FAQs
What footprint does the HSJ-2496 washdown one-piece toilet take?+
Which outlets does HSJ-2496 list?+
How does HSJ-2496 compare with HSJ-2558?+
HSJ-2496 washdown one piece toilet data starts with a printed length of 700 mm (27.6 in) and width of 380 mm (15.0 in). Height is 820 mm (32.3 in). The catalog lists S-trap rough-ins of 250 mm (10 in) and 300 mm (12 in) and a 180 mm P-trap outlet for this white ceramic body. Verify against the official technical drawing before fabrication of fitted furniture in the bathroom.
S-trap entries on HSJ-2496 match 250 mm (10 in) and 300 mm (12 in) floor drains. The P-trap entry at 180 mm matches wall wastes. Measure every drain, group rooms by reading, and write each group as an RFQ line with its toilet count. Readings at other distances need a different model. Confirm against the model spec sheet for each entry before the purchase order is released. Washdown flush applies to all three entries.
Washdown is the single printed flush for HSJ-2496, and white ceramic is the single color. The one piece toilet design joins tank and bowl in that body. Every line on the order therefore shares flush and finish, which suits a building that needs identical bathrooms on every floor. Outlet and count are the only variables. Request written confirmation from the factory of the outlet split before shipment planning. Floor mounted placement applies to every entry.
