The standpipe positions internal laterals within the filter tank to ensure uniform flow across the entire media bed. It directs water downward through the filter media then upward through the laterals for thorough debris capture. The structure maintains steady pressure and prevents channeling or bypass, so filtration remains efficient and consistent over time. That stability helps preserve water clarity and extends filter life by ensuring media use remains balanced.
