Step 5. Install the Drain Saddle Assembly
1. Select the location to install the drain saddle assembly. This is usually on the sink
drainpipe and needs to always be located above the “S” trap.
2. Position the drain saddle assembly in the selected location and mark the spot through
the threaded outlet with a pencil or marker
3. Drill a ¼” hole at the marked spot. Strip the backing paper from the adhesive side of the
saddle gasket and position on the inside of the drain saddle, aligning the hole with the
threaded outlet. Attach the drain saddle to the drainpipe, aligning the push-on port with
the drilled hole. Tighten the clamp snugly. DO NOT OVER TIGHTEN.
4. The black drain tube may be inserted directly into the push-on drain port, using
instructions in Step 8 below. Do not attach poly tube at this time.
