CARRIER STUD PLACEMENT 

If using 

in-wall carrier, set bearing rods as 

shown above.

SET DRAIN LINE HEIGHT 

17” from  

finished floor (standard 24” rim) or 10” for 

ADA installation. Threaded nipple should 

extend ½ to ¾” from wall.

A. 

Clean face 

of existing wall flange. 

B.

 Install the brass flange

 with the 

clear inspection disc. 

C. 

Slowly pour water

 into the drain.

D.

 Use a flashlight to check the pitch/

slope

. No water should be present in 

the inspection disc or nipple. 

E. 

Remove flange

 after inspection.

DRILL HOLES 

with ⁵/₁₆"

 

masonry 

bit for the lower anchor screws 

and insert plastic anchors.

TIGHTEN COMPRESSION 

NUT AND GEAR CLAMP.

DETERMINE THE DRAIN NIPPLE DEPTH

 

by measuring the distance between the 

back of the sanitary tee (or elbow) to 

the front edge of the nipple.

MEASURE & MARK THE ROUGH-IN 

if 

in-wall carrier is not used. Use a ⁵/₁₆" 

masonry bit to drill hole, then install 

the hanger bracket with one plastic 

anchor and screw.

• 

Check rough-in height to achieve 24” 

rim height (17” rim height for ADA).

 Check slope. Downhill slope, per code, 

is essential because waterfree urinals 

require gravity flow for drainage.

 Check DWV material. Suitable materials 

include cast iron, PVC, ABS, and 

galvanized steel.

• Never install on copper DWV due to 

copper’s susceptibility to corrosion

.

• 

Measure drain nipple depth (in inches)

   to find trim length (in inches)

Hang the bowl on the bracket 

and check tail 

pipe alignment, then remove the bowl and 

adjust the bracket as needed.

CAUTION

 After removing any urinal from the 

drain line, it’s normal for certain naturally occurring 

but

 potentially hazardous sewer gases 

to escape 

through the opening until the waterless cartridge 

is installed properly into the waterless urinal. If you 

need to leave an open drain line unattended after 

removing the urinal from the wall, temporarily wedge paper towels or a 

rag into the drain hole to reduce any outflow of sewer gases, and remove 

the paper towels or rag prior to completing the urinal or cartridge 

installation. 

Never smoke, have an open flame, or place your nose or 

mouth near open drain lines or waterless urinal housings into which 

a cartridge is not yet properly installed. 

You also can wear a breathing 

mask when removing or installing any waterless urinal or cartridge to 

reduce potential exposure to any such gases.

PLACE THE GEAR CLAMP 

and compression nut onto the 

housing tailpipe.
