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.
To maintain adequate wall gap between the back of
the tank and wall, mount the floor flange at a nominal
12” rough-in distance.
Ultra-low high efficiency toilets require a system with
adequate supplemental flows from other water usage
fixtures and a 4" ID drainline with minimum 2% slope
and maximum linear runs of 60ft.
