comment Where should my furnace filter go in a Lennox G40UHX series furnace?
@Tester101 Thanks. Updated with what I think was the original one, it's the only furnace filter type thing in my old picasaweb albums.

comment Need help designing a circuit layout and wiring diagram for a garage
You should also take into consideration that NEC 225.31 requires a disconnecting means for power in separate buildings, either on or inside the actual structure. This commonly is a sub-panel but there are other ways to satisfy the requirement. This means you can't just branch from the line you ran -- it must go to a disconnect first, and then you can branch to the outlets/lights.

comment In electrical terms, what is the definition of a “disconnect”?
Individual breakers don't necessarily satisfy requirements: apparently some inspectors will allow it, others won't -- so check with them. Having a main breaker in your subpanel does definitely satisfy the requirement though. And the good news is that your local big box store, you're likely to find a small main panel including main breaker and a couple branch circuit breakers for cheaper than just a plain subpanel.

comment What's Behind my Drywall
Is this an interior or exterior wall? Could be also be cloth-covered electrical wire (used in the mid-1900's). Normally, wire shouldn't be close enough to drywall to hit when hanging pictures, but you never know. A stud finder with electrical detection or a non-contact voltage detector will probably help you out here (also, obviously, please stop poking/digging at it until you know what it is).

comment How do I put a proper foundation under a sunroom that is already built?
Is it actually a "3 season room"? Normally those would not be suitable for winter: Normally there is an exterior-rated door separating from the rest of the house, and no connection to the home's HVAC system. They may have no or very little insulation. Is there a door? HVAC vents or other heating? Can you see insulation (or lack of insulation) in the floor, roof or walls? What type of windows and doors are on the room? Pictures may help a lot..

comment How would I connect power from an emergency security flood light fixture?
What exactly are you trying to do, and hook up? Also please note that security lighting is considered a life safety device, and is covered by some fire and building codes -- notably NFPA 101 and the IBC (international building code) -- and tampering with this equipment may result in prosecution depending on where you live. "Any person(s) found tampering with, willfully undermining, or who negligently fails to maintain fire or life safety equipment may be subject to disciplinary and/or criminal proceedings as outlined in sections 430 and 433 to 436 of the Criminal Code of Canada."

comment What's the best way of replacing a plug or switch in a house with aluminum wiring?
@kevinmicke I find it hard to take the CPSC document too seriously when it doesn't even mention anti-oxidant paste at all. Contrast that to what the ESA says, which I added to my answer.

comment Why does my water softener make the water smell like Iron and taste like salt?
What model softener head? When you say the level is now 8, are you referring to a setting on the softener or did you measure it? If you haven't measured it, that is a good starting point, and you need to measure both before and after the softener. (You can buy hardness test kits online and in many stores -- the type with test strips are simple to use and reasonably accurate). Any other info you can provide about settings on the softener would also be useful.

comment Water pump keeps running, there is low pressure
If you have valves shut off to the house, does the pump eventually stop, and at what pressure? If you then open a tap, at what pressure does the pump turn on? If you turn off the pump and open a tap to let the tank drain, what is the pressure reading from the tank? I am assuming since this is a 3-year old tank, that you have a bladder-type pressure tank? Submersible or jet pump?

comment Does PEX require home runs?
FWIW, I've seen far more trunk-and-branch installs than home-run installs. My current house has a couple fixtures sharing a 1/2" line, and those do compete for pressure, but the ones on the 3/4" trunk don't cause noticeable problems. I do plan on fixing it at some point, but at least the builder saved $10 on that 10 feet of 3/4" PEX and fittings...

comment Does PEX require home runs?
I've seen PEX blow apart when you turn on the water and forgot to crimp something, but I've never seen PEX leak -- either with the rings or with the clamps. I've worked on hundreds of water treatment systems done with PEX, and I also personally know of many houses (including my current ~10 year old house) that have no issues.

comment Does one wall socket share power between both ac plugs?
You don't require nor should you have a "separate ground" for a split outlet. In fact I've never seen an outlet that has the ability to have separate grounds. There are other specific requirements around how to run actual wiring for this, which may mean you end up running two ground conductors because you have two separate wires or conduits, but they'd end up being connected (on both ends) anyway.
