INSTALLATION NOTES
Back-to-Back Toilet Installations:
 TOTO recommends the use of a nationally listed, 
double sanitary tee-wye only, in vertical waste stacks, 
in accordance with the stipulations noted in the 
majority of nationally recognized plumbing codes.
These dimensions and specifications are subject to change without notice
To maintain adequate wall gap between the back of 
the tank and wall, mount the floor flange at a nominal 
12” rough-in distance.
