I replaced my water filter after noticing I had a trickle of water out of my refrigerator water dispenser which the problem remained post filter replacement. I also noted that the ice was hollow. This is a direct indication of a lack of water from the filter and filter housing or water control valve. To troubleshoot and test, first cut off your water supply and disconnect the water line from your house (on refrigerator side only) and see if the house is the issue by temporarily turning on the water while holding the water line in a bucket. If not, meaning you have plenty of water pressure from your house/wall side, turn off your house wall water supply valve. Reconnect refrigerator water supply line. Locate and disconnect the water filter line to your water control valve assembly inlet side from the filter housing. Temporarily again turn on the water supply. If there is no water replace your refrigerator water filter housing assembly. This was my issue and it fixed my water supply. If there is water, replace your water control valve assembly. The solenoid on the valve is stuck closed, burned out, or the water control valve is clogged with calcium deposits. Before replacement make sure that you have voltage on the electrical plugs to the water control valve. This eliminates any electrical issues. Happy Days!

As a general check up of our home water supply, we submitted 2 water samples for lab tests. One sample was directly from our kitchen tap and the other was from the refrigerator water dispenser with an EveryDrop Filter 3 installed (couple months old). Obviously, we expected better results from the filtered water compared to the direct tap water but lab results were mixed. 2 labs were used, both were EPA certified: 1 lab ran tests on contaminant levels while the other lab tested for bacteria in the water. The results were mixed. Without going into gory details, here are the highlights: CONTAMINANT TEST RESULTS: Much Lower in Filter water: (Good!) Aluminum Boron Copper Iron Strontium Similar in Both water samples: (OK. EveryDrop doesn't claim to reduce these) Calcium Conductivity Hardness as CaCO3 Silica Silicon Sodium TDS Chloride Fluoride Sulfate Bicarbonate Higher in Filtered water: (Not so good.) Nitrite Magnesium TURBIDITY Comparison: (a bit disappointing and worrisome about filter quality control) Tap Water Turbidity: 3.32 NTU EveryDrop Filtered Turbidity: 2.50 NTU (Even though 2.5 NTU is below the acceptable limit of 5.0 NTU, EveryDrop Certification claims 0.5 NTU post filter and so this is much higher than expected.) BACTERIA TEST RESULTS: TAP: HPC: 1 CFU/mL, Total Coliform: < 1 MPN/100mL, E.coli: < 1 MPN/100mL FILTER: HPC: 20 CFU/mL, Total Coliform: < 1 MPN/100mL, E.coli: < 1 MPN/100mL What doe it mean?: - Our TAP water supply is very clean in terms of bacteria. - EveryDrop Filter water had 20X value for HPC (Heterotrophic Plate Count) as compared to our unfiltered tap water. It turns out HPC of 20 CFU/mL is still way under the EPA limit of 500, but we have to ask: where is the added organisms coming from? Perhaps, the filtering material isn't as sterile as one would like? In summary: we are giving the filter 2 stars because while the water tastes fine, the mixed test results make us wonder how good is the quality control of EveryDrop filters.
