Started working for my dad's water treatment company in my teens, installing and repairing pumps and water treatment systems. Later worked on automated monitoring and control systems for small water treatment systems, including PLC programming, panel design, systems integration, and designing and building our own SCADA software package. Currently employed as a senior software architect at a print software company.

Renovations around my houses have included installing complete bathrooms (both reno and adding new), complete basement gut and reno, and all types of electrical, plumbing, and ethernet/video/audio cabling. Also have a particular interest in home automation -- my current house has several rooms controlled using Insteon gear.

comment What should I consider regarding LAN wiring before building a house?
If it's not a great expense, sure, but personally I don't advise people to try to beat technology. Too many times, it rapidly shifts: for example, a few years ago HDMI didn't exist, now it's the only thing to use for video. Yes, 10 gigabit will trickle down, but let me put it this way: an uncompressed 1080p movie can be streamed using around 25 megabits. That means you can stream roughly 40 1080p movies over a single gigabit cable at the same time. It's a time/money/technology trade-off: Will 10 gigabit over Cat7/whatever become necessary/useful before Cat7 is replaced and becomes obsolete?

@Mario was actually an old cabinet that was left there, just happened to be a perfect size.

comment Why does my sink supply shutoff valve spray water when I close it?
+1 for using a ball valve. They are so much more reliable than any other valves.

comment How to deliver hot water from bathroom to kitchen
Are they running entirely inside, or do they go outside at all? What is the temperature range of the ambient air? Are you trying to conceal the pipes in walls? Typically 3/4" copper or pex would be used, are either of those a problem?

comment How do I troubleshoot power receptacles?
Why would you unwire to test this? I would start with a multimeter just checking between hot/neutral, hot/ground, and neutral/ground without even taking the face plate off. If that works, whatever you're plugging in is probably broken. If not, check for obvious broken or bad connection, and THEN disconnect the receptacle to test.

comment How should I install a signal cable duct from new home office to a wiring closet?
Tip: run conduit, but run your current wires outside of the conduit while you can. If you ever want to add wires, the conduit is there (and empty). The more wires in the conduit, the more of pain it is to run new wires. A lot of the wiring (eg, Cat5e/Cat6) is likely to remain useful for a long time anyway, and you're probably not likely to have a reason to want to remove some particular wire if it's not in the way.

comment How to best insulate an exposed waterpipe during the cold season
Why do you have this pipe? What is it for? Picture? Where do you live? Very strange that anyone would install a pipe outside in a way that it would freeze. Usually exterior pipes have a shut-off somewhere so during the winter they can be drained, and they simply aren't used.

comment Do any ultra quiet ceiling fans that have no motor hum exist?
I'd also recommend a fan with a timer on it. Some of the models with remotes have timers, and if you're hardwiring you can use an in-wall countdown timer. Personally I like the fan on while falling asleep, but hate it in the morning when it's colder (or the cold fan wakes me up too early), so the timer that shuts it off sometime after I fall asleep is perfect.

comment Can I use a transfer panel with something other than a generator?
Since you're using dimmers as opposed to newer LED stuff (which many times has its own DMX control built-in), it means you're using stage lighting fixtures are likely 500 to 1000 watts each. I personally would not trust running lighting through old 40's wiring. I used to work on this stuff when I was in high school, and even though the stage was pre-wired (MANY years prior) we just ran our own cords and/or truss-mounted dimmers because the built-in wiring was unreliable: on one occasion a circuit actually shorted out putting on a very nice display of sparks, and we never touched it again.

comment Can I use a transfer panel with something other than a generator?
I would recommend against doing things this way for a whole ton of reasons. Usually your plugs are up high because that's where your lights are, otherwise you have cords running all over the place. Depending on the situation, there are also small DMX dimmer packs that can be installed on trusses right beside the lighting (so you run constant power + DMX signal). I would not want to introduce even the possibility of someone plugging some (broken?) piece of electronics in and damaging the dimmer. The regular mains outlets and dimmer-controlled lighting circuits should all be totally separate.

comment How to secure a doggy door from intruders?
@Steven: No. Motion sensors have two sets of "beams" they send out that are alternating (like this), and basically the alarm goes off only if both beams are tripped: they're spaced so that a dog or cat will never cross both zones, while a human will. Pet immune detectors are rated by the size of animal, and this dictates the beam spacing (higher the weight rating, the farther apart the beams are, and the more movement it takes to set it off).

comment Is temporarily reducing the water supply line an option when installing a water softener?
The softener will work ok, but when it regenerates and backwashes, it likely won't have enough water to be (as) effective. Over time you'll reduce the effectiveness of the softener itself, and probably have to prematurely rebed the softener (change all the media inside -- normally this is done every 10 years). You can use the smaller hose, but definitely fix it properly ASAP.

Did you not have it connected to the softener while gluing it together, so that it was not possible for it to not be perfect?
