Water-Powered Disposal

Prepare the Sink

1. First, we turned off the cold water valve under the sink.
2. We placed a bucket under the p-trap to catch any spilling water.
3. We loosened and then removed the p-trap and the extension pipe from the sink drain.
4. We then loosened the sink flange and pushed the flange up through the sinkhole to remove it.
5. We cleaned the flanged area with a rag to remove any putty or debris left around drain.
6. Next, with an adjustable wrench, we disconnected the cold water line to the sink.
7. With the main water supply off, we removed the shutoff valve.
8. We then applied plumber's tape to all the threads on the double outlet.

9. Next, we connected the new double outlet stop (figure A), making sure that the water outlet was facing up.
10. Finally, we reconnected the water line from the sink tap to the outlet stop.

Prepare the Disposal

1. We disassembled each part of the sink flange, laying the pieces out in order so we could easily reassemble them under the sink.
2. Next, we pressed a roll of plumber's putty around the sink flange (figure B) and then pressed the flange down into the sink drain hole (figure C) so that the flange was seated firmly in the putty.

3. We then set the flange gasket in place (figure D) and attached the ring by screwing it in place.
4. We locked the flange in place by tightening the screws (figure E).

Install the Disposal

1. We slid the on/off valve into the sink hole from underneath (figure F).

2. Next, we placed the splashguard on the disposal unit so it rested under the flange lip (figure J).
3. Holding the unit in position, we pushed it onto the sink flange and rotated it into position for the water connection (figure K).
4. We then set the ring clamp in place around the splash guard and snapped it closed.
5. Finally, we wrapped plumber's tape around the inlet valve, screwed the water hose to the disposal unit (figure L), and reconnected new piping and the "P-trap" drain to the disposal.
