Signs the Current Setup is Failing
Homeowners should be aware of several observable symptoms that indicate their 20-inch Big Blue filtration system may not be effectively removing contaminants. One common sign is a noticeable change in water clarity or color, which can suggest an accumulation of sediment or particulate matter that the filter is not capturing adequately. If you notice a yellowish or brown tint to your water, it may be time to assess your filtration system.
Another indicator of reduced performance is a decrease in water pressure at faucets and fixtures. If the flow rate diminishes, this might signal that the filter cartridges are clogged and require replacement. Additionally, an unusual or unpleasant taste or odor in the water can also point to filter inefficiency, indicating the system may not be adequately treating your water. Regularly checking for these symptoms can help you address potential issues before they compromise the quality of your water supply.
