Sure The Toilet Will Work In Your Building
While true gravity tank toilets will operate at water pressures of only 10 - 15 psi,
pressurized tank and flushometer toilets usually require 25 - 35 psi and, sometimes, even
more. This is the pressure at the toilet, not the pressure coming into the building. If
you are considering pressurized tank or flushometer models, be sure to have your plumber
or consultant survey pressures throughout the building. Buildings with roof tanks or
buildings that depend on street pressure may have lower pressure on the upper floors. Make
sure your building's pressure is adequate before switching from a gravity type toilet to a
flush valve type toilet.
Listen carefully to the noise level of the toilet models you are considering. Some are
quieter than others.
If your building has had previous problems with clogged or improperly pitched drain lines
or a bad venting system, these problems should be addressed as part of any toilet
replacement program. The installation of new low-consumption toilets may exacerbate
pervious waste line or venting problems. Have your drain line slopes checked before
replacing the toilets.
