Confirm against the model spec sheet before ordering.

Floor drains for HSJ-2557 are matched by S-trap entries at 200 mm (8 in) and 250 mm (10 in). Each printed entry is ordered as its own line. Wall wastes take the P-trap entry at 180 mm. Group rooms by entry and write each group as a line with its toilet count. Readings outside these values need another model. Washdown flush applies to all three entries, and the survey sheet should stay with the purchase file for the site team.

The bowl on HSJ-2557 is printed as rimless, and washdown is the single flush. The one piece toilet design joins tank and toilet bowl in white ceramic, the only listed color. Every line on the order therefore shares bowl, flush and finish. Request written confirmation of the outlet split and counts from the factory before production. Length is printed at 670 mm. Buyers specifying rimless bowls across a whole building can list this model with no flush or color fields.
