DRAIN SADDLE INSTALLATION
1. The drain saddle assembly should be installed above the trap and on the vertical or horizontal
tailpiece. To reduce the drainage noise, mount the drain line as low as possible above the trap, or on
the horizontal tailpiece.
2. Next, align and install the drain saddle clip with the tubing connection port onto the black sponge.
This will cushion any gap between the saddle and the pipe. Make sure the hole on the sponge is
thoroughly punched out, and is aligned to the hole on the saddle to complete the installation.
Step 1 Step 2 Step 3
3. Make sure to align the drain saddle hole to the drilled hole perfectly. Mis-aligning these two holes will
block the drain water and cause membrane damage. Attach the drain saddle to the drain pipe and
tighten the two screws evenly.
4. Once the drain saddle is secured, push 1/4” black drain tubing into the Quick Connect fitting on the
saddle. DO NOT use an “Insert” on the drain tubing.
