how to Install a Garbage Disposal

Kitchen Garbage disposals are efficient, safe and virtually trouble-free devices that anyone who knows how to use a screwdriver and wrench can install it in a few hours. it does not take you much time, Due to its operation mode, it can be divided into 2 types. Type of Batch-feed,touted for their safety, are similar to a food processor. Once it is filled with waste, it’s activated when the sink plug is twisted into the sink opening. While a continuous-feed garbage disposal is operated by a switch on the wall or cabinet, and runs continuously while waste is fed into the grinding chamber.

Cold water must be kept running while a garbage disposal is working. The water cools andlubricates the grinding parts and helps to send the tiny waste down into the drain.

Step 1. Remove Drain
Remove the existing waste (drain) pipes from the sink strainer to the threaded fitting at the wall or floor (stubout).If the removed piping is plastic with compression (threaded-type) fittings, you can possibly use it again. But if the pipe is
welded or metal, throw it away. Unscrew the fittings by hand or with groove-joint pliers and use a hack saw to cutthe welded pipe.

Step 2. Replace Sink Strainer
Remove the sink strainer fitting that is secured to the sink bowl. One type of strainer is held with a largelock nut, but there are types that use three screws. In its place, install the flange that comes with the
disposer. Apply plumber’s putty under its lip to form a seal with the sink bowl.

Step 3. Install Mounting Assembly
Slip the mounting assembly gasket and mounting and retaining rings over the neck of the sink flange andtighten the screws. First tighten one, then the others a little at a time until the gasket and flange are bothtight to the sink bowl. Remove excess putty from around the flange inside the sink.

Step 4. Mount Disposal
Before you mount the disposal, make the wiring connections at the disposal .Be sure toallot enough cable to extend to the power source .Reattach the drain elbow. If you have adishwasher, prepare the disposal drain following the manufacturer’s instructions. Slip the disposal’s
slotted flange over the mounting bolts.

Step 5. Connect Plastic Waste Pipe
Connect a two-piece tubular P-trap to the drain elbow and the drain fitting at the wall (stubout). Asneeded, cut the P-trap and rotate both the trap section of the P-trap and the disposal. Complete
tightening the waste pipe fittings and the disposal. Connect any dishwasher hose to the disposal’s drainfitting with a stainless steel hose clamp .

Step 6. Power Connection
If you have electrical wiring experience and plan to make the power connection to the disposal, be sureto first turn off the power before beginning the work.
Disposals need to connect to a grounded 20-amp circuit. The steps in order to connect power differ witheach type of disposal. For example, continuous-feed disposals are wired to an on/off switch located on a wall or in the sink cabinet. Whereas a batch-feed disposal has its own integral switch and ishard-wired or plugged directly to the wall outlet. It is best to have an electrician handle this part of the jobif you are not knowledgeable about local code requirements and basic electrical wiring.
