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 Plywood floor gets inexplicably wet, what could possibly be the cause?
It's not necessarily directly above. Since you have no explanation either way, it'll at least point you in the right direction, or rule something out. You can do the same on the bottom. Is any insulation wet? Pictures may help. Does it happen every day? Can you figure out time of day?

comment What is the best way to incrementally finish an unfinished basement?
I disagree with the need to use PT wood. In my basement, I didn't use the styrofoam, but instead wrapped the bottom of sill plate in 12" wide 6mil vapour barrier. Even with just styrofoam it's probably enough. Also, there should be a gap between the studs and cement walls - this prevents moisture and water from getting on them, as well as gives you a thermal break. IMHO PT is just overkill in this situation, and doesn't really provide any real value if everything else is done properly.

comment How to patch this PVC elbow connection?
You're sure that's PVC and not polyethylene? Poly is flexible, and is typically used for all the source-side well pump stuff. It's hard to tell from your picture, but is there any more to the pipe coming out of the ground?

comment Plywood floor gets inexplicably wet, what could possibly be the cause?
You should try some plastic (eg 6 mil vapour barrier) over top of the plywood, taped down, which will at least confirm if it's coming from above or below. An intermittent problem that causes a visible pool of water from spraying underneath the plywood seems fishy to me; my gut says it really does sound like a leak from above.

comment What should I do with a 3-way light switch that is no longer needed?
What are the cables coming into each of the switches, what color wires in each, and where do they go (if you know)? There are a few different ways to wire 3-way switches, so the best answer depends on how yours is configured.

comment How can I wire a panel heater?
One consideration: it's not CE/UL/CSA/whatever-approved to have a plug, and so if a fire was ever [suspected to be] caused by this, your insurance company may not have to pay the claim.

comment Damp proofing/tanking a basement
How much water is coming in? Is there an actual crack or hole where it's coming in? Is it humidity, or a full out leak? Does it happen when/after it rains, only during spring run-off, or all the time?

comment How do I “fix” a bad sweat (solder) joint?
Agree with using MAPP. Also, the joints need to be cleaned well.. and your flux (and brush) should be clean too (eg. it's pointless to clean everything and then use a dirty brush and/or dirty flux). The fitting should be hot enough that when you touch the solder to the joint, it "sucks" it in and basically goes all the way around (sometimes you have to touch it to the opposite side to ensure it's all sealed). If you have water in the joint, this won't happen, and you won't get a good joint.

comment How to build a screen canvas?
Many projection screens (like this one, for example), are mounted to the ceiling, and can be pulled down (some manually, some motorized) when needed, and otherwise stay out of the way. I'm asking if that's your intent, or if you would want to build something portable, or if you'd build some kind of temporary structure with a screen on it that blocks your windows all the time, but can be disassembled/moved when you move out.

comment How to build a screen canvas?
You mention the wall has huge windows -- does that mean you're trying to build a screen that retracts? Do you have something in mind for that mechanism already?

comment What would cause a gas fired, forced water boiler to shut down?
Have you tried cleaning the flame sensor (using steel wool, or fine sandpaper)? This normally needs to be done yearly. The gas not kicking on at the right time sounds like a totally different problem, but cleaning the flame sensor is easy and cheap and will at the least rule it out.

What sort of hose or what's this for? Why is the new hose different from the old? Pictures may help
