Mountain Plumbing mt957r/pvdbb Perfect Grind Air Switch

Product Description

The MOUNTAIN PLUMBING mt957r/pvdbb is an air switch designed for use with garbage disposal units, commonly called Perfect Grind systems. It provides a pneumatic activation method, allowing the user to start or stop the disposal by pressing a countertop button that sends an air pulse to the switch unit. This eliminates the need for a wall-mounted electrical toggle at the sink location. Licensed plumbers and electricians install this type of component as part of a compliant disposal circuit, particularly where countertop switching is preferred or required by local code.

This air switch is suited for residential kitchen installations where a garbage disposal is plumbed into the sink drain. It is typically installed under the sink cabinet, inline with the disposal power circuit. The countertop button connects via flexible tubing to the switch body, keeping electrical components away from wet areas. This setup is common in remodel and new construction projects where a clean countertop aesthetic is desired alongside safe disposal operation.

Key Features

• Pneumatic activation eliminates electrical switching at the sink deck
• Designed for use with garbage disposal units in residential kitchen applications
• Countertop button connects to switch body via air tubing for remote operation
• Keeps electrical components separated from the sink wet zone
• PVD Brushed Bronze finish (pvdbb) for corrosion resistance and aesthetic coordination

Compatibility

Designed as an OEM-style air switch replacement or new installation component for residential garbage disposal systems compatible with standard air switch pneumatic tubing connections.

Installation Notes

Installation should be performed by a licensed plumber or electrician familiar with NEC requirements for kitchen disposal circuits. Disconnect power to the disposal circuit at the breaker before wiring or servicing the switch unit. Route the pneumatic tubing from the countertop button to the switch body without kinks or sharp bends that could restrict airflow. Do not install the electrical switch body in a location subject to direct water exposure.
