Well, by way of confession... I never completely completed that job. I mean, the dryer vented properly, but I never patched the drywall where the previous owner had butchered it, and I never properly plugged the hole to the garage where the dryer had been venting. Instead I filled up the hole with plastic bags and pushed our dryer in place to hide it.
In the past few months though, the dryer that came with the house has been getting slower and slower to dry clothes, and the washer has been leaking and thumping around a lot. We decided its time for a new laundry pair.
Then when bought the machines, we were shocked to find they wouldn't fit in the old spot and had to be stacked. Once they were stacked, the cord for the new machine couldn't reach the plug for the old machine, and long story short, it was time to finish the job I started three years ago.
I wasn't going to bother blogging about this for two equally good reasons:
- I've become blase about blogging. Basically I don't any more.
- Blogging about moving wires is about as boring as it gets.
but then I opened up the wall and was immediately BLOWN AWAY by what was in there, and just had to. Aren't you lucky. Basically this entry begins with a photo of a wall that's been opened up and cleaned up a bunch so you miss the whole dryer buying/stacking/attempt at plugging in and start right in with the good stuff.
The scene of the crime. You may be wondering why there is a white square around the area I am working. Its because the previous owner decided to just cover this mess with an oversized slab of drywall, then paint the wall. I guess that was an easy way to do things because all he needed was 6 screws to slab over the hole in the wall.
You may also have noticed that a stud has been cut about 5" above the floor and is being held up by... well, nothing. I guess the drywall screws are what's holding it. For those who haven't taken an engineering course, this is a bad thing. The bathroom above exerts a distributed load on the ceiling below which transfers that load through the studs to the floor in here. First priority - fix the stud.
Harder to see is the lint in the stud bay. Lots of it - from the dryer vent not carrying all the way through the wall. Lint means moisture, moisture is bad. Especially on a garage wall. But we've been through all that before.
The yellow insulation column on the left of teh picture is the vent stack for our gas water heater. There is a piece of metal strapping across the bottom of the picture - once upon a time it held the vent in place on the stud that used to go to the floor.
This is a double wall. It carries the main drain stack and venting for utilities in it, so luckily there is a lot of room to work in here. before i took this picture I used some extra insulation from the basement to stuff in where the insulation had been removed for teh old dryer vent.
Let fix the stud!
Hey fancy! I used the subheading autoformat tool! Anyways, in order to fix the cutaway stud, I needed to sister in new wood. You can see the stuff I used next to the drill in the photo above.
I like to hold the wood in place with a clamp to do this. It frees up a hand, and lets me line everything up before I use any fasteners. To prove I am not the ultimate handyman, I looked through my collection of odds and sods in the basement and got a bunch of 3" wood screws to pull teh boards together. They didn't match. If anyone asks, I'll say the previous owner did it.
Once that long board was in place with three screws through into the old stud, I put in a shorty below.
Apparently I also undid the screws holding the junction box for the laundry as well. Anyways, the little piece of wood was cut a little long to take the load from teh stud, and screwed to the new wood. Then both were screwed to the floor in opposing directions. Very solid.
It's time to get started on electric stuff...
Playing with Junction boxes - before reading any further, go turn off the breaker to your dryer.
Step one in this portion of the show is disassembling the existing box. The previous owner in his wisdom had used wood screws to attach the cover to this box. That was a bad idea for a few reasons - the pointy ends of the screws could have pierced a wire, they fit poorly, and they ruined the threads on the screw holes. Luckily though, he got the outlet wired properly.
The dryer outlet wires are just poked in holes and then screws are tightened up to sandwich the wire in place. Its a sort of vise. Super easy to assemble and disassemble, but also super easy to screw up the wire positions. So before proceeding any further, get a sharpie (your breaker is off right?) and label the wire positions.
Two seconds now will mean no sparks later, and you really don't want to fry the board in your new dryer. With that done, get out a red Robertson screwdriver and loosen - don't remove - all the screws. The wires will come free as teh screws are loosened, and you will be left with the box in one hand and outlet in the other. Put the outlet someplace safe, and repeat teh procedure with the ground screw and the clamp on the side of the outlet box. Save them if they are useful. If the previous owner used woodscrews and stripped the threads on your box, toss it out. With vigour. Curse you, previous owner!
On Junction Boxes
Back when I worked in hardware stores as a kid, the odd time someone would come by and unwrap a mystery you never knew existed. Here goes... stuff you didn't know about electric boxes.
For the dryer I got a common square junction box. Its a pretty boring thing. You've seen dozens of them. But look closely at the sides...
|Free Mount Side|
|Drywall mount side|
On one side of the box, the screw holes are halfway back in the box. This side of the junction box is what I call the "Free mount side" you can mount this box anywhere and line it up with anything. It has no locked position.
The opposite side of the box has a pair of little tabs and the screw holes are at the bottom of the box. This is the drywall mount side. If you bend out the tabs and rest them on a drywall stud, the space from the tabs to the top of the box will exactly equal the thickness of a sheet of drywall. (Be amazed now) and you will have 4 drill holes instead of 2. (Be even more amazed)
|My camera refused to focus on the box. Oh well.|
Now that the tabs define which side of the box will be against a stud, we can go ahead and knock out one of the knockouts on the other side to accommodate our wire.
This is also a good time to talk about the wire clamp. The wire clamp in the top right corner of the box does two things. First and most importantly, it prevents teh wire from being cut by the sharp edge of the box. Second, it prevents teh wire from being pulled or chafing. It does these things by going arounds the wire, and then inside the knockout of the box. As you tighten the screw on the clamp, it will press down on the wire, expanding the outer ring of the clam, and holding itself against teh box. If you can move the clamp around, its not working right. Especially in a laundry room where there is a lof of vibration, you want to get this right - otherwise one day you will be surprised by magic smoke coming out of your wires.
At this point the electric is 'roughed in' If you paid an electrician to rough in a dryer hookup, this is what you would have (minus the markings on the plug)
With the electric roughed in, I could switch trades and put away the electrician tools to take out the drywall tools. I hate drywalling.
Before I actually start doing drywall, I want to talk cutting tools. First a drywall saw.
This is one of my drywall saws. I think I have about 3 of them. They come and go. I don't pay them much attention. You can pick them up for a couple dollars and all seem to work about as well as any other. Drywall saws have pointy tips and are great for stabbing into a sheet of drywall to cut a hole in the middle of it. Because they are so thin, you can cut tight circles with them. I used one of these to cut out the tube lights holes in the dining room ceiling. The trouble with these saws is that they tear aggressively at the paper backing on drywall and make a big mess of dust. For rough work in spots that will be hidden, they are a great tool.
Another important tool to have is a sharp utility knife. This one from sears has been with me for years.
Right now it has a hook blade in it from working on the roof. The nice thing about these knives is that the blades in them are interchangeable - and they have on-board storage for spare blades. Often they come pre-loaded with a half dozen spare blades.
For a blade change, you just undo the centre screw, take it apart, and swap out the blades.
This one was left out when I did the roof and all the blades got rusty - but the knife is still fine.
Cutting drywall with one of these is super easy - you just mark a line and score it with the knife...
The with a quick snap, fold the drywall to make a book, and use the knife to score up the paper.
The drywall will break where the knife cut as long as you are mostly in a straight line. The edge of the drywall will be a little jagged though, so its a good idea to 'shave' along the rough edges after cutting. I have a drywall rasp for that, but a small job like this didn't make it worthwhile to dig it out, so I just ran the blade along the edge to smooth it out.
A few screws, and we're ready for tape and mud... But wait - a test of the dryer cord isn't looking good. It still won't reach! (Insert swear words here)
Luckily I hadn't cut the excess wire to the junction box. I used the drywall saw to cut a hole in the wall and move the box up the stud bay...(Those are the drum stabilizers in the bag taped to the wall - won't lose them that way).
And used the old plug with the marks from when I disconnected everything to get it all wired up. It fits good!
The drywall patch is simpler now too! I just used the offcut from the first patch, and with a little trim, I had a good fit.
Magic with mud, and its looking good. After this I was able to hook up the dryer vent and Momma got started on laundry - the new machines are much quieter, I think we'll like them! Tomorrow I'll sand and finish mudding but I need this first coat to dry. Heat from the dryer should help.
For my next job, I need to build a cabinet to hide the laundry venting and to allow Momma a spot to put her laundry baskets - these new machines are a lot bigger than the old ones and we lost all our storage!
