comment Would you ever wire white and ground together?
Be sure to check that both ground and neutral are okay. I would really want to find the other end of this wire to see how it's connected, as this looks very strange. I can't think of a reason to do this (considering there are no downstream circuits) aside from maybe a broken wire? If this is done this way, there are likely other strange/wrong things and so you should not make any assumptions about anything you're working on.

comment How do I wire a switch/receptacle combination?
I'm not saying one or the other is better; was just suggesting an alternative. The "better" one for you is probably the one that causes the least damage (and of course meets code).

comment Can my apartment's electricity harm my computer? Is there an easy way to test the electricity?
Note, there are many types of UPSes, not all of which will solve problem. The cheapest "standby" type simply switch to battery after mains is lost, but otherwise pass it through. You can still have problems on this. The more expensive "online" UPSes always run from battery giving a very clean and steady output, and simultaneously charge the battery while mains is available. However, most UPSes have decent surge protectors built-in, which you should have on really all sensitive electronics (not just computers).

Not related to fixing the root of your problem, but a couple comments: a UPS with AVR (auto voltage regulation) will help smooth the power. Not all computer/laptop power supplies are created equal. The cheap supplies are cheap for a reason, and don't handle poor line conditions well. The more expensive supplies have better circuitry that can handle varying input conditions a bit better and produce more reliable output.

comment Plywood floor gets inexplicably wet, what could possibly be the cause?
It's not necessarily directly above. Since you have no explanation either way, it'll at least point you in the right direction, or rule something out. You can do the same on the bottom. Is any insulation wet? Pictures may help. Does it happen every day? Can you figure out time of day?

comment What is the best way to incrementally finish an unfinished basement?
I disagree with the need to use PT wood. In my basement, I didn't use the styrofoam, but instead wrapped the bottom of sill plate in 12" wide 6mil vapour barrier. Even with just styrofoam it's probably enough. Also, there should be a gap between the studs and cement walls - this prevents moisture and water from getting on them, as well as gives you a thermal break. IMHO PT is just overkill in this situation, and doesn't really provide any real value if everything else is done properly.

comment How to patch this PVC elbow connection?
You're sure that's PVC and not polyethylene? Poly is flexible, and is typically used for all the source-side well pump stuff. It's hard to tell from your picture, but is there any more to the pipe coming out of the ground?

You should try some plastic (eg 6 mil vapour barrier) over top of the plywood, taped down, which will at least confirm if it's coming from above or below. An intermittent problem that causes a visible pool of water from spraying underneath the plywood seems fishy to me; my gut says it really does sound like a leak from above.

comment What should I do with a 3-way light switch that is no longer needed?
What are the cables coming into each of the switches, what color wires in each, and where do they go (if you know)? There are a few different ways to wire 3-way switches, so the best answer depends on how yours is configured.

comment How can I wire a panel heater?
One consideration: it's not CE/UL/CSA/whatever-approved to have a plug, and so if a fire was ever [suspected to be] caused by this, your insurance company may not have to pay the claim.

comment Damp proofing/tanking a basement
How much water is coming in? Is there an actual crack or hole where it's coming in? Is it humidity, or a full out leak? Does it happen when/after it rains, only during spring run-off, or all the time?

comment How do I “fix” a bad sweat (solder) joint?
Agree with using MAPP. Also, the joints need to be cleaned well.. and your flux (and brush) should be clean too (eg. it's pointless to clean everything and then use a dirty brush and/or dirty flux). The fitting should be hot enough that when you touch the solder to the joint, it "sucks" it in and basically goes all the way around (sometimes you have to touch it to the opposite side to ensure it's all sealed). If you have water in the joint, this won't happen, and you won't get a good joint.
