Pentair Diffuser Assembly | Triton II Sand Filter TR100 | 154462 C6430 Total alkalinity in spa waterThe Pentair Diffuser Assembly (154462) is the OEM replacement diffuser for the Triton II Sand Filter model TR100. The diffuser sits at the top of the filter's internal standpipe and distributes incoming water evenly across the sand bed. A cracked or degraded diffuser concentrates flow into a narrow channel, bypassing large portions of the sand media and reducing filtration effectiveness. Replacing a damaged diffuser restores proper water distribution
