dont ....they are a pain in the ass
putting the hangers up and putting backing in the wall is
the easy part of the job...
installling the sloan valve to the right specs can get a little interseting.too....
the worst p[roblem I have had with them is to get the drain right.....
if you use a normal 2 inch tee in a normal 4 inch wall you are screwed
because it will push the drain line way too far out and then you cant
keep the urinal flush with the wall
if you hold the pipe back as far as possible and install a
2 inch cleanout type tee....on center where the drain is supposed
to go you will give yourself about an extra inch or two to play with....
which is usually desperately needed with about every urinal I have
fought with...
even if you have a 6 inch wall to work with I would still hold
that drain back as far as possible and use thecleanout type
tee and then you have plenty of room for whatever type brass
flange and nipple size you will need...
its always best to come up from below on center with your drain
rather than to have an arm in the line... because the arm or horizontal
branch will always stop up
and most likely get in the way of the backing
if any of this makes sense .... great...
have fun...
its a wonderful experience. ....especially with a used one.....
