HSJ-3004 is a 26 inch washdown two piece toilet with 10/12 inch rough-in versions, built as a separate tank and bowl. The two-piece build sets it apart from one-piece models in the same catalog. White ceramic is the listed color, and washdown is the single flush. The printed size is 660 × 375 × 790 mm (26.0 × 14.8 × 31.1 in). Buyers set only outlet entry and toilet count per line. Request written confirmation of the outlet split from the factory before production.
S-trap entries on HSJ-3004 sit at 250 mm (10 in) and 300 mm (12 in). Each printed S-trap entry is ordered as its own line. Group rooms by reading, then write each group as a line with its toilet count. Readings at other distances need another model. Confirm against the model spec sheet for each rough-in before the purchase order is released, and keep the survey on file. Sites built mostly on 10 inch drains can compare the 10 inch rough-in toilet collection.
Height on HSJ-3004 is 790 mm (31.1 in), the third figure in its printed size. Width is 375 mm (14.8 in) and length 660 mm (26.0 in). The printed size reads 660 × 375 × 790 mm in the order length, width, height. Washdown is the listed flush, and white ceramic is the listed color. Verify these figures against the official technical drawing.
