1. Is there any reason I have a slow initial flow rate?
This may be due to the wrong installation of the carbon filter. You can check this by removing the filters from the system and submerging them into a tall container containing clean water, such as the lower chamber of your filtration system. The filters either sink or float. Floating means the micropores contain trapped air, while sinking signifies complete saturation. Transfer the filter cartridges into clean water and allow them to sink to the bottom before reinstalling them into the system.
NB – What you have in your water filtration are fluoride filters. Hence, it is understandable to have a slower flow rate of about 15-20% less under normal conditions.
2. Why is there water in the upper chamber after filtration?
Having one or two inches of water in the upper chamber post-filtration is expected. Since you have gravity filters, the water level in the upper chamber drops and leads to a slower filtering process. This is normal, considering there is less water pressure available to push water through the filter elements.
3. The TDS levels did not drop after filtration. Is this normal?
This system is not designed to primarily reduce TDS, which is the total amount of mobile charged ions in water. TDS include metals, salts, and minerals, all dissolved in a specific volume of water. Being a gravity-fed water filter system, the filtration process does not eliminate the beneficial materials. It only reduces the harmful materials. You can get a Waterdrop RO water filtration system if you want a filter system that does both.
4. What is the model number of the replacement water filters, and where can I find them?
For the white fluoride filter, the model number is PF-2-C, while for the black carbon filter, the filter number is BB9-2. You can find them by searching for the model numbers.
