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.
Press firmly.
