FAQs
Can one 26 inch swirl flush one-piece toilet, 10/12/16 inch rough-in, cover all my drains?+
What does swirl flush mean on HSJ-2390?+
How does HSJ-2390 compare with HSJ-2528?+
HSJ-2390 is sold as a 26 inch swirl flush one piece toilet, 10/12/16 inch rough-in. Each printed rough-in value is a separate S-trap version: 250, 300 or 400 mm. Rooms with a wall waste skip the floor reading and take the 180 mm P-trap version. Group rooms by reading, and the groups become RFQ lines with toilet counts. Confirm against the model spec sheet before releasing the order.
Flush version on HSJ-2390 is a line-level field: swirl or washdown. Projects with one house flush type set the same version on every line, while mixed projects split by room type. White ceramic is the printed color of the floor-mounted one piece toilet body, so color is not a field on any line. Request written confirmation from the factory of the flush version on the final order, alongside the rough-in for each line.
Length on HSJ-2390 is 670 mm (26.4 in) and width is 360 mm (14.2 in). Height is 760 mm (29.9 in). The catalog prints this one size for both washdown and swirl flush versions, with S-trap rough-ins of 250, 300 and 400 mm and a 180 mm P-trap outlet. Verify against the official technical drawing before fabrication. The 26 inch label rounds the 26.4 in length.
