The filter device made by yourself (filtered with sand) can you drink it after filtering? How do you think of using sand.I haven't learned physics.
The well water used is muddy water. I bought a front filter. After the installation, the water filtration has just begun to pay off. But after a while, the water is muddy again. what's going on? Check the filter element for damage or internal leakage. The filter inside the filter has two outlets. one removes dirty water. The other is that the water purification filter is not a purifier. the subtle soil filter cannot be completely filtered.
