There are MANY things that determine quality of water, common ones being: "Nuisance" Bacteria Not always harmful, but they do release iron and sulfur into the water during their life cycles, and form a biofilm on the well surfaces Disease-causing bacteria Most common are e. coli and coliform, but can also include fecal coliform and fecal streptococci ...

Very good question but you need to find out more information. The very first question on my mind is.. Where do they connect to ? if they are connected to anything else at all? A simple solution Find the starting point(A) and the end point(B) of either cable. Using a multimeter and a return cable* you test continuity of the cable. Either using Ohms = 0 ...

The gauge refers to the thickness of the steel, which is but one measurement of the quality of the stainless steel (the other main factor is the grade of stainless steel it's using) see: Steel Grades on Wikipedia. As for measuring the gauge , you can get a Sheet Metal Gauge online, or from your local hardware store.

“Water quality” is not one-dimensional … what kind of contaminats do you want to test for? If the answer is “everything” or “I don't know” then start by finding a reputable local lab, describe your concerns to them, and see what they recommend based on their knowledge of the water in the area. Once you have done a thorough one-time test, you will have a ...

A Hygrometer is used to test the level of Humidity. I'll bet that your levels are very high. High humidity can lead to health issues with mold groth, not to mention it can destroy your home. Things you can do: Vent the dryer to outdoors, a big source of the problem! Add a bathroom vent to the outdoors, not in an attic or other room! Run the fan for 30 ...

A non-contact tester might give you a false-positive on the neutral in some cases. Try testing the outlet with an outlet tester which will indicate if the hot/neutral are switched or open. Alternatively you can use a multi-meter to test it. If you are in the US, you should get ~120VAC between hot and neutral, but 0VAC between neutral and ground if the ...

You can use your cable modem itself as the tool. Do a search for "[your modem manufacturer] cable modem diagnostics" and you'll find out how to access the modem's diagnostic page in a web browser. This will give you upstream & downstream signal levels and lots of other useful info. Here's a page with some information about a few different ...

You can use the tester below. If you touch one probe to the hot and the other to neutral or ground and the bulb should light. If hot-to-ground lights but not hot-to-neutral the neutral is open. Vice versa for open ground. If you get nothing lighting either both neutral and ground are open or there's no power. If hot-to-neutral and neutral-to-ground light, ...

The easiest way to test the output of a transformer is with a multimeter which can measure both volts and ohms. If the transformer is wired into the 120VAC, and the power is on, remove any wires on the 5V side and place the multimeter probes/clips on the two connection screws on that side. You need to read the transformer output rating to see if this is AC ...

Given the 110V tester, I'll assume you are North American locale for this: Look up your outlet type. Test (using appropriate care) that you have 240V from the L1 to L2 (hots) (you presumably did this per your question, but make sure it's the correct terminals) Test that you have 120V from each hot to neutral. Test that you have 120V from each hot to ...

Continuity is "An unbroken electrical path in an electronic circuit or connector[1]". First thing, unplug the dishwasher or if hard-wired turn off the circuit breaker. Unplug the connector to the heating element and then test the contacts on the heating element. A heating element is a semi-conductive (typically coil) that creates heat as it resists the ...

I wouldn't bother with making smoke—at least not initially. If this is in an apartment or condo, that might set off a smoke alarm. The surefire solution is to poke your head up into the attic with a bright hand held light. If you can't see the bathroom fan area from the access opening, you'll have to crawl through the attic until you are close ...

Amazon carries home mold tests. I have no idea if these are any good, but they are pretty inexpensive:

Yes! For goodness sake, do NOT put any commonly available potential (ie 120V) on the lines, they make very easy to use tools for this. Most sources in your house will be voltage sources, vice current sources, so how much current results is a factor of the resistance in the line. Because these speaker wires will have low resistance when you find both ends, ...

In a switched outlet, the following is correct: Switch on = normal (2 yellow lights) Switch off = "open hot" (no lights at all) The yellow light that comes on for "open ground" indicates whether an appliance will have power in that outlet. As you might guess, it is connected between hot and neutral. The other yellow light is connected between hot ...

My thoughts on your first question would be to take a sample from a few different rooms, if you can see any differences between color/texture on the ceilings. From asbestos.com: If the material looks different (especially in color or texture) in different parts of the room, plan to sample each of those areas. For a ceiling surface in a large ...

I'm afraid any stand alone meters are going to be pricey. There are two types to measure RF signal level. One that you set on a frequency and read the power level at that frequency. The other is called a spectrum analyzer and shows a waveform of the power level across a range of requencies. That is what is really needed to see whats going on. I'd try to get ...

This makezine article links to this DIY-electronic project (which probably not what you want to spend a week building) but there's also a link to readymade alternatives like Mavromatic HM COM-100.

I'm not a fan of the test kits. I recently had some mold issues and used a mail-in tape sample to test for mold. I did 8 samples for $50. I think 3 or 4 samples can also be done for lesser price. Here is the site I used: http://www.mold-control-on-a-budget.com/ (I'm not associated in any way to her but can vouch for her service and professionalism after ...

First of all, you need some SCIENCE! A multimeter measures one of three things: Current, Voltage, Resistance. Current (I) is the flow of electricity (how much water goes over the falls) In a one path circuit, the current is a constant throughout (i.e. ALL the water reaches the bottom) Voltage (V) shows how much potential energy the current is carrying. (...

I would recommend looking at the tutorial from SparkFun: How To Use a Multimeter. It is a bit specific to the multimeter that they sell.

If it is a shingle roof, a pressure washer is going to tear it up. Barrel tile is another victum of presure washers unless it is a whole new roof. Old tiles will disintergrate because the bonding agents used to make them grow less adhesive as time goes by. You should only use you garden hose and let the water run from at least three courses above the old ...

A hand held anemometer can be used to see the flow then multiply by area to get the total flow. There are quite a few for under 20$ .

Your test procedure is a good start. However, you should confirm 0 volts between all possible combination of wires, including ground. And if your water lines are copper, test between that and the wires, too. Also, you are wrong about the function of the wires. Black is hot, white is neutral, and bare is ground. You got white and black backwards.

The tester should read open hot when the switch is off, as switches always go in the hot wire -- it most certainly shouldn't read open ground with the switch off! This means that Outlet 1 is quite dodgy in some fashion or another, while Outlet 2 likely either lacks a ground or doesn't have it hooked up.

You can get a smoke bomb. A firework. Just be careful not to burn down house. Use a large metal container.

If they are not terminated, they have no signals at all, until you terminate them and connect them to something. Blue/white(with blue stripe) is normally the "line 1" pair in cat 5 cable used for phones. Green/white(with green stripe) is the standard line 2 pair, in the presently unusual case that you actually have 2 land-lines. Pins 4&5 for blue, 3&...

It seems that this document answers most of your questions: Testing for Lead In the document it states that home kits are available, but it has been shown that the effectiveness is not too reliable, and if you do detect lead, you will probably need to get soil professionally analysed. otherwise you can find do-it yourself test kits on this link if ...

You need to identify each pair of hot wires with there corisponding neutral first try starting at the romex sheath in the panel with the power to the panel OFF and follow each to there termination and label them. And relocate breakers as necessary. If this is not possible it is much more difficult .If you can find the first box that each MWBS is run to you ...
