The installation of a Moen garbage disposal involves removing the existing unit and installing a new one. The process is broken down into two primary sections: removal of the old disposal and installation of the new disposal. Successful installation requires specific tools and adherence to a step-by-step procedure. Moen provides contact information for installation assistance and replacement parts.
Removing the Old Moen Garbage Disposal
Prior to beginning the installation of a new unit, the existing garbage disposal must be removed. This process involves several steps to ensure safety and proper disconnection of utilities.
Step 1. Disconnect Power: The first step is to disconnect the power supply to the disposal. If the disposal is plugged into an electrical outlet, unplug the power cord. If the disposal is hardwired, the electrical supply must be turned off at the circuit breaker or fuse box.
Step 2. Disconnect the Drain Line: An adjustable wrench is required to detach the drain line connected to the disposal’s discharge tube.
Step 3. Remove Dishwasher Drain Hose (If Applicable): If a dishwasher is connected, the dishwasher discharge hose must be disconnected. This hose is located at the top of the drain line. A screwdriver is used to loosen the clamp securing the hose to the disposal.
Step 4. Remove the Old Garbage Disposal: Once all connections are detached, the old disposal can be removed.
Installing the New Garbage Disposal
Following the removal of the old unit, the new Moen garbage disposal can be installed. This process consists of eight detailed steps.
Step 1. Install the Drain Assembly: The drain assembly should be inspected to determine if it can be reused. If the existing assembly and mounting ring seals are in good condition, they can be retained. Otherwise, a replacement drain assembly is necessary. The old drain assembly should be removed, and the sink surface cleaned thoroughly. A 1/2-inch thick band of plumber’s putty should be applied around the sink flange before inserting it into the drain opening. The drain assembly should be centered in the opening, and weight applied to create a tight seal, with a rag placed between the weight and the assembly to prevent scratches.
Step 2. Disassemble the Mounting Assembly: The new garbage disposal should be removed from its packaging. The mounting assembly is then disassembled from the disposal by turning the lower mount ring until it disengages from the ramps on the upper mounting ring. The upper mounting ring, backup flange, and fiber gasket are then removed from the sink flange. The sequence of these parts should be noted for correct re-assembly.
Step 3. Reassemble The Mounting Assembly: Working under the sink, the fiber gasket is installed closest to the sink, followed by the backup flange and upper mounting ring. These components are secured by aligning the snap ring and tightening the screws.
Step 4. Knock Out the Dishwasher Discharge Plug (If Applicable): If a dishwasher is connected, the factory-installed discharge plug must be removed. Failure to remove this plug will prevent proper drainage from the dishwasher. A wooden dowel is inserted into the dishwasher discharge line of the disposal and struck with a hammer to remove the plug.
Step 5. Connect the Garbage Disposal To The Mounting Assembly: The cable clamp is loosened, and the cable is separated from the disposer.
Step 6. Attach the Discharge Elbow to the Disposal: The discharge elbow is reconnected to the drain line, and a wrench is used to secure the connection. It is important not to overtighten the connection.
Step 7. Connect The Dishwasher Discharge Hose To The Disposal: The clamp on the dishwasher discharge hose is slid onto the disposal’s dishwasher discharge outlet and secured with a screwdriver.
Step 8. Attach The Discharge Elbow To the Drain Line: The discharge elbow is attached to the drain line using a wrench to secure the connection.
