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.
