Hi my name is Bill and today I'm going to be showing you how to replace or install a
garbage disposal the reason why you might have to do this is because your old garbage
disposal is no longer working or because you don't have one in the first place and you
want to put one in For this repair we'll be using a flat head screwdriver a phillips head
screwdriver a putty knife a hammer a couple of wire nuts and a serrated knife or a hacksaw
you also may need to use some plumbers putty the first thing you need to do is find the
circuit that goes to the disposal and turn that off so after we've verified that there's
no more electricity running to our unite we're going to start unhooking the old one so right
here we have a drain line our dishwasher into the disposal that we have to disconnect we
also have the main pipe from the disposal and out and then we've got our electric wires here
so I'm going to start at the top and just work my way down and once that's loose we'll
pull it right off and now we'll just get that out of the way so the next thing we're going to
do is remove this pipe here the easiest way to get that is remove these screws here so now that
those screws are off we'll move this down and that'll pull out and we'll just twist
it out of the way so for the disposal unite here just as a kind of a better shot since
you won't be able to see it under the sink what we've got here is the locking mechanism
so to get this off from the flange on top you're going to want to twist the metal piece
right here and that'll come off and then you'll be able to remove your disposal when you're
putting it back on same thing you're going to line up this little knob right here with
the hole and then turn it and you'll want to turn it as much as you can and once you
have it locked into place you should be good to go and now we're going to want to twist
the old disposal off if you're having a hard time like I was you
can start by pounding it a little bit with a hammer but once you have it loose it'll
come right off so now that we have that down you have to get this screw out and get it
into the panel here now I'm just going to pull these out and show you so you can see
right here the way that these are connected you've got a couple of wire nuts on it so
you're just going to unscrew the wires nut on both of these
and you're going to untwist the wires separate them so these are the ones that go to our
old disposal these are the ones that go to our outlet so we're going to have to take
these out now so the next thing we're going to do now is loosen this screw here and once
that's lose enough should just pull right out and we'll put these wires here they're
a bit ridged so just have to kind to bend them so they're straight and then we can pull them
out and now we'll get rid of our old disposal now we have to take the old sink flange out
to do that we're going to remove these three screws and now this is nice and loose so we
and now this is nice and loose so we can kind of just twist that and
get all that old seal out there and now that we've twisted
it that's kind of loosened up this top piece here I'm just going to pull down on it
if you can kind of twist it there's putty and stuff from the old one hold it in place with
a couple twists so we get all that old stuff out of there and now we have a retaining ring
I'm just using a flat head screwdriver I'm going to pry that up and I'm going to hold
on to this stuff so it doesn't fall down on me and now you should be able to push up the
old sink flange and the next thing I'm going to do is I'm
just going to use a wet paper towel and just get the rest of this old plumber putty out
of here clean it all off so I can make room for the new stuff do as best as you can
to get it all off you'll want to make sure that we've got a nice water tight seal so
now I'm just going to use a dry paper towel and make sure we dry our sink out right where
we're going to be putting our new flange and putty so this is the disposal unit we'll be
using to replace our old one it's a GE model is GFC525V if you don't have one already you
can find one on our online store now this model comes with the disposal it comes with
the splash guard this will stop anything from coming up when the disposal is running goes
in just like that you've got a stopper here and we've got the extra accessories needed
to connect your disposal to you drain pipe so for our purposes we're going to be using
a disposal that was hard wired into a switch however this one has it's own plug now you
could always take the bottom off take the plug part and hard wire this one in as well
it's always an option but it is a little bit difficult they don't make it easy to get your
fingers in here to pull any of this stuff out so you can cap off the old one if you're
hard wired in or just make sure that you're getting one that you're going to have time
to hard wire we're not really going to show you how to cap off the old electrical system as that
should be done by a professional and it's not something that we want you doing at home
by yourself so if you don't have a disposal already hooked up to your sink you can just
skip the other steps where we're removing the disposal but you'll still need to put
on the flange and everything else to be able to hook everything to the bottom of the sink
then you'll be able to plug this into the outlet however you do need to make sure that
the outlet has on off switch otherwise when you plug it in its going to just turn on automatically
and you don't want that so I can plug it in and show you exactly what happens for example
if you plug it into a wall outlet so now I'm going to show you what exactly happens when
you plug it in with an outlet that doesn't have an on off switch which you DON'T want
to do I'm just doing this for demonstration purposes so you can see for yourself and you
don't have to risk anything I've made sure that everything is out of the disposal and
nothing going to come flying up if I turn it on and I'm just going to hold it so it
doesn't go flying anywhere when it goes on so you can see here it's plugged in turn itself
on automatically that's why you need to make sure that whatever outlet the plug goes into
that there's a switch for on and off so that you can turn this on or off whenever you need
to use it and then this metal piece comes off now we're going to unscrew the plastic
piece here set that off to the side now we have a couple of gaskets this gasket is going
to come up underneath I'll show you that and then this rubber gasket if you look at these
instructions it says for stainless steel sinks but we don't have a stainless steel sink here
so we're going to use plumbers putty but if you do have a stainless steel sink than instead
of using the plumbers putty you would use this rubber gasket as it says in the instructions
so now we're going to put the flange in when you do that you can set it down and then just
push down to get a nice seal on their and before we cut this putty make sure it's
not wet we're going to go underneath and put our other gaskets and flanges on tighten it
up and that'll expose some more of the putty when it get tighter and we'll cut it
all off so from the bottom here you can see some of the putty came out through here as
well so we'll remove that excess putty real quick or you can kind of just push it up in
there either way is find but we just have to get it out of the way of our threads so
now we're going to put our first gasket here that'll go all the way up to the top the putty
will help it stick to the top there and now we have this flange here and the way that
you can tell which way it's suppose to go there's an arrow facing up on it make sure
it's pointing up and we can screw that on and we'll screw that on nice and tight and
once you can't screw it on anymore you can take a look at the top and see all the extra
putty squished out and we'll clean that up so you can see here we have a nice tight seal
here and it's pushed out some extra putty so this is actually just pretty easy take
it out by hand just get all of that extra putty out and what you can kind of do is smash
it all together and go around and clean up the extra mess or if you're having a hard
time like with this stuff right here get a putty knife or another tool with a blade and
just scrape the rest out now we're putting this back up here and you're going to want
to make sure that you put it on the right way you'll know it's the right way cause the
bottom here has this part that will connect onto your disposal so you just put it right
in there and then we'll get our rubber gasket you're going to make sure you put it on the
same way you took it off this piece faces up the widest part on the bottom might be
a little bit difficult you just have to kind of work around as best as you can but it'll
snap into place just like that and now we've got everything ready to put the disposal on
so now what I'm going to do is pull out this old pipe here and you can take a look at it
if the pipe is good enough you can keep it and that way it'll save you a little bit of
work not having to cut a new one but we'll get that off and get the old piece right there
I don't really want to use that as our brand new disposal with this piece all we really
have to do is wash it off like I said again though you can use this also as a template
to cut your new one so if this is pretty worn out or pretty beat up you can grab your new
one measure it with that draw a line or something and then cut it when you need to now we need
to cut our pipe to length so what we're going to do is we;re just going to kind of pair
both of these here and this one is about right there I'm going to do a little bit more though
just because we can always cut off again if we need to so we'll cut it off right about
here now it's best to have the proper tools when you do something like this I have a serrated
knife instead of say a hacksaw because not everyone has a hacksaw at home most people
have these serrated knives though it's going to dull your knife not going to lie you're
probably not going to be able to use the knife anymore but it works in a pinch so we'll just
cut around the pipe here and try to do your best to cut a straight line all the way around
notice I'm also wearing my gloves especially doing something like this I want to make sure you're
staying safe you can't really tell but I'm through on this side and I'm going to continue
cutting around alright and now just break it off it's a little rough around the edges
definitely not my best work but it'll do now before I climb under the sink again what I'm
going to do with our new disposal is I'm going to get rid of this orange sticker here now
what this is is it's for the dishwasher drainage so if you don't have a dishwasher drainage
already hooked up you don't need to worry about this part however for our example we
do have a dishwasher hooked up so we need to take this sticker off and then what we
need to do is get a screwdriver or something else and poke in here and kind of give it
a couple taps and there's a piece of plastic it's a plastic plug you can probably knock
it out the other thing is if you can't knock it out cause it's really in there you get
a hammer and tap on the end of that screwdriver there we go so here's the plastic plug we
knocked out it's in a few pieces so I'm just going to make sure I clean up the disposal
get the rest of those little chunks out unscrew the bottom panel of your disposal I'll be
pulling out the wires through the round hole here and we're going to connect the white
wires together and once the wires are connected we'll use a wire nut to secure them now we'll
do the same thing with the black wires we're going to twist the wires together and once
they're twisted together use a wire nut to secure them and push the wires in one at a
time so we can fit through the hole now we can put the plate back on and screw it back
down so now what you're going to want to do is make sure the disposal is facing the correct
way you have your connections here near the pipes then you can bring it up and line up
these other little pieces here that connect onto the sink and once you have that lined
up just twist it into place and then adjust it as needed like so and now what we're going
to do is put our rubber gasket on first put that all the way up so it goes around the corner
and there now put this metal piece on and we can put the pipe into the other pipe there
now we just have to attach the piping here so we just have to adjust it a little bit
put this piece in place and just make sure to screw this down nice and tight into place
so we don't get any leaks and then there we go and now we can connect the dishwasher so
just line up the hose right there and put the clamp forward into place and tighten it down
now you can go back to your circuit breaker and turn it back on now we can put this flash
guard in and we'll just make sure that goes in there sits nice and tight and just push
it down around the edges until it get to the bottom and then you have this part as well
so you put the stopper in there whenever you want to plug up your sink we'll just leave
it out for now run some water just to test it and make sure there's no leaks and we'll
turn it on and make sure everything is working properly so it sounds like we don't have any
problems and your repair is complete if you need to replace any parts for your appliances
