comment How do I choose the correct size pump and pressure tank?
By "airbag", I presume you mean "pressure tank"? (FYI: I've never heard it referred to as "airbag", in North America at least it's called "pressure tank" or occasionally "bladder tank".) Is the pump gravity-fed from the bottom of the tank, or are you looking for a jet pump to pull through pipes that go over the top? How high is the tank? Any objection to just putting a submersible pump in the tank? (this is what we did where I used to work - more reliable, no priming, only thing it requires is access to get it in).

comment How can I add ventilation to my room?
You should give us some more context. Is this a room in a house, apartment? What is the heat source now? Does the rest of the house/building have forced air or some other type of ventilation? Did someone renovate and make this by splitting an existing room, or was it originally built without ventilation? What's the age of the building? Are you constrained to doing stuff just within your room or can you make modifications to the surrounding structure?

comment Is a ground required when replacing an old single pole single throw switch?
It seems to me this answer also talks as if the switch is not grounded at all. I've come across the following situation many times: the box is grounded, and the switch (which is mostly metal) is screwed into the box which provides a conductive path so all the metal is grounded. The newer switches add a ground screw to the metal body, so now the switch can be grounded via a dedicated ground wire IN ADDITION to the screws holding it in the box. In this situation, is it necessary, by code, to connect this ground wire? Is it different for new vs retrofit?

comment How can I repair this door and deadlock?
I saw the picture before I read your text, and my first thought was that someone tried to kick in your door. This is the trouble with hollow-core exterior doors though, in addition to the lack of insulation: they can easily be kicked in. That's why most exterior doors are solid wood or steel fiberglass.

comment Why does my ceiling fan turn itself on at night?
The switch is a remote. Find the manual, and change the codes on it - it may be done by some key sequence, or there may be jumpers on the remote and inside the fan that have to match. It seems a bit unlikely that it's interference or a signal from something your neighbours have if it happens consistently every night and at no other time of day, but it's worth a shot to start with.

comment Why does the pressure, attached to a submersible well, keep increasing?
@MichaelJ honestly, I've never looked (and I worked on water systems for a few years). It still sounds like you've screwed with the precharge, so you should follow my instructions to check and also check the operating pressure (watch the cut-in/out pressures on the gauge). Also, most plumbers know crap-all about water treatment and pressure systems, so don't rely on hope. :) Granted, I may be biased, but I've had to clean up after plumbers "fixed" treatment systems more times than I can count..

comment What goes on threads first: tape or dope?
It's not a good answer in general since it provides no reasoning or citations as to why this might be correct. Normally I would just not upvote, but answering like this is implying the original question is valid, and I don't think it is (and I'm by no means alone, judging from responses of other users and this question).

Note: A discussion on chat caused this related question to be opened: diy.stackexchange.com/questions/21117/…. FWIW, no one else had ever heard of using both.

comment What goes on threads first: tape or dope?
Use one or the other, not both. Frankly, I've never heard ANYONE suggest using both, and have never seen anyone do this, and I didn't even fathom there would be debate about this. Personally, I typically use dope for metal fittings, and tape for plastic, but it's not set in stone. Using too much tape OR dope with plastic can cause the fitting to break, and certainly that's a bigger concern if you have both.

comment What goes on threads first: tape or dope?
What?? Why? I've NEVER seen this done, and can't imagine any need to ever do this: both products have the same ultimate purpose. I typically use dope on steel and brass fittings that I'd use a a big wrench on, and tape on plastic pipes. I see no benefit whatsoever to using both, and in fact, I'd say it's more likely to cause problems than doing it properly with one or the other. I'll remove my -1 if you can update with a good rationale, but just saying to use both is bad advice in my opinion.

comment How can I install a timer with three-way switches?
Depending on what you want, the cost may vary. To have the switch OR the timer turn on the load is cheap and easy -- but it means for example, if you turn on the switch, it permanently overrides the timer. If you want to be able to remotely turn off the light when the timer turns it on, or have the timer turn it off if you've remotely turned it on, you'll need a real 3-way timer. A quick look around shows Leviton makes one that has a special "coordinating remote switch", Smarthome has some stuff that can be linked, and there are others that say they're "3 way" but I can't find manuals.

comment why won't my furnace turn off once it reaches the desired temperature
In addition to the questions above: Did the problem start happening after replacing the thermostat, or did you replace the thermostat in an attempt to fix? What kind of thermostat was there before and what did you replace it with? Were the terminals/wires labelled and are you sure you reconnected them properly? (This may not be relevant, but:) Does the problem go away if you put the old thermostat back in?

comment Is there a mechanism to prevent a door from closing violently?
Some of these also have the ability stay fully open, preventing the closer from engaging. Once you close it a bit, the closer will close it all the way.

comment What could be causing this drop in water pressure?
Is this a new problem, or has it always been this way? What size pipes do you have in the house, particularly the main branch?

comment How much weight can screws in drywall withstand?
@Gastón How do you know it's not screwed into studs, and to follow up, WHY is it not screwed into studs?? That is the correct way to mount this, and while it may "work" with some specialty drywall products, it's like arguing you don't need a hammer because your shoe can drive in nails perfectly fine if you're persistent enough.

comment What model circuit breaker is this?
Nothing is wrong with aluminium wiring, except when you treat it like copper. Everything it's connected to has to be rated as CO/ALR, including wire nuts. You also have to use anti-oxidant paste (eg, Noalox) on all stripped ends. All of the trouble with AL wiring comes from it expanding and contracting as it heats and cools, which can lead to arcing. In older homes, just like copper it can be over-loaded as they didn't build houses for all the electrical gadgets we have today, but AL is usually a size bigger (eg, 15A circuit is 12AWG AL, while normally 14AWG CO). -Former owner of house with AL

comment How to wire multiple thermostats
There are wifi-enabled thermostats that allow remote control from a computer/phone/tablet (I have a CT30 that does this). There are some that allow multiple thermostats to be linked together (eg, NEST, which also has motion sensors to automatically recognize when you're there), although this still doesn't get a multi-zone system, just a way to heat or cool the entire house from multiple locations.
