OP: noted there was no water from the Faucet or Dishwasher, in subsequent follow up, it was noted the dishwasher does work & use of the Hot or Cold produces no water flow. <Q> To directly answer your... | The aerator is mounted on the end of the faucet and is probably not the problem.

Is it safe to use old, rotted wood fixed to an attic joist? I had a pack of old attic boards in my shed. They've been there for 10 years or so. I got them out today to lay them in the attic and found the packaging had broken and some damp had got in. One end was white and flaky enough to crumble with my fingers. It has... | The old chip boards (particle board, oriented strand board and even plywood) from years ago were made with glue that wouldn't stand up to moisture.

How can I power a load from two separate circuit breakers? On one circuit breaker I have a manual switch. On the second circuit breaker I have a motion sensing switch (using a mechanical relay). I have a number of lights wired in parallel as the load. The lights should turn on as a result of motion or manually turning ... | Then either switch can operate the lights and if both switches are on at the same time nothing bad happens. You cannot entangle two supplies like this, it will create a death trap. You don't need to do this.

AC - frozen tubes, no air flowing when fan on and system off Last night I realized my AC stopped working. I turned the thermostat to 74 degrees and by the time I woke up the house temperature was 80 degrees. My home has a single Carrier compressor (obviously outside). The air handler, evaporator coil and blower are ups... | The AC coil in your ductwork is freezing due to insufficient airflow across the coil. You'll probably want to get the coils cleaned, if there is algae at the outlet, there is probably in the unit.

Why is woodwork relatively meager in modern homes? I notice that older houses tend to have much more massive and finely wrought woodwork than new homes. For example, here is a railing from an early 20th century house: Notice the elaborate paneling on the floor siding. We can compare this to a typical railing found in... | Home buyers have deliberately traded richness of design and quality of construction for sheer size.

What is the generic term for kitchen counter laminate without particle board? I'm trying to see if I can buy the laminate that kitchen counters usually have, but without the particle board underside. I'm trying to resurface a desk with something stronger, and it would be easy to simply adhere a strong laminate layer on... | The generic term is simply "plastic laminate" or "high-pressure laminate".

Any thoughts as to what these wires might be? Red/black/orange-ish/yellow. New house. In the front closet, right next to the front door, there's a low voltage junction box with (seemingly) two sets of wires—red, black, orangey, and yellow. I've tested them and there doesn't seem to be any voltage passing through. On ... | Once you have ruled out live active power, and open connections on each wire, use a ringer like a Fluke ringer/toner and trace the direction of the wire through the wall, potentially to its destination. I had a similar issue in a similar place at my house and they turned out to be extra wiring for Christmas/ Holiday de... |
How do I remove this Schlage double-cylinder deadbolt with no visible screws? Does anyone know how to remove this dead bolt that has no screw heads to use a screw driver? Here's a picture below. <Q> Those are just metal "caps" that push into the screw heads.. <S> The screws are located under those metal "pins"The m... | Take a very sharp small screw driver and pry under those caps and they will pop off revealing the screw head.

I've stripped woodchip wallpaper with lead paint on it. I think I have all the dust in my carpet and furnitre. What do I do? I'm 17, I wanted to decorate my bedroom and decided to start stripping the wallpaper as my dad is working on other things at the moment (planning on moving house soon). Our house was built around... | What you could have done was get a mask for lead based paint - microfibers - like painters air particulate masks. Put your sheets outside and vacuum them outside.

Drywall taping/floating steps if finish will be skim coating I am finishing up a master bath remodel which involved removing some walls, and creating new walls. I have: Hung new sheetrock for the new walls Patched the ceiling where the old walls were with drywall (~4.5" wide strips) Patched some gaps with hot mud ... | Then you can decide what dimples need pre-covering and which can simply get covered in the skim coat. If you exceed the max depth you might get hairline cracks, but [in my experience] that only happens on larger areas, not screw-size... and you can fix it anyway by filling the crack(s) with the same compound, which usu... |
changing water pump outlet connection from 1.25-inch to 1-inch, how to calculation flow and pressure Submersible well pump with 1.25-inch outlet connection I've changed to 1-inch how to calculation the flow and the pressure? Here's the submersible well pump details with standard 1.25-inch outlet connection.

Name for a partially-circular metal clasp that fits into an indentation in a tube What's the name of the "circle" that the arrow points to? In the picture is the end of a barbell. That thing that arrow points to is put onto the tube. The tube has a "dent" where that circle fits. There are eyes in the end of the circle... | I've also seen them called C-Rings* or C-Clips, to differentiate them from E-Clips/E-Rings.

What do i need to stop my computer from rebooting in electricity fluctuations AC 240V location. My computer at home keeps restarting at the time of fluctuations and i loose all my work, this happens minimum once every day and some days more than 2 times. I have 1100va Microtek Inverter ( Microtek ups sebz 1100va ... | Getting a more reputable UPS (with data connection/collection that you can connect to say a laptop, so you can troubleshoot it) would probably be the best way to proceed here. My guess is your UPS probably has a subpar or incorrectly calibrated AVR, which probably explains why if effs up on some fluctuations but not on... |
Switching power to an air compressor I have an air compressor for running tools in my garage. I recently moved the compressor to the basement and put an accumulator tank in the garage ceiling. I did this to reduce noise in the garage and outside. It works very well, but now I'd like to control power to the compresso... | To control the compressor pictured, you will have to improvise a mechanical means of rotating its provided power switch in either direction. An A/C relay probably costs $30 or less.

Removing old thermostat when replacing electric baseboard heaters We're renovating a 30 year old home in the US and replacing three 240 volt electric baseboard heaters with new, modern heaters. Currently, each of the three 15+ year old heaters are wired into their own "dumb" analog thermostats on the wall. We're looki... | And, if you do replace the thermostats, then you may not need to run new wire.

Non-destructive test to determine 110V electrical in backyard pipes? I have 3 plastic pipes in my backyard and one (two?) of them have 110V lines in them. All wires - hot, neutral and potentially ground are inside the pipe so I can't just use a clamp meter / current transformer. Image below, you can see two white PVC p... | This is Very Bad normally, because it makes anything inside the loop the core of a transformer - and will cause eddy current heating and very high EMFs. You can use a clamp meter / current transformer if you have any such size, Or you can wrap some wire around the pipe and measure the induced voltage with DMM when you ... |
How to best clean unsealed kitchen grout so that it can be sealed and/or regrouting later I have a problem with unsealed kitchen grout on ceramic tile as it has never been sealed and dirt has allowed to set in. In addition it probably needs regrouted later (pictures below) but sealing it could prevent damage and allow ... | Steam is the best for that; it removes all dirt and stains most of the time, and leaves no residues behind.

Stuck Faucet Handles - How do I remove Can anyone tell me how to remove these faucet handles? I have removed the allen screws and removed the faucet handles. But then I assumed the cones under the handles woudl screw off, but I cannot get them to budge. Is there a trick to this? I do not know the make/model. I hav... | The answer was to put the handles back on and turn them counter clockwise to unscrew the rest of the part that held the ceramic unit that needed to be replaced.

all my 240 circuits aren't working anymore in sub panel but the sub panel is getting 240 volts am having an issue with a sub panel in my kitchen. I am reading 240 volts across the red and black coming from the main panel, in the panel I am reading 120 from each conductor to ground on all circuits. But on all of my doub... | If you have 240 at the main lugs of the sub and do not have 240v at the breakers the main breaker could be bad.

Issue with clocks running fast in my apartment I noticed recently that my bedside clock and oven clock, which are both powered from the wall, were about 15 minutes ahead. I changed them back to the correct time, but the next day they were already a few minutes ahead. I have also had a few WiFi routers suddenly stop wor... | It is conceivable that too high a frequency is upsetting your routers.

Electrical Code for wiring multiple outlets Is there a code that states whether a pigtail is required for each outlet or if the second screw on each outlet can be used to continue current to the next outlet in the series? Since the only connection is that thin metal clip I was wondering if that is considered a proper ... | You can use the screw or pigtail. The NEC simply indicates that any connectors or devices have to be listed for that use.

How to get a TL light working I have a set of fluorescent tubes (2) in my kitchen and they both do not work (noticed while I came home). Normally one of the starters is broken and I replace it but this time both lights to not work. Changing starts neither. What can I best do component inside but I don't know if I ... | If the fixture will not light with new lamps the next item would be the ballast (most of the time it is cheaper to purchase a cheap fixture with a ballast and use the ballast in the old fixture. Once I have settled on the tubes to be used, I would then look for an electronic ballast that is compatible with the tubes. I... |
Can a clear tube added on the outside of a water tank be used to read the water level? I have a water tank that I want to read the level on. I would like whatever device I use to be passive. I have seen the 'cat and mouse'-type weight and pulley device, which doesn't suit my purposes (I would like something self-contai... | I placed a piece of clear tubing from the bottom of one of the tanks and ran it up the side. Those of us that have serviced or installed boilers are familiar with this procedure. Don't bother with a big-box home supply store, go to a plumbing supply shop and talk to the oldest guy there.

What type of cable should I run to future-proof an outlet for an air conditioner? Our new house is still under construction by a standard builder. After the home is finished, I will be installing a small mini split ductless AC system for a home office that will get much warmer than the rest of the house. I received pe... | If you think you would need two circuits for equipment and wouldn't want a subpanel, then you could run two cables out there. Voltage is not an issue since any wire you're allowed to use is good for 300V. Installing a n-3r (raintite) junction box would be fine. However Cables cannot be paralleled so two 10/3's cannot s... |
Are there concerns with leaving part of a home's ground level unfinished? I'm designing a new house for myself, and I've always wanted a basement so I would have unfinished hobby space. The kind of space where you can get messy stuff on the ground like water, paint, sawdust, whatever, and nobody cares because it's just... | But you have to also consider the cost per square foot to build the structure that covers the slab/basement. Generally, it needs to fall into the category of "Uninhabitable Space".

Shared neutral on the same leg I have a two bedroom cape with 14-3 running to the second floor where it splits. I noticed at the panel some time much later that the two 15 amp breakers that power up the individual rooms, are separated by a 20 amp breaker that feeds a designated circuit. The 14-3 neutral is carrying th... | You do want the two breakers for a multiwire branch circuit to be right next to each other so the handles can be tied together, but in terms of overload protection and the effect on the neutral, it should not be a problem. Be careful not to split up another multi-wire branch circuit. Verify that your panel bus is stagg... |
How do I get a dishwasher to fit with pipes in the way? The installer showed up with the new dishwasher ( KitchenAid KDTM404EWH ). Once he took the old one out, he found that these pipes are in the way: Any ideas about what I can do? The installer said I'd need a dishwasher with a depth no greater than 19.25 inches.... | The back left of many dishwashers don't have anything there, so at the worst you would just have to modify the support/frame depending on the specific model of dishwasher you purchase.

How to avoid cutting electrical wires when cutting into drywal I want to install an attic access pull down ladder in the ceiling of my garage to put plywood on the rafters for storage. How do I know where to cut into the drywall of the ceiling without cutting wiring? <Q> First you need to lay out the general area wher... | Preferably with a drywall saw as you aren't going to do much damage to the joist with it. Start your hole from above. You can't count on the ceiling being framed strong enough to serve as storage. Cut to the joist in each direction, enough off center to work it from both sides.

Is using a non-GFCI circuit more risky now than before GFCI entered the electrical code? When using a non-GFCI grounded receptacle with a modern device (e.g. manufactured date 21st century) are the risks the same as they were in pre-GFCI era? I can imagine some situations in which risk is higher, for example if manu... | But as far as device safety I would say things are safer because of lawsuits in the past and the materials used in modern manufacturing.

Concrete vs crushed gravel for fence posts in clay soil? I'm prepping to build a fence in the back yard and am going back and forth between using crushed gravel and concrete. I've read lots of differing opinions on the pros and cons of each. I'm leaning towards using crushed gravel as it's easier to repair posts if th... | Using concrete will help the post to last longer, if you create a dome of concrete above soil level and make sure it is smooth and tight against the post.

Will a magnetic flashlight attached to a metal junction box cause problems? I have a metal light switch box that is mounted on the outside of a wall and I would like to set a magnetic flashlight on it. Is electricity adversely affected by having a magnet near it? <Q> Short answer: <S> No. <S> Long answer: Nnnoooo... | Mostly though, the magnet, could, if strong enough, alter the voltages enough on the circuit lines of delicate electronics enough to cause issue. Won't make a difference

Then there's the receptacle cover plate that is la... | Be sure your tape measure is parallel to the edge of the sheet when measuring. Just trace the outline of the box onto the wallboard and cut. Then the cover plate helps you hide any gaps. With drywall you might be able to go with a rough location and cut the edges while the board is held or lightly screwed into the wall... |
Do I need to replace my copper gas line before installing a new dryer? Why? Just purchased a new dryer, and when it was delivered the installer said he could not connect it to our soft copper gas line -- he said it needs to be replaced with another type before he is allowed to touch it. He also said that any appliance... | Some years ago, the use of flexible copper lines were frowned upon by all the gas line governing bodies. So as @Machavity pointed, out it is probably a liability issue.
