The Clean Pea Gravel Filter Media (30 kg / 66.1 lb Bag) is a washed, dried, and precision-graded sub-angular to rounded siliceous gravel engineered specifically as an underbed support layer for commercial and residential deep-bed granular filters (including sand and dual-media pressure filters such as Triton TR100/TR140, Bobcat, and multi-lateral commercial vessels). Formulated to comply with AWWA B100 and NSF/ANSI Standard 50/60 specifications, it is placed directly over the internal lateral hub assembly or plenum plate to protect lateral slots from sand intrusion, ensure uniform hydraulic distribution during backwash cycles, and prevent channeling across the primary filtration media bed.
