Siphonic One-Piece Toilet, 10 Inch Rough-In

HSJ-2478 is a 27 inch siphonic one piece toilet, 10 inch rough-in being its single S-trap entry. On S-trap, HSJ-2425 prints 250 and 300 mm; HSJ-2478 prints 250 mm. On size, HSJ-2425 prints 680 × 400 × 760 mm; HSJ-2478 prints 690 × 400 × 770 mm. Both list siphonic or washdown flush and a 180 mm P-trap. Buyers whose drains all read 10 inches can choose either on size. Confirm against the model spec sheet before ordering.

Floor drains on an HSJ-2478 project must read 250 mm (10 in) from the finished wall to the drain center. That is the single S-trap value printed. Drains reading 300 mm or more need another model. Wall-waste rooms take the 180 mm P-trap version instead. Log each reading on the survey sheet, then group rooms into lines with toilet counts and flush version for the RFQ. Keep the readings with the purchase file for the site team.

Siphonic and washdown are both listed for HSJ-2478, confirmed at quotation. White ceramic is the single color, and the one piece toilet design joins tank and bowl. Projects with a house flush standard set one version for every line. Request written confirmation from the factory of the flush version on each line. Width of 400 mm (15.7 in) and height of 770 mm (30.3 in) complete the layout data for the bathroom.
