Drain Saddle
The Drain Saddle is used to connect the Drain Line to a drain pipe under the sink, or other drain plumbing.
The Drain Saddle is designed to fit around a standard 1.5 inch OD (outer diameter) drain pipe.
NOTE! Adjustable drain saddles are available upon request if the saddle does not fit your pipe.
The Drain Saddle should always be installed above (before) the P-Trap and on a straight vertical or horizontal
section of pipe. To avoid clogging the drain line with debris do not install the Drain Saddle after the drain
pipe meets a garbage disposal or dishwasher drain. The image below shows ideal Drain Saddle locations.
1. Once you have found where your Drain Saddle will go on the Drain Pipe make a mark for the opening
there with a marker or pencil.
2. Use your drill and 3/8 inch (9.525mm) drill bit to drill a hole at your mark. Be careful to drill through one
side of the pipe only and stabilize your pipes while drilling to avoid damaging them.
3. Find the half of the Drain Clamp with a hole in its center. Then remove the backing from the Foam Gasket
(the foam circle at the center of the Gasket is disposable). Make sure to align the Foam Gasket hole with the
Drain Clamp hole and stick the adhesive side of the Gasket to the inner wall of the Drain Clamp half.
4. Take the half of the Drain Clamp without the Foam Gasket and insert a nut into the recess on each side.
5. Position both halves of the Drain Clamp on the drain pipe with the clamp’s opening aligned over the
drilled hole. The Foam Gasket will be between the drain clamp and the drilled hole. Push your 3/8 inch drill
bit through both holes (the Drain Clamp hole and the hole in the Drain Pipe) and remove to verify that the
clamp is properly aligned with the hole you drilled.
6. Secure the Drain Clamp halves together in place on the Drain Pipe. Screw the bolts through the Drain
Clamp half with the Foam Gasket and into the half you installed the nuts. Do not over tighten. When
tightening bolts make sure there is equal space on both sides between the Drain Clamp halves.
