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?

I am assuming you are talking about insulating the exterior walls of the basement? Some of the answers seem to assume you're asking about insulating between the basement and upper floors, can you just clarify that?

Your answer sounds like you are talking about insulation between the basement and floor above, while the OP seems to imply the basement is not insulated at all.

comment What can be done about this unattractive dryer vent?
Make sure all your connections are screwed together (or clamped if you're using flex pipe), and taped with foil tape. If something does come apart where you can't see it, you're not likely to find that it happened unless you went looking (like you did), or the symptoms are so bad that it's a major problem (like your subfloor or joists rotting and falling apart).

comment How to disable this timer?
It also looks like there's a manual override switch in the top-right. If you want, you can leave in one or more of either the "off" or "on" tabs depending on if you want this to always be on or off -- that way, if someone (accidentally) switches this on, it'll turn off within at most 24 hours (or vice-versa).

comment Running electrical cable within dry wall
You still want to run your ethernet where it won't be damaged, the only difference is it's not going to kill someone if they do screw/drill through it.

comment How can I attach plywood to a wall without damaging the wall?
What are you using the plywood for? Is there going to be anything attached to it (how heavy?)?

comment Can I replace my ungrounded / two prong outlets, or should I have a professional do this type of a thing?
In Ontario at least, you are allowed to replace the panel in your own house yourself, however, you must get it inspected by the ESA before the power company will put the meter back in. I opted to have a licensed electrician do this for me because of the coordination involved. They also don't have all their installations inspected (only something like 1 in 10, randomly - though mine did get inspected). My electrician also had the lineman's cell number, so they were back to put the meter in almost right away when he was ready.
