We will introduce a case where a guest-only restroom was installed on an OA floor where plumbing installation under the floor was not possible!
We would like to introduce a case where the "Wastewater 120NPB (OZ120-100NPB)" was adopted for a clinic in an office building tenant. In this case, there was a challenge of wanting to install a dedicated restroom for visitors, but due to the OA floor, it was not possible to install drainage pipes under the floor. Since the restroom would be used by unspecified individuals, there was a high risk of foreign object contamination, so a product with a backup function was adopted. A super water-saving toilet was used, and since it was not directly connected to the toilet, the inflow pipe length was kept within 2 meters and the number of joints was limited to 2. The pipe diameter was 75A, and the slope was set to 1/50 or more. [Case Overview (Partial)] ■ Installation Location: Office Building Tenant ■ Models ・Discontinued: Wastewater 120NPB (OZ120-100NPB) ・Alternative Model: Waste and Dirty Water Big NA (BG-201NA) ■ Connected Fixtures: Water-saving toilet (flush volume 5L, wall drainage, drainage center 155mm) and hand wash basin *For more details, please download the PDF or feel free to contact us.
