate
To mitigate low water pressure, reduce the flow rate by installing a flow restrictor or an adjustable flow control valve. The typical flow rate for a whole-house filtration system is 10-15 gallons per minute (GPM). For low-pressure applications, reduce the flow rate to 5-7 GPM. This will help distribute the water pressure more evenly throughout the household.
Upgrading the Filter
Consider upgrading to a filter with a higher flow rate, such as a high-flow sediment filter or a UV filter. These filters typically have flow rates of 10-20 GPM, providing a more consistent water pressure. Additionally, some whole-house filtration systems come with adjustable flow control valves that allow for easier adjustments to meet specific pressure requirements.
