Order of connection with fixture and piping, 1. Japanese style closet (FL-854), 2.Western style closet, 3. SK, 4. Urinal.

From Japanese style closet to sleeve a: FL-854 (Japanese style closet) - 20 (length approx. 2m, inclination 1/100) = FL-874 (sleeve a)
From Japanese style closet to sleeve b: FL-854 (Japanese style closet) - 30 (length approx. 3m, inclination 1/100) = FL-884 (sleeve b)+ However, in this example, connect with FL-1250 (sleeve b) in order to avoid the SK drainage water pipe front of PS by
dropping at 45 degree.
