Be Sure The Toilet Will Work In Your Building

Purchasing Guide

Pressure
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.

Noise
Listen carefully to the noise level of the toilet models you are considering. Some are quieter than others.

Building Pipes
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.
