BACK-TO-BACK INSTALLATION

Recommended fitting type for 

back-to-back installations.

Depending upon your plumbing and venting conditions, the flow from the 
toilet in a back-to-back installation may create a vacuum on the system 
and draw water from the opposing bowl. The National Standards Plumbing 
Code prohibits the use of a cross fitting for drainage as throw over is 
possible. The code does approve a directional "Y" style fitting with proper 
venting to direct the water downward and away from the other toilet.

When installed so top of seat is 17" to 19" (432mm to 483mm) from the finished floor. MEETS THE AMERICANS WITH DISABILITIES ACT 

GUIDELINES AND ANSI A117.1 REQUIREMENTS FOR ACCESSIBLE AND USEABLE BUILDING FACILITIES - CHECK LOCAL CODES.
