comment Water softener brine tank into floor/ground?
I've seen softeners where the mineral tank is actually inside the brine tank, with the filter head sticking up above, and the brine tank's cover hides the whole thing. They're pretty compact (the size of a large brine tank), so that may be an option for you -- if you can find one. Unfortunately, I can't find any reliable links. There may be a name for them that I'm unaware of. I've personally only ever seen maybe 2 or 3 out of hundreds of softeners I've serviced or installed, so it's also possible they're simply obsolete or extinct.

comment Water softener brine tank into floor/ground?
I've never seen such a thing. I can think of a few problems though. I'd be worried about dirt, insects and rodents being able to get into it. It would also be very difficult to clean, if that ever did happen. It would make it difficult to tell if it was working correctly, not to mention how much salt was in it. There'd be no real place for the overflow valve to go when the float valve eventually fails, and again, you'd maybe not even notice. Given you need fairly regular access to it (eg: you can't really put anything on top of it anyway), what's the motivation for putting it under the slab?

comment Is this wiring suitable suitable for 3-way Z-Wave switches?
I guess you actually have either option; it depends on your purpose for adding controls in the first place, and if you'd like dimming capability or to be able to control other z-wave devices.

comment Can a 15 amp electrical switch be used to replace a push button switch for garage door opener?
Some newer openers don't use simple push-buttons, they actually send a signal on the line. If your switch now looks like it has a circuit board inside (or motion detector/lcd/etc) it is likely that it'll only work with the manufacturer's specialized switches.

comment Correct wiring of float switch into two pole contactor for well pump
Per Tester101's comment, why are you using a contactor at all? What type and size of well pump (submersible, jet pump) and is it currently hard-wired or plugged-in? Also, what is the model of the float switch you have? Hopefully it's a "PMU" model (pump-up), but they also have versions with and without plugs (which is why I ask). All of these will potentially dictate the best way to wire this up.

comment Electrical panel main breaker
Originally most of the power generated in Canada was actually hydroelectric (Niagara Falls being a huge source), although now hydroelectric accounts for ~19% of Ontario's power, and most (58%) comes from nuclear. Here in Ontario the company that delivered power was for many years Ontario Hydro, and is now Hydro One or one of the local "<City> Hydro's" -- hence still being shortened to "hydro".

comment Does the head of a pump depend on pipe diameter?
Diameter affects friction loss, which affects Total Dynamic Head, which is why I explained both. Does pipe diameter affect static lift head? No.

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.
