The Waterco Baker Hydro HRV36 collector assembly with hub and laterals is designed for compatible sand filter applications where a major internal collection assembly needs replacement. A collector assembly is useful because it forms the central internal structure that works with the laterals to manage water movement through the filter bed.This replacement is especially useful when the original collector and lateral assembly is cracked, broken, or too worn to justify partial repair. Replacing a larger internal assembly like this can make a filter rebuild more complete and more dependable than addressing only one weakened part at a time.The 15B0227 is a strong service part when a compatible Baker Hydro HRV36 filter needs its collector assembly restored with the hub and laterals included. Waterco Baker Hydro HRV36 collector assembly with hub and laterals Designed for compatible major internal sand filter restoration Helps restore proper internal water collection and distribution Useful when the original assembly is cracked or damaged Supports a more complete filter rebuild
