comment well pump keeps turning on and off every few seconds
Aside: You should really fix the electrical wire that is very incorrectly terminated in the pressure switch. It is a fire and shock hazard, not to mention violating electrical code. There should be a box connector, and the wire should not be stripped outside of the pressure switch (create a new question here if with a picture attached if you'd like more specific help on how it should be done).

comment How to pull toothbrush out of the sink?
Agreed with @Ecnerwal: if you have to cut it apart to get the toothbrush out, take the opportunity to install a new standard trap where the U-bend is easily removable.

comment How can I repair a ceiling fan that hums, but doesn't turn?
Try opening the cover and spinning the fan by hand (with it off, of course). Does it spin freely? I've never personally heard of this with bathroom fans, but there's also a chance with any electric motors there is a 'dead spot' and moving it out of the spot will let it run (until, of course, it stops in the dead spot again). May be the motor windings are wearing out, the brushes/commutator are dirty. Whether this is serviceable or not depends on the motor/fan and your skill, and of course has to be weighed against replacing.

comment Can you terminate more than one common on the furnace C terminal?
Technically speaking, if the transformer in your furnace is too small (eg: JUST big enough to power the control board, relays, and whatever else is already connected) then it's possible that the thermostat could push it over the edge, causing your furnace to not work and/or behave strangely. However, the amount of power we're talking about here is pretty small. Unless you're connecting a thermostat with a monster color touchscreen to a >=20-year-old furnace/air handler, chances are you won't have an issue.

comment How do I connect a ceiling fan without a light kit?
What wires are in the switch that control the fan, and how are they connected? Green wire in the ceiling box is throwing me off a bit, I would have guessed you have a 14/3 between the switch and fan, but that should be red, black, white, and bare copper.

comment Could wiring a dryer incorrectly cause the control board to be destroyed?
With luck, you just blew a fuse in it, but there is a definite possibility something is fried, especially if any of the magic blue smoke escaped.

comment How can I run cables along a concrete wall?
An RJ-45 crimp tool can be found online for $10-20 (though you'll spend another $10 on bad crimped ends while you learn how to use it) and once you have that, bulk cable is very cheap and you can make any length you want (plus it fits through a much smaller hole without an end on it). Alternatively, there are ethernet-over-power adapters which are a decent option if you have a dodgy wifi signal.

comment Will foam-filling this gap create problems?
6" of closed-cell spray foam is a lot. From what I understand 3-4" is more typical for getting a high R value. Though the rating is ~R6-7 per inch, the pro spray foam guys I've talked to all seem to think it's effectively a much higher R value presumably because of zero air and vapour movement. I've also been told that beyond 4", it really doesn't add much (other than cost and install time -- apparently you can only spray 1-2" before letting it cure for an hour or so, then putting the next coat on).

comment How do I replace rotten Subfloor under a supporting post
What you are suggesting is dangerous -- car jacks should not be trusted as a support: it's the reason people use jack stands when working on a car. Also, -1 because your spelling/capitalization/punctuation/grammar just make my head hurt.

comment In a multi-gang box, are neutral wires paired with specific hot wires?
@drs From your picture, it looks like a single circuit switching multiple outlets/lights. The wire at the bottom of the schematic is the feed from the panel, the other four wires are going to lights/outlets. Can you just confirm there is there a single breaker that will switch off power to this entire box, and that the existing four switches control four separate sets of lights and/or outlets?

comment Can I output video single wire RCA signal out of 3 composite ports?
I don't, sorry. I have a Roku 2 box somewhere but it only has HDMI. Maybe you can use your Receiver to downscale to 480i/composite, and output that to the projector? At least you'd only have to change inputs on your reciever, not both receiver and projector (I hate having a system that requires multiple inputs on different devices to be changed).

comment Will enclosing my porch keep my house warmer?
While cellulose for walls and foam boards for basement are examples of ways of insulating those spaces, note they are not the only way. The full explanation of different ways to insulate is beyond the scope of this question (and asked already on this site) but I just wanted to point this out as this answer's wording implies there is only the one correct method. (I agree with answer in principle, just don't like the wording).

comment How can I stop the smell from my kitchen drain?
Also occurs to me that perhaps the plumbing is incorrect (either changed by your tenant, or was always wrong but just happened to never cause a problem until now). Normally there is a P-trap that holds water, which prevents smells from coming back up. Can you post a picture that shows how all the drains are connected? We can at least spot if there is something obviously wrong (eg, garbage disposal hooked up incorrectly or missing trap, etc), to rule that out if nothing else.

comment How can I stop the smell from my kitchen drain?
Have you tried a liquid drain cleaner (just be sure to get one that says it can be used with a garbage disposal)? Next step would probably be to put a snake down and see if there is something clogging it. You could also try a plumber who will snake/inspect the drain with a camera.

comment What type of room divider should I use to convert a dining room into a bed room?
When I was in university, we used a few panels of ~2.5" XPS foam to make a partition wall so a dining room could be a bedroom. Ugly as hell, but easy, functional, cheap, and actually made a good sound insulator. True story, but I don't recommend doing this unless you're under 21 and can justify it with the fact most of your money goes to tuition and beer.

comment Extra low voltage over mains voltage circuit
Aside, forgetting any potential regulatory issues, my gut feeling as I read this is whatever you're trying to do is somewhere between "won't work" and "there is a much better way". I'll reserve final judgement until you can clarify the question..

comment Extra low voltage over mains voltage circuit
Can you clarify please? You have a regular mains (120/240V) outlet (or a circuit of outlets) and you'd like to run it at 12V? But you also want it switchable, so it can be either 12V or mains, controlled by some type of transfer switch? (What exactly are you plugging in that is okay with both 12V and mains voltage?) Is this a circuit in a residential/commercial/industrial setting (eg, a regular outlet in the wall) or something else?

comment Can a lower cabinet be used over a floor vent?
The builder of my (suburban subdivision) house did this in my master bathroom: there is a 6" hole in the floor below the cabinets, and there is a 6x2" hole with a metal vent cover over it in the toe kick. The furnace blasts air into the space below and most of it comes out the vent. This is on my to-do list of things to fix, because in the winter: 1) we can't adjust the flow of this vent and with the bathroom door closed it quickly gets to sauna-like temperatures, and: 2) it heats up the contents of that part of the cabinet enough that my wife can't store any makeup/mouthwash/soap/etc there.

comment If flame sensor will affect Motor assembly's functionality of furnace? How does that work?
You should also have at least one CO detector in your house, which will alert you to any CO. In many places, this is required by law if you have a fuel-burning appliance and/or an attached garage. Usually this should be adjacent to any bedrooms.

comment Well pump stops working after 30 minutes
@Zhentar: That's a potential fix, but definitely not an 'ultimate' one. You may have the same yield, especially if the new well is in the same aquifer. You can of course go deeper, but then you also have the risk of running into salt or other conditions that require additional treatment ($$) where it would have been cheaper to just install the cistern, or still not even finding any more water -- you still have to pay the driller for how deep they go, regardless if there's (good) water there or not.
