comment Does it make sense for a high pressure water motor to run 24/7?
Are you sure he meant 'spinning 24/7' and not just 'powered on 24/7, but controlled via pressure switch so it intermittently turns on and off as needed to keep the system pressurized'?

comment Installing cable trunking on ceiling without damaging the ceiling paper
Wallpaper on the ceiling? Yuck, maybe it SHOULD be "accidentally damaged". :) On a serious note, I've used the 3M Command scripts and was impressed by their ability to be cleanly removed (though I removed after only a few months), but I'm not sure if it would work as well on wallpaper. I'm confident at the worst it would do the same and most likely less damage than the adhesive usually on those conduits, but you'd have to weigh that risk considering your rental agreement.

comment Networking Phones Together in Building
But I do agree, this is off-topic. @David you need a Siemens HiPath switch, and then you need to learn how to program it. You might be able to do this, or you may spend a lot more time than if you were to get a simpler system. I'd suggest you come up with criteria you need from a phone system first, and then if this system satisfies those needs you can consider using it.

comment Networking Phones Together in Building
@sr_1436048 is incorrect about needing 3 lines: You can run a PBX with 0 outside (aka PSTN aka trunk) lines if you want. The number of trunk lines dictates how many simultaneous external calls can be handled. The smaller "key system" PBXes usually have each line accessible using a button on the phone and are a bit simpler; when you get into larger scale PBXes with more than ~8 lines this becomes unmanageable and different methods are used to handle call routing and transfers.

comment Can I attach 2x4s to the studs in order to mount my TV?
Depending on the weight of the TV, you might also be able to use 1-by stock (eg, a 1x8) or even a piece of plywood on the surface. Be sure to use lag bolts still. Keep in mind that the further the TV is away from the wall, the more force it will have on the attachment -- mostly a concern if the mount is articulated. I have a couple computer monitors at home on articulated arms attached to 1-by stock on the outside of the drywall, but if I was doing say, a 50" TV on an articulated arm, I'd use a 2x4 or 2x6. Or just get a mount that was 24"+ wide.

comment How do I convert a 3-way circuit with two lights into two 3-way circuits that control each light separately?
@bib My diagrams show a couple possibilities of how it's setup NOW (as the text above them indicates), because the final wiring diagram entirely depends on existing setup. If you'd like to draw the wiring diagrams for all possible variants then post your answer and I'll upvote it :) Also if you read Andrew's replies above, he is talking about one of the lights being a light+fan combo, and actually controlling the fan separately. At this point, I don't know if he wants the two lights separate (one of the lights really being fan+light), just the fan separate, or all three separate.

comment Which cylinder door lock shield design is most secure?
Just a comment: If someone approaches a lock with a drill capable of drilling through it and has the intent of doing so, I highly doubt they'd be deterred by a hardened lock cover and simply give up. There is always a 'weakest point' in your security, and at best upgrading to a lock like this will simply shift your lock a tiny bit further away from being the weakest point. If it IS the weakest point, that probably means your house has no windows, re-enforced concrete walls and the door can withstand a battering ram. Sounds lovely.

As an alternative you could replace the existing switches with 'smart' switches or keypads (eg, Insteon, UBP or Z-wave) and install in-line modules in the fan to get independent control everywhere, without opening walls. The hardware is more expensive and it's a bit more technologically complicated, but it may work out depending on the difficulty fishing wires and the types of repairs you need to do after.

@Andrew That is also possible, but a bit different from what I showed and different from what you asked. There are many options, and it really depends what you're willing to go through -- eg are you okay with opening drywall? You can have 3 switches at two locations to control each light AND the fan independently (which means a few new wires and lots of holes in drywall), or depending on the current wiring you may be able to have one switch control both lights, and the other switch control the fan WITHOUT having to open walls up.

comment Digital TV pixelation of picture at Manchester using Winter Hill
The faceplate is loose, or the connection is loose? Have you taken the faceplate off to see if the connection on both sides is good? Tried another cable? Checked any other connections between there and the antenna? Checked the antenna itself for signs of damage? Has anything obvious changed since it last worked? Are there any trees in the way (leaves can block signals; may work in winter but not spring)? With a bit more information on the situation (pictures help a lot) we might be able to help. Complaining about previous people doesn't add anything useful to your question.

comment Do I need to install carbon monoxide detectors to be up to code?
@JMD Updated with a note on applicability. Sorry, I was approaching it thinking of the question as "can I get away without installing a CO detector?" and not "Am I doing everything required to comply with codes?" which I think is what your intention actually was.
