I am owner of built wise construction in orlando florida and today we are going to go over how to install a garbage disposal.

Our garbage disposal is 6 1 2 from flange to center. Now the water outlet on the garbage disposal is several inches lower than the drain itself and water is sitting in the garbage disposal. After getting the new disposal attached to the sink i saw why the sink is too low the wall drain is too high it s a good 2 inches higher than the disposal. Garbage disposal is lower than main drain.

We have a 10 deep sink practically 11 to the drain hole. However when they moved the drain they made it too high. So our garbage disposal will have a drain 17 above the floor. The main drain pipe will always be connected but depending on your needs the dishwasher drain pipe may or may not be needed.

Connect a strait discharge from the disposal to a trap and use a wye to connect the traps to the drain line. A garbage disposal has two possible connecting points. Most garbage disposals have the outlet and downward facing waste pipe at about 10 from the top of the disposal which sits at the bottom of the sink and then there is a u or p trap that attaches from the outlet to the waste drain. Now we are going to hook up the waste pipes coming off the disposal.
