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 get my garage door open without prying it with a hanger?
You won't be able to 'hotwire' the keypad at all. Most keypads are wireless (since you're talking about programming, I'll assume this is brand new), and are all digital. They have to send a special unique code (an encrypted "open" command probably - I'm not sure exactly how they do it), and the only way they'll send that code is if you enter the right sequence of buttons. An un-programmed keypad won't even know what command it should send, even if you could somehow 'trick' it into sending it (which you can't anyway). Good for protecting from intruders, but not your current situation :)

revised What does it mean when a drill says it is 3/8", and where do I get bits and extensions for it?
that is a 3/8" drill, and adjusted title to be more generic

comment wiring switch loop properly
Non-contact voltage detectors can be misleading, as induced current running from nearby wires can cause a false positive. Does the wire 'bringing the power' come from the panel, or some other switch/outlet? Step one is to ensure that has 120V hot on the black conductor, neutral on white, and a grounded bare wire. Using a multi-meter is a good way to be certain things are correct: you should measure 120V hot-to-ground, 120V hot-to-neutral, and 0V neutral-to-ground.

comment Enclosure for whole house water filter
It sounds like you have a city water supply -- so what type of filters are you using? If you need sediment filters, the city is not doing their job at all. If you are using activated carbon (for taste), you're going to end up going through cartridges rather quickly, with the water for your washing machine, dishwasher, shower, and toilets all being filtered. Most people don't really care what their toilet water tastes like, but I digress.

What do you mean by an 'energized white wire'? How did you determine this?

comment How to fix leak coming from pressure gauge on water tank?
@mbeckish I was merely reacting to your suggestion to just replace them next without further troubleshooting/diagnosis.

comment How to fix leak coming from pressure gauge on water tank?
@mbeckish No, if the new valve leaks, either there is something else very wrong (eg: the pressure is actually really high and the pressure gauge is broken) or there is actually a leak from somewhere else that dripping onto the relief valve and just making it appear that's where the leak is. Don't just blindly replace other components.

comment How can I remove a non-load bearing wall in my basement?
Your answer seems to assume that this is a very old house.. I'm not sure how you made the jump to assuming that it's old lumber, or that if there are three rooms the wall is not load bearing. In Canada at least, it's very rare for there to be any load bearing walls in the basement: any house built in the past 40 years likely has jack posts and beams (except perhaps for the walls supporting the stairs).

comment Could treated water backflow into my RO system?
It doesn't sound likely it would backflow, because there would be pressure on it at all times. Don't have time for a full answer right now but -- ack, chlorination in a home system. When chlorine interacts with organic particles it can form byproducts that are linked to cancer (most notably THM): some futher info here. There's also dealing with a dangerous chemical. Anyway, you don't drink the water, which is good, but thought I'd post anyway for anyone else that comes across this.

comment What should I use to hang a coat hook on a brick wall?
You'd also need fewer fasteners going into the brick/mortar.

comment Can I connect all of my LED strips to a single power supply?
Either works. It really just depends on the exact situation: you just have to balance the size/length/complexity of wiring, cost of power supplies, and availability of space.

comment What is the most energy efficient way to heat a converted garage space?
Careful with gas -- International Residential Code (IRC) G2406.2 (303.3) doesn't allow gas burning appliances in bedrooms unless it is direct-vent type or gets its combustion air from the outside and is separated by a weather-stripped door.

comment Can I connect all of my LED strips to a single power supply?
Sorry, I wrote that for 5050-style LEDs, not individually addressable with a data bus. Updated -- and yes, you can daisy chain data wire and have separate power.

comment How to stop cold drafts caused by a warped door sill?
Using a door sweep (which attaches to the door itself) certainly would not hurt, but if the sill/threshold is actually warped, @bobfandango's answer also definitely applies. Personally I would probably go towards a metal door sweep that screws on rather than the adhesive/plastic one you linked, but that's just me.

comment concrete and slate roof has started to leak
This site works best with a specific question. If you're simply looking for alternatives (and especially if you are not doing the work yourself) it's best to get some other companies in your area to come give you quotes/options. If you want to ask how you can fix this roof yourself, we'd need many more details (and pictures) -- though considering you've already said it's leaking in multiple places, and you've already been quoted on doing a complete replacement, most likely replacing it is the best option. As with any project, be sure to get quotes from more than one contractor.
