comment How can I power multiple raspberry pi around the house?
One of the benefits of actual PoE (802.3af/at) is that it doesn't send power to a non-PoE device. If someone plugs a non-PoE device into your DIY injector, it may do nothing, or it may fry it. Also, tip on pricing: you don't have to go 100% PoE. In my house, for example, I have a main gigabit switch, then a separate 8-port 10Mbps PoE switch for phones/cameras. The phones, cameras and raspberry PI's don't have or need gigabit, so why pay the premium?

comment How should I hang racks from the garage ceiling with trusses?
How long is the total span of the joists, and how far away from the nearest support are you planning to hang the racks? I would be less worried about the lag bolts than about the joist itself; a 2x4 on its flat side has considerably less load capacity than on its edge. The danger here is not just the rack falling down, but part of the structure of the garage itself.

comment How can I add a C wire for a new WiFi thermostat?
"two of the wires go to a humidifier thermostat (blue and red in c slot)" -- Are these the same or different than the blue and red wires on the thermostat from your first picture? It does look like the yellow is currently connected on the control board -- what terminal is it connected to? Are you absolutely certain of what goes to the thermostat vs anything else (humidifier, A/C, etc)? Agree with Tester101 -- it would be helpful if you could upload a bigger photo, with terminal labels visible (or labelled) and wires labelled.

comment Should I lock the door between my garage and my house?
Samy Kamkar (same guy that did the fixed-code opener) also developed a device called the RollJam that can intercept rolling codes, which was presented at DefCon 2015. It's a bit more involved to actually exploit, but it's doable.

comment Can I tap into the kitchen / dishwasher drain pipe with my washing machine?
You should add reference to vent requirements, which is generally the biggest issue with "tapping into" another drain line. The diagram shows "no other drains" on what is actually the vent pipe, but doesn't label it as such nor show the minimum distance requirements to the p-trap. Without proper venting, aside from not draining correctly, water in the trap can get siphoned out, which then allows sewer gas into the house.

Why is it you would want to use a smaller size?

comment How can I stop the hose from the pump to the filter from leaking?
If the hose is clamping onto a barbed fitting, make sure there are no cuts or nicks in the barbs. It should also be pretty tough to push on (eg, you often need to use a torch to heat the hose slightly). What type of hose? What type of clamps? Pictures can help a lot.

comment Fixtures will not run hot water unless another fixture is on
Do you have your own water heater, and if so, what type? If not, where does the hot come into the apartment? There should be a shut off valve.. Can you try turning off cold and see if hot works then? Also check if there is anything coming out off cold taps (indicating cross-connection), as well as same thing with main hot turned off.

comment Bathroom light switch
@mjohns Well, there are some plastic boxes that do as well (usually with a metal strip that connects to the screws the fixture attaches to). Basically if there is a ground screw on the box, it must be connected to ground. The OP doesn't understand how to connect a pigtail, so the diagram's assumption that it's a plastic box would, in the worst case, guide someone to a dangerous situation with an ungrounded box.

If you want further and more specific guidance, take a picture or draw a diagram that shows the current wiring.

The ground must also connected be to the receptacle box, which is not shown in this illustration.

comment Moving kitchen into dining room
What is below this -- do you have access to pipes underneath? Have you considered removing the wall between kitchen and dining room? If it's load-bearing you'll have to get an engineer to design a beam and a professional to install it (replacing load-bearing walls is not a DIY job); if not, it's relatively simple to remove (though you may have to relocate some electrical, plumbing and/or HVAC runs). This will give you the 'open concept' and allow you to keep most of the kitchen more or less where it is. Worth costing both options out, anyway.

comment Cloudy water with a whole house filter that was installed in 2002?
Has the softener been backwashing? Do things clear up if you manually run a backwash cycle? (Without knowing anything about it, I can't tell you exactly how to do this -- but on a mechanical unit you can turn the dial to the first step, and on a digital unit there is usually a button to start the cycle).
