The following information relates to the installation of Waterless urinals in new installation and retrofit situations. Most US Plumbing Codes require urinals to be installed so that the non-ADA urinal lip to floor height is 24" (610 mm), and for ADA installations 17" (430 mm) urinal lip to floor.

NON-ADA URINALS

To determine the correct rough-in (drain line) height for non-ADA urinals, measure the distance on your current flushed urinal from the bottom of the screws on the urinal to the restroom floor. This is your current rough-in height (A). Then consult the urinal specification sheet of your Waterless urinal of choice to install. Look for the distance measurement between the urinal outlet and lip. (B).

Add A+B to come up with the lip to floor height the Waterless urinal will give you.

Example 1: (A) is 15”, (B) is 9” = 24” lip to floor. Simple exchange of urinal.

Example 2: (A) is 18”, (B) is 9” = 27” lip to floor. Lower rough-in height by 3” to come to 24” total.

ADA URINALS

To determine the correct rough-in (drain line) height for ADA urinals, measure the distance on your current flushed urinal from the bottom of the screws on the urinal to the restroom floor. This is your current rough-in height (A). Then consult the urinal specification sheet of your Waterless urinal of choice to install. Look for the distance measurement between the urinal outlet and lip. (B).

Add A+B to come up with the lip to floor height the Waterless urinal will give you.

Example 1: (A) is 8”, (B) is 9” = 17” lip to floor. Simple exchange of urinal.

Example 2: (A) is 12”, (B) is 9” = 21” lip to floor. Lower rough-in height by 3” to come to 17” total.

Waterless urinals install like any conventional urinal fixture. Each urinal comes with the necessary hardware plus two EcoTraps®. In most retrofit situations, you can use the existing flange from the conventional urinal to install the Waterless urinal. Saves time!

Approximate installation times are:

• Retrofit, simple change-out : 45 - 60 minutes
• Retrofit, lower rough-in : 90 -120 minutes*
• New Installation, with appropriate rough-in height: 15-25 minutes

Times are approximate and may vary according to present plumbing construction and materials.

*The additional cost to lower a rough-in may be in most cases 1 hour by a plumbing professional. This additional cost will usually just add a couple of months to your already short payback period.
