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 How do I lubricate plastic rollers for sliding closet doors?
It's been well over a year, no problems at all. A few days ago actually I gave them a quick spray but only because I had a squeak in a door (not these ones) and so went around and lubricated all the hinges and such.

comment Where can I find unusual L-shaped brackets?
I have to say I have no clue what you are trying to do from reading your question. What type of windows (casement, double-hung, sliding, etc)? Pretty much all windows have an interior and an exterior side, and whether the screen is on the inside or outside depends on the style of window -- are you saying the window is installed backwards (eg, the exterior side is facing inside)? A picture would go a long way here.

comment What can I do to prevent injuries from the corners of a wooden deck?
Is it feasible to round or cut off the corners again? A picture (preferably with measurements as well) will help someone answer, as it's not clear how much room you have to work with.

comment Is there any way I can reclaim this space and still safely support the front steps?
In addition to the overview pic, a floor plan/diagram that shows the joists, support structures (at least that you know about) and dimensions would be useful.

comment How can I move a non load bearing wood frame wall?
You don't need PT wood. Put a foam sill gasket underneath or wrap the bottom plate in 6-mil plastic. Untreated wood will rot from the water whereas PT won't but I've gotta think that preventing moisture from touching the wood at all is even better.

comment What are my options for multi-room audio?
There are many ways to do this, including several commercial systems that have many of the features you're asking for. Do you have a budget in mind? Sonos is actually fairly cheap per-room compared to some of the systems out there..

comment How do I size this wall to make tiles look right?
I found the same, and I'm guessing the 12" tiles are just under because then you have 1/4" grout lines adding up to the full 12" spacing (center-to-center).

comment What information do I need to size a sawn or hewn beam?
One of the challenges of real timber is that it's not uniform, and so one particular beam may have weak spots, whereas an engineered beam is designed to be uniform. I am not sure of the cost comparison, but you can get faux coverings (example) that will allow you to install an engineered beam and then clad it so it looks like it's hand hewn or whatever.

comment How to keep two water tanks have maintain the same water level?
Are these are tanks fed by a well or some other source, or hot water tanks? What material are the tanks made from? How do you get water out of the tanks now?

comment How can I build a wall mounted adjustable height desk?
Any limitations? Can the desk be adjusted electrically/hydraulically, or does it have to be manual? How easy does it need to be to adjust? Does it need to stay flat and/or have stuff on it while being adjusted? How much weight does it need to hold? What are the dimensions? Does it need to be made of some particular material? Can you give more clarity on the height adjustment needed? Are you saying you want to be able to use a treadmill underneath the desk, so the desk needs to raise up so the bottom is 7' from the ground??

comment Why are some submersible well pumps wired with solid and others stranded?
Water holding tank?? This sounds like a dug well, or a drilled well in a well pit. You don't want surface water to infiltrate drilled wells, which is why we no longer use well pits. The WellAware site has a lot of good info on this stuff -- unrelated to the original question, but you may want to check it out. Floats in dug wells are rare, in my experience, and if it's not a dug well it's a warning flag something was done wrong.

comment Can I level floorboards with metal or rubber washers?
What's underneath now -- just the joists, or is there some other subfloor or slab?

comment Can I share a 240V outlet between two devices?
I like this but it's not a "power strip" (which made me think of a power bar -- something that would allow both connections at once) so much as an adapter. The downside of this is it requires plugging and unplugging a fairly large connector which is not necessarily designed to be plugged/unplugged that many times. Due to the size, there is also a higher risk of shock if you touch one of the large prongs. For this reason, @ppumpkin's solution is safer, but it does really depend on how often the plug is being swapped.

comment Does anyone make a gfci switch/outlet combo that includes a nightlight?
Agree with @BMitch -- a GFCI breaker comes to mind as a good option.

comment Why are some submersible well pumps wired with solid and others stranded?
In my opinion, as long as you are using submersible pump wire and have it secured properly, you're okay. Most common is stranded submersible pump wire, but they also make stuff that looks the same but is solid (it's just less flexible). Also, any connections in or around the well should be done with heat-shrink connections, I've seen wire nuts used at the top of the well and that's just a safety hazard if they fall apart or get wet.

comment Why are some submersible well pumps wired with solid and others stranded?
I have worked on many wells, and I can picture two where solid wire was used and we were replacing it: in one case, it was brittle and had snapped, and in the other it had rubbed against the exterior of the well and broken the line. In at least the second case, the wire may have worked if it was secured to the pipe (taped every few feet): every time the pump starts up, it spins the whole thing probably 90 degrees, so if you leave the wire hanging there over time it'll damage it. Stranded wire is probably less affected by this, but still can have the same problems.

The pressure switch is outside in the well? What is the climate? I would definitely be worried about it freezing..

comment Can I use old abandoned iron pipe as electrical conduit?
BX (armoured) cable would probably be simpler than running another conduit inside, although I am still not sure if this would meet code.

comment Do you know any switches which turns on/off based on day light?
Are you trying to control the light based on inside or outside levels? Is the light inside or outside? Do you need actual light, or would a celestial timer work (knows what time it gets dark based on your location and day of year)? I have a celestial timer on my front porch light that works great -- turns on at dusk, and off at 11pm.

comment Is there risk in getting a larger pressure tank for my well pump?
@ChrisCudmore Good point, though it's slightly more complicated (of course). The well itself has a capacity, which depends largely on the depth, and so long as you don't use up that capacity before it recovers you're okay. As you point out though, if you use up the capacity in a single cycle you'll have a problem, but if you're doing that you're using more water than the well can handle anyway and should at the least have low-level protection (eg a low-pressure shut-off switch, or a controller like a Pumptec), and could possibly consider an entire low-yield system (involves a large cistern).
