comment What is the usual maximum load for drywall?
It also depends on stud spacing: with 24" spacing, the drywall won't be able to support the same load as 16" spacing. To an extent, how it's joined could play a factor. For example, if it was put up using only nails, it's going to tear off the wall at much less load than if done using screws every 12".

comment What should I consider when replacing an outlet serving two kitchen circuits?
If you do put in two outlets, you should do it so the line comes into the first GFCI (dishwasher), then the load side of that goes to the switch and second GFCI outlet for the disposal. This way, the switch is protected as well. Of course doing this depends on where the existing wiring runs (eg, does it go from the panel to the switch, or the outlet first?)

comment How is it that two breaker switches control the same things?
A non-contact voltage sensor (like this: amazon.com/Gardner-GVD-3504A-Circuit-Non-Contact-Voltage/dp/…) is a great tool to have. I have one on me every time I work on/around anything electrical, and use it even when I "know" the circuit is off.

comment Is it normal for the concrete covering my interior perimeter drain to be damp?
If possible, you could try taping some 6mil vapor barrier down over top of it. You just need a small square (maybe 1'x1') that is air tight (and don't leave a pocket of air underneath, as much as possible). If you are getting moisture up through the concrete, it will be damp underneath the plastic. If it's condensation (the humid air in your house condensing on the cold concrete) there will be condensation on the top/outside of the plastic.

comment How can I repair screws in furniture with stripped holes?
A picture of the underside of the table would help. My thoughts are going to glue, drilling new holes through the mechanism, adding cross-bracing/a new supporting structure underneath... but it's hard to really suggest something without seeing it. It's one thing to just reattach, but I'd say the fact it's broken now means you need to attach it better than it was before.

comment Is there a safe way to splice multiple lamp fixtures on the same cord?
That terminal block is definitely not appropriate - it is not designed at all to take any weight load or tension. Though the lights themselves are not very heavy, if you have several of these strung out over say, a 12' span, the weight of the cord is actually considerable. In fact, this is downright dangerous. It's line-voltage, which means if the terminal breaks or the wires come loose for any reason, there's quite possibly 120V live, stripped wire ends falling on someone's head. I'm very surprised to see a product like this being sold in North America. Is it UL/CSA/anything-approved?

comment Can a wet vac be effectively used as a pump?
I haven't ever used a shopvac that actually had this "water pump" feature, so I can't comment.

comment Can a wet vac be effectively used as a pump?
In my experience, most shop vacs -- even the most expensive "contractor-grade" ones -- will not be able to maintain the pipe full of water: you have to suck a mix of air+water or else it will just stall. A trash pump will work the best with large amounts of water (can be rented at any rental place), and a regular sump pump will be the cheapest and most effective option.

comment What is the best kind of weatherstripping (door set) to use?
Note that these are "door sets" (I guess that is the name) as opposed to door sweeps: they are mounted to the sides and top of the door frame, and seal the top and side edges around the door. I think a lot of your answer is still valid, but the stuff about dragging across carpets, for example, is only for door sweeps.

comment Is blown-in insulation appropriate for on the foundation block in a crawlspace?
Is the crawlspace conditioned (heated/cooled by your house's HVAC system)? Is it accessible via an interior door/wall to the living space of the house? Are there vents to the outside in it? What is the floor made of?

comment Is blown-in insulation appropriate for on the foundation block in a crawlspace?
Vapor barrier goes on the warm side: if you put it on the cold side, the warm inside air will condense on it, and get the insulation wet, reducing its insulation value and potentially allowing mold to grow. On the warm side, the insulation prevents the warm and cold air from meeting directly, and no condensation forms.
