comment Causes of hot water flashes?
First thing that comes to mind is someone or something else is using cold water (turning on a tap, for example). Have you ruled that out completely, including anything outside, humidifiers, etc? If your shower valve is a pressure-balancing or a thermal-balancing valve (which would normally prevent this situation) it could be faulty in some way.. any chance you know the type of valve on your shower?

comment Wiring a Receptacle wth USB ports
How was it previously wired? Is this a kitchen outlet? Usually the only times you'd use 3 conductor wire is if the outlet is switched or it's a kitchen split (feed by a double breaker)

comment What diameter pipe should I run from a septic pump up hill (3 meter head ) to my septic tank?
I would also think a backwater valve would be an essential backup device in this situation, though if it did ever backup, I'm not sure how you'd "reset" it for use again, as you'd have all the waste water in the uphill pipe holding it shut with nowhere to drain to. Anyone care to weigh in on this? Can a backwater valve be installed at the septic tank at the top of the hill? Quick search doesn't really find anything about this (probably because a septic tank uphill is just a Bad Idea in general..).

comment What is this gray thing thing on a main water line right after it comes into house?
Is that a tubing port on the bottom (white piece)? I've seen adapters that allow an injection line (3/8" poly tubing) to be inserted within an existing larger pipe (basically saving you from digging a trench to the well), and wondering if this is one of those. Similarly, if it's an electrical connection, it could be a heat tape connection (which are all proprietary) -- they typically have a pigtail coming off as opposed to a connection, but maybe the wire has been cut off?

And in the case of a straight 240V, the white should get marked with black tape to indicate it's hot.

comment How can I run USB to every room in the house?
If you are concerned about network security, avoid any products with "cloud" features/connectivity (or be sure to turn it off). For the most part, if you don't open firewall ports on your router, and you don't have equipment making outbound connections on its own (to a "cloud" system), there's not a lot to worry about. You can also just not connect it to the internet. Don't forget about local access: either by wifi or by some random person plugging in (though this is mostly a concern in offices where there are often active, unsecured ethernet ports in reception or meeting rooms).

comment How can I run USB to every room in the house?
You commented you want "cameras, sensors, and light controllers". Unfortunately there is no one unified system to do this today. IP Cameras are widely available, as are lighting systems (search for: Z-wave, Insteon or Zigbee). "Sensors" is a bit open-ended, but there is lots of off-the-shelf gear for monitoring server rooms, for example. A RaspberryPi or Ardunio is also a good solution to interfacing with random sensors, and both can be connected back to ethernet or wifi.

The complexity of custom code running on kit hardware to hack a protocol that's not designed for networking or distance work to network your house is going to far exceed the complexity of running an "IP stack" (which consists of .. plugging in a $50 router).

comment light and fan. together but separate
Seconded @Ecnerwal's suggestion. I have 2-5-10-15 and 5-10-15-30 minute switches on all my bathrooms, depending on if they have a shower (30m) or not (15m). Great to leave on after leaving the room if there's any steam/humidity or odors..

comment Three hot wires,1 neutral on a switch
Non-contact is great tool for general use, such as verifying a wire is not live before you cut or work near it, finding the breaker for a circuit, etc. I always have one in my tool bag if not my pocket when doing any type of reno work. However, they're not appropriate for actually doing electrical diagnostics, because they too easily give false readings. You should really get a multimeter for testing actual voltage, and at this point, knowing the voltages is the only way to help you out.

comment Three hot wires,1 neutral on a switch
What do you mean "test hot" -- how are you testing? Neutral to ground should be 0V, hot to ground and hot to neutral should be ~120V. If you are seeing different (such as non-zero voltage on neutral to ground) then something is wrong.

comment How to turn off all power to the electric panel?
Also a bit overkill, IMHO. Really, how often do you need to do work between the panel and the meter that would justify the cost of installing an extra weather- and vandal-proof switch outside? Sure it would be nice now if it was already in place, but are you planning on replacing/upgrading/moving your main panel again in the next, 5, 10, 20 years? At the end of the day, it's your money to burn, should you choose to do so.. I'm sure the electricians/suppliers/inspectors/etc won't have a problem taking it ;)

comment How to turn off all power to the electric panel?
If there is an extra switch, what do you do if you need to replace that switch? Have another switch for the switch? :) There has to be a demarcation between owner and utility at some point -- and that point is the meter.
