comment Calculate savings from/cost-effectiveness of installing a tankless hot water heater?
Do you have any justification for the assertion that moving from electric tank to electric tankless is a "waste of money"? (I'm not saying it's necessarily wrong, but I am not convinced it is always true).

comment can I buy a saw made of nylon?
If you explain what you're trying to do, someone may be able to offer another solution as well. Pictures are very useful.

comment How can I fix a loose door frame?
When you say "loose", do you mean it moves when the door shuts, or you can actually wiggle the frame with your hands while the door is open? How much does it move (1/8", 1", ..)?

comment How can I test network and coax jacks?
Not sure how long your multimeter leads are, but mine are definitely not long enough to reach from an upstairs bedroom to a basement patch panel... You can still test those with a multi-meter though, using a coax (75ohm) terminator. Screw the terminator onto one end, and at the other end use your multimeter: you should see 75ohms (plus some loss for cable length) center to shield.

comment Is there a filter-reminder thermostat that uses run-time instead of total time?
I think the reason they don't do this is exactly what Tester101 is saying: When it's dirty, it needs to be changed. Without being able to directly measure if it's dirty, all you can do is estimate. Air quality is by far the biggest factor, and the amount of runtime is entirely based on the air quality (eg, if the air was 100% clean, the filter would theoretically never need to be changed). While measuring runtime is going to make things more precise, it will not be more accurate, so there is no point in spending effort on this function.

I'd also guess that drywall screws placed 12" apart will look continuous to most metal detectors.

comment Is it possible to retrofit an external kitchen fan in an existing house?
Would you consider just replacing the fan hood with one that is less noise? Noise is measured in Sones and vent fans all have that as a rating. Generally the cheaper the fan, the noisier it is, and builders will put in the cheapest fans unless you specifically pay for the upgrades.

comment What should I do about a receptacle with 2 circuits going through it where white wires are hot?
This is an example of why you always should have a non-contact voltage detector, and use it basically every time before you touch any wires, even when you "know" they are off.

comment How can I convert wall lights to under-shelf lighting?
@ChrisF Can you clarify your "plaster over the hole" statement, as it sounds like you're suggesting to cover up a junction box. It is against code and dangerous to have hidden junctions. Any connections must be accessible and contained in a proper box.

comment How should I pump water throughout a house from holding tanks in the basement?
Technically yes. Each pump is rated for certain flow rates depending on the amount of total head (total head = static head + friction from length of pipe; static head = the vertical distance from the top of the water level to point of use), and you can get this info via the performance curves for that pump (should be provided by mfg). That said, in your case, the total head is going to be so small that almost any small pump will work. Do be careful of over-sizing though, if you throw in a big deep-well pump that can do 20 GPM, it's going to turn on and off so quickly it'll be hard on the pump.

comment Can I increase air volume by adding more fans?
Fans in series vs parallel, for reference: ebmpapst-ad.com/media/content/technical_articles/…

comment How should I pump water throughout a house from holding tanks in the basement?
Are you set on using the tanks -- why not have the supply directly from the well? Water in tanks has a much greater potential of being contaminated. Typically cisterns or tanks are only used in residential applications when the well cannot produce enough water to meet demand so it runs dry during normal use -- kind of like using a battery with a solar panel, so you can still have power during the night, or still run a dryer and stove at the same time even if it's really cloudy out. Of course, this is probably more expensive, but it does increase the potential resale value.

comment How should I pump water throughout a house from holding tanks in the basement?
A jet pump is going to have the issue where you either need to have a hole in the bottom of the tank for it to draw from (this increases the risk of the tanks leaking), or you will have to prime the pump to get it going. A submersible pump in the tank will be much more reliable and much quieter, but is more expensive. Do you have a budget in mind? What kind of flow rates do you need (not much, by the sounds of it)? Is there any treatment system installed?

comment How do I determine which phone line goes where, without any special tools?
This answer could be a bit better if you explain a bit more, and instead of saying "circuit tester", explain how you're using a multimeter to check resistance.
