Frequently Asked Questions

Toilets - Installation

The supplied wax ring will not reach the floor flange. / My flange is below the floor.  Can I add more wax rings to reach the flange?

Often when a new tile or wood floor is installed, the floor is trimmed around the flange, leaving the flange below the floor.  Per plumbing codes, the flange must be above the floor.  You will need a flange extender which is readily available at your local building hardware store.

Do I need to use silicone to seal the bowl to the floor?

Some homeowners like the bowl sealed to the floor and some do not. But, please note if you seal the bowl to the floor, it will be difficult to know if there is a leak.

My toilet rocks on installation.  How do I stop it?

For optimal performance and comfort, having a level toilet is recommended. However, floors, particularly in older buildings, sometimes have high and low spots that cause the toilet to rock or not be level. First, be sure the outlet horn of the bowl is not sitting on the flange. (If it is on the flange, you will probably need a new wax seal.) Second, to ensure the toilet is level, use a carpenter's level throughout the installation process. Third, use permanent shims between the bowl and the floor to level the toilet.

What else do I need to install my Delta Prelude™ toilet?

In addition to the items that came in your Delta toilet box, you will need a supply line to connect the toilet to the water supply shut-off valve and a tube of silicone to help secure the toilet bowl to the floor. You may also want safety goggles, a flashlight to see behind the toilet, and a blanket or other soft surface to set the toilet on while you install the mounting bolts. It’s also a good idea to have someone on hand to help you install the toilet bowl.
