FAQs
What drain does a 27 inch siphonic one-piece toilet, 12 inch rough-in, like HSJ-2480 need?+
How large is HSJ-2480?+
How does HSJ-2480 compare with HSJ-2347?+
HSJ-2480 is listed as a 27 inch siphonic one piece toilet, 12 inch rough-in. The single printed S-trap value is 300 mm, taken from finished wall to outlet center. A drain reading of 300 mm matches this model; other readings need a different toilet. Wall-waste rooms also need another model, because the catalog lists only the S-trap outlet. Log every reading on the survey sheet and confirm against the model spec sheet before the order is released.
Siphonic is the only flush type printed for HSJ-2480. Every toilet on the order therefore shares the same flush and the same 300 mm S-trap outlet. White ceramic is the single listed color, and the one piece toilet design joins tank and bowl in one body. Buyers who want one fixed specification for a run of identical bathrooms can list this product on a single line.
Height on HSJ-2480 is 695 mm (27.4 in). Length is 690 mm (27.2 in) and width 390 mm (15.4 in). The catalog prints this single size for the siphonic body with a 300 mm (12 in) S-trap rough-in. Millimeter values are as printed, with inches in brackets. Verify against the official technical drawing before fabrication. The 27 inch label rounds the 27.2 in length.
