4. Mounting the Drain Saddle Valve
A Drain Saddle Valve is used to make a wastewater connection with
the drain under the sink and is designed to fit around a standard 1 1/2-

before (above) the p-trap and on a vertical or horizontal drain. To avoid
clogging the drain line with debris, do not install the drain saddle near
a garbage disposal. See below.
