Understanding Proper Drainage in Water Filters

Firstly, understanding how water filters function is crucial. During the filtration process, impurities are trapped, leaving cleaner water to pass through. Ideally, this filtered water should collect in the reservoir, ready for use, while the captured contaminants and water are drained out. When this drainage process is blocked or inhibited, issues arise.
