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.

comment Why would a light switch be wired with the neutral wire?
Agree, don't make assumptions (especially if you've ever found anything else not to code in the house). However in this case, when there are only two conductors in the box, both going to the switch, and the switch is working to turn the light on and off, they must both be hot (or both neutral, if someone really got things messed up elsewhere). Either way, not possible to install a "smart" switch that requires hot+neutral.

comment What is this part of the well pump/tank called, and how can I fix it?
There are many variations of jet pump configurations (at least I assume this is a jet pump, since you had to prime it), and I am really unsure from your description what part you're talking about. Can you take a picture and point out exactly where the leak is coming from (at least as best as you can identify)?

comment Retrofitting a remote opener into a garage-gate motor
Have you looked for an off-the-shelf solution (eg, from the manufacturer)? What are "the three remote buttons in our cars" .. do you mean built-in, "Homelink" (or similar) buttons? Are the buttons high or low voltage? Does the gate stop on its own when full opened/closed? What happens if you push close while it's already closed (and open when already open)? DIY - You might be able to retrofit something with a couple 'add-on' remote adapters and some relays (using two buttons, one for open, one for close).. or you might need something more complex (with a microcontroller) to have one-button.

comment 20amp ac unit shut off all my power. is a 110 unit lower?
Amps (15, 20, 30, 40 or 50) is amperage or current; volts (110/115/120 or 220/230/240) is voltage. If everything is to code, you can identify the circuit type based on the outlet. Note also that the maximum current is for the entire circuit, so if there are other appliances using power from other outlets on the same circuit, you'll have to take that into account. You can either get a unit that works with the circuit and plug you have, or get an electrician to add a new circuit with the plug you need for the unit.

comment 3" conduit with many bends - is it worth to build it?
If you open things enough to run conduit, don't put the cables you're running NOW in it -- leave them strapped to the outside. Cat5e, RG6 and speaker cables have been and will continue to be useful for years. The conduit is for new cables you don't know you need (or don't exist) yet. You may also want mechanical protection, but that's probably better done with either a separate conduit (where needed) and/or strategically-placed nail plates.
