Attach the garbage disposal unit to the sink as you would normally. The last task that is done when connecting up a garbage disposal is the drain piping.
Attach the supplied 90-degree bend to the drain port on the garbage disposal. These are supplied with all new units, or they can be found at any hardware store. Push the gasket onto the end that goes into the disposal, then line up the pipe and hand-tighten the PVC nut to make a firm waterproof connection. Alternately, instead of connecting the 90-degree pipe, attach a regular 1 1/2-inch PVC pipe in the exact same way.
Hook up the sink drain trap to either the 90-degree disposal pipe or to the extension. Push the nut onto the pipe, place the gasket over the end to be hooked up and link the pipes together. Thread the pipe nut onto the connector threads and hand-tighten it firmly.
Things You Will Need
- 1 1/2-inch PVC drain pipe, length determinate
- PVC nut
- The extension can be cut to the correct length with a hacksaw if need be.
