Joe Wise: Hi, I my name is Joe Wise, owner of Built Wise Construction in Orlando, Florida. Today we are covering how to change out a garbage disposer. In the last clip you saw us turn off the breaker and turn off electricity. I am just going to reach up here and flip the switch just to make sure they were not hot so we wouldn't have any problems and then we will go to start disconnecting the unit itself. That's where your pot is going to come in handy, maybe a towel here for your back as you lean in here to get those work done and we are just going to start taking supply lines off. Now the supply lines can be PVC or metal. The PVC are just hand tightened, metal are on there a little tighter so you may have to use tools like your pipe wrench or a pair of channel locks. Alright, I was able to get that one off by hand so I am going to pull off the P-trap first. Now there is water in this P-trap so you want to make sure you have your towel ready and have your pan underneath it to catch any excess water that may drain out. You can see that water dripping right down there. I am going to continue to take that off. Now the P-trap is put on there primarily to keep the water and smell out of your kitchen. It traps water in there, it traps the gas on the other side of the pipe so you don't have to smell your sewage. Now we are disconnected from that, I am going to have to disconnect the line from the waste line from your dishwasher, disconnect that. Well, this tailpiece is spiral one so, a little too tight for me to get off by hand so we are going to use a pipe wrench. I am going to call these monkey wrenches, I am not quite sure why. The proper way to use that is to put this on the bolt in the direction that you want to pull and as you can see, when you are clamped down on that or when you pull on the hand or put leverage on it, it actually tightens on the nut and that's the direction you want to pull in. Remember, right-tighty, lefty-loosey. Oh, that went on there very well and as you see, we tried to pull that off of there and the whole unit came loose. I have always found that when you are doing this kind of repair, it's easier just to replace all of the plastic or all of the metal up underneath here. We start from scratch, because this one has been repaired a couple of times and it's not coming off very clean. I can see where it has been sealed with some kind of caulk or plumber's putty or something in here and it is not breaking loose evenly. So that's not coming out very good so what I am going to do is actually just disconnect it from the unit itself and we are going to throw that away anyway so it shouldn't be an issue. That's on there pretty good. I take it then off with a screwdriver. So I have to add a little one tool to our tool list here, a little socket wrench, with a socket on it, whichever size fits, we are going to put that on there, see if we can loosen this, the way is to bop off the unit itself. There we go. We got it this time. We get a little bit more leverage on with the socket than you can with a screwdriver. I am going to take this bolt off at the top. Sometimes these are held on by two bolts, but this particular unit has one. Then we are going to just relieve it, take it off of here. As soon as you get this bolt out, I am going to twist the mounting - the unit in the mounting assembly and we are just going to drop the whole unit out and down off this mounting assembly. There that got rid of the supplies, it gets nasty in this. I am going to take a tool that actually comes with the new product that we didn't show you. It's for -- for it came with the new disposer. It sits up in the, I will show you in a minute on the new and they just twist it counterclockwise and the whole unit comes out of the mounting assembly and falls down very easily. Now that we got this off, I am going to go the electrical and disconnect the wires, I am trying to turn it when you can see here, but it is difficult. We are going to take the ground wire off, that's the middle copper wire that doesn't have any insulation on it, then we are going to pull out the -- there is the black -- black on the unit, see that one didn't have a very good connection and there is the white. Then we are going to take the wire out of the old unit, remove this. Just dispose all of this and put it in very correctly. To begin with, it should have had a mounting hardware here to cover this and that as you can see, when it pulled loose that wire wasn't on there very well. You want to make sure when you are doing in these wires, you get those wire nuts on there properly. There we go, now the whole unit is out of here and now we will get started on installing the new disposer. 2

Garbage Disposal Backed Up by rolexus1117 at 04/25/09 02:49PM Flag

Joe, Thanks for your videos! I had stuffed to much gabage in my disposal and it backed up. I could hear that the disposal was working so I figured the garbage was backed up in one of the pipes. Thru your videos I saw how the piping worked and in 30 mins, a non-handy woman had her garbage disposal fixed. It felt nice to be able to do it by myself! Thank you!
