Installing a garbage disposal is a key upgrade in many kitchens, adding convenience and reducing waste in household garbage management. With the right guidance and tools, this task can be managed by a DIY enthusiast, albeit with attention to detail and precision. The EZ Mount system, designed for ease of installation and removal, streamlines the process by allowing the unit to be secured without the need for tools typically associated with 3-bolt mounting. This article outlines the steps required to install the EZ Mount sink flange for garbage disposal units, detailing critical components and best practices to ensure a secure and functional setup.
Understanding the EZ Mount System
The EZ Mount system utilizes a unique design that enables users to install and remove garbage disposal units with minimal effort. Unlike the 3-bolt mounting system, which requires tightening three bolts by hand, the EZ Mount system allows the unit to be secured by rotating it into place. This system is particularly beneficial for consumers who may frequently upgrade their disposal units or those without access to installation tools.
The installation process begins with the sink flange, a critical component that serves as the interface between the garbage disposal unit and the sink itself. The flange is secured with a series of components that ensure proper sealing and vibration resistance. A fiber gasket is typically included to protect the sink while minimizing noise from the disposal motor operation.
Both the old and new mounting hardware of an EZ Mount system can be used if the mounting assembly matches, allowing for less hardware to be replaced. However, it is recommended to replace the old mounting hardware when upgrading, as wear and tear over time can lead to seal degradation and potential leaks. Maintaining a fresh seal with plumber’s putty or silicone can prevent future issues.
Preparation and Setup
Before beginning the installation of the EZ Mount sink flange, it is important to prepare the workspace. Cleaning the sink and drain area removes any debris that may interfere with the installation. Users should also ensure they have all necessary components and tools on hand, such as the fiber gasket, rubber cushion mount, metal mount ring, and discharge elbow. The sources indicate the importance of having appropriate tools like adjustable wrenches, screwdrivers, and pliers during the installation process.
It is also crucial to determine the sink thickness, as the EZ Mount system is ideally suited for sinks with thicknesses not exceeding 1/2". If a thicker sink is being used, an extended sink flange for Pro 3-Bolt Mount disposals may be necessary. However, for typical EZ Mount installations, the standard flange will suffice.
For new garbage disposal installations, users are advised to purchase a connection kit from a local plumbing supply center, typically costing around $10. This kit includes essential parts such as the P-trap and discharge elbow, ensuring compatibility with the existing plumbing setup. A dedicated outlet for the disposal must be wired under the sink, switch-controlled, and rated at 20 amps for 120 volts electrical circuits.
Installing the Sink Flange
With the sink and tools prepared, the next step is installing the sink flange. Begin by placing the fiber gasket on the flange. This gasket serves as a barrier between the flange and the sink, protecting against scratches and reducing vibration. The support ring is then threaded onto the flange to provide additional stability.
Once the support ring is in place, the metal mount ring and rubber cushion mount are added. These components fit together with complementary grooves that ensure the mount ring and disposal unit remain secure. The rubber cushion mount should be fully inserted into the groove at the bottom of the flange to prevent it from dislodging during operation.
To secure the sink flange, a weighted object—ideally the old or new disposal unit—should be placed inside the sink to prevent the flange from shifting during the installation process. A towel should be placed underneath the disposal unit to prevent scratches on the sink surface while the flange is being installed.
The fiber gasket and metal mount ring must be aligned correctly and then attached to the flange from beneath the sink. It is important to verify that the metal mount ring rotates freely around the cushion mount, indicating proper installation. At this stage, users should check all components for correct orientation and compatibility, particularly the black tab at the top of the unit, called the "hopper projection," which will secure the disposal in place once it is rotated.
Securing the Disposal Unit
Now that the flange is in place, the next step is to secure the disposal unit to the flange. Begin by aligning the hopper projection on the top of the disposal unit with the corresponding groove on the mount ring. Once aligned, gently push the unit upward into the mount. Supporting the disposal, rotate the mount ring so that the hopper projection moves from the larger to the smaller end of the groove. This rotation locks the unit in place, ensuring it is firmly attached and sealed against the sink flange.
The amount of plumber's putty used will ooze slightly around the sink opening during installation. This is a positive indicator that the seal is tight, provided the user does not overtighten the components, which could strip the seal or damage the sink. It is recommended to wipe away any excess putty after installation with a clean rag to maintain an aesthetically pleasing sink area.
For those replacing an old disposal, it is important to note that the entire upper part of an EZ Mount unit remains attached to the flange during removal. The hopper projection must be disengaged from the groove by rotating the disposal, which can be aided by using a screwdriver or similar tool for extra leverage. Should the user need to remove only the disposal unit, the rubber cushion mount can be pulled out from inside the mount ring, allowing the rest of the components to be detached.
Connecting the Plumbing and Electrical Systems
With the disposal unit securely mounted, the next task is to connect it to the plumbing and electrical systems. Begin by attaching the discharge elbow that came with the new unit to the drain pipe. This component is typically secured with a metal plate and a few screws or a clamp, directing wastewater downward as intended. A rubber gasket should be installed between the disposal unit and the elbow to ensure a watertight seal.
For single-bowl sinks, the slip joint nut and washer can be connected directly to the trap at the bottom of the sink. If the elbow proves to be too long for the trap, it can be trimmed to the correct length. Double-bowl sinks require additional components such as a continuous waste disposer kit, which includes a discharge tube, baffle tee, and tailpiece. These components ensure both bowl drains are directed to a single trap. Depending on the stub-out location, a center or end outlet may be required.
Electrical connections for the disposal unit should be made cautiously. An air switch is compatible with all Waste King units, eliminating the need for hardwiring. To use this method, simply plug the control module into a dedicated, grounded 120V AC outlet. If a switch-controlled outlet is being installed, make sure the outlet is rated for 20 amps and is within 5 inches of the sink drain.
Verifying the Installation
Once the disposal is fully installed and connected to plumbing and electrical systems, it is essential to verify that the setup is functioning properly. Begin by running water through the sink to check for leaks. If any water accumulates in the sink or beneath it, minor adjustments may be required to tighten the seal or reposition the components.
It is also important to test the disposal unit without food particles to ensure the motor is working correctly. If operation seems off or the unit fails to run, double-check all connections and ensure the disposal is correctly secured in the mount and the electrical lines are properly grounded. Troubleshooting may be necessary, particularly if the unit is new and compatibility issues might arise due to wear.
Common Installation Tips and Considerations
During the installation process, users should be mindful of several considerations to avoid complications. First, always use a plunger or similar tool to keep the disposal unit in place and prevent it from dismounting during operation. If the nut on the drain becomes stuck and turns the entire assembly while loosening it, use pliers from inside the sink to lock the drain in place, allowing the nut to be removed safely.
For users working alone, it is recommended to have a friend assist in holding the sink flange in place while installing the mount ring and support hardware from beneath the sink. This ensures the flange remains stable throughout the procedure and avoids misalignment.
Proper sealing is another crucial factor. It is advisable to replace the old putty with fresh plumber's putty or silicone to ensure a long-lasting seal. Failure to do so may result in leaks or odors, as the existing putty could have dried out or deteriorated over time.
Conclusion
The installation of an EZ Mount sink flange is a manageable task for those following detailed steps and using the correct tools and materials. Understanding the unique features of the EZ Mount system, such as the hopper projection and rotating mounting mechanism, ensures a secure and functional garbage disposal setup. Preparing the sink area, aligning components correctly, and carefully connecting plumbing and electrical systems are essential to achieving a leak-free and efficient installation.
For those who are unsure or prefer professional assistance, local plumbing supply centers offer installation kits and can provide guidance on compatibility issues or extended flange sizes. Whether replacing an existing unit or installing a new garbage disposal, attention to detail during the process will lead to a long-lasting, trouble-free system.
