To avoid this, make sure the new garbage disposal installation kit includes a tube, or buy one separately at the same time for nearly $three.
Shortcut: Keep the flange

Place an old towel nether the weight so you don't scratch the sink. If the bottom of your sink is quite concave, the old disposal might not contact the flange. In that case, place a can on the flange, then counterbalance downwards the can.
Step 9
Tighten with pliers
Easier on the wrists
When y'all hang the new disposal, rotating the lower mounting ring tightens the seal betwixt the disposal and the sink flange. The lower band rides up a gear up of ramps on the upper band-pretty neat! Just the concluding inch or so of rotation requires a fair amount of strength.
The easiest manner to apply that strength is to squeeze them together using natural language-and-groove pliers, such as Channellocks. You lot'll need medium or large pliers to exercise this.

Measure out the distance
A disposal's discharge tube must slant about 1/4 in. downhill in order for it to drain properly (see Figure A). Creating that drop may exist a small problem if the outlet on your new disposal is lower than the outlet on your old one.
To be prepared, measure the distance from the outlet to the top of each disposal before you remove the one-time unit. If the new unit's outlet is lower, you must also lower the tee that the discharge pipage connects to. Loosen the 2 basics that connect the tee to the tailpiece above and the trap beneath.
