Riser features two openings which connect to 3 in. to 8 in. drain pipes using appropriate outlet adapters, and can be sealed off with an outlet plug (outlet adapters and plug sold separately). The extension riser also fits on top of the 12 in. sump box to increase sump volume. The riser is made of high-impact polystyrene (HIPS) treated with UV inhibitors.
