Been on the Internet since before there was an Internet. Remember UUCP, news feeds, and Gopher?

comment Should be concerned with water in water table?
"Water Table" = average level at which water is found below the soil surface.

comment Why would a 5-amp refrigerator need a 20 amp circuit?
With motors, startup load inrush current is always much more than run current. It has to do with motor back-emf, a non-turning motor has only the winding resistance and inductance limiting the current, as it spins up to running speed the stator induces a reverse voltage in the windings that lowers the current.

comment Copper Green Wood Preservative used Indoor? Health concerns? How to Mitigate?
Copper napthenate, think mothballs... The long term stink is from it slowly evaporating and leaving the copper behind.

comment Why do electricians prefer not to use the push-in connections on receptacles?
Because it's common practice in the US to use multiple 15A sockets on a 20A breaker with 12GA wiring.

comment Small leak in 1 inch buried PVC water line
Not necessarily on black Polyethylene when you go to purchase it. Irrigation grade isn't NSF. You have to check. I ran into that last summer while doing a project.

comment Small leak in 1 inch buried PVC water line
Sodium Silicate (water glass) will seal radiators, but I doubt it works very well on soil buried pipes. Plus most things that would do the job won't be good for the plants and animals.

comment Small leak in 1 inch buried PVC water line
And if this is used for drinking water (humans, animals), the Poly Ethylene pipe needs to be NSF rated. PVC also will develop splits when water freezes inside it, make the ditch deep enough to be below the freeze depth so you don't overly test the flexibility of PE vs the rigidity of PVC.

comment Why is Green Glue used so much in the USA, but hardly used at all in the UK?
Sometimes when a question is asked, it helps to know what is being talked about. I'm assuming you are referring to Green Glue Noiseproofing Compound which is basically dumdum in a tube, an elastomeric goo that can be used between layers of sheetrock to provide sound deadening?

Done! Hope that gets the point across better.

comment Re-use circuit breaker handle tie?
As long as the circuit details (one pulls off L1 and the other pulls off L2) are taken care of and the tie bar stays securely in place when installed AND disengages the other breaker on trip, you should be home free.

comment We hear a constant bass subwoofer like thumping noise every night from about midnight to 7 am
Also available is wave guide tunneling caused by air layer density. The train yard is 3 miles away and across a river, but on certain nights with the right temperature, you would swear the locomotive was running in the next street and when they bump to couple, it can sound like a minor car accident occurred. The rest of the year it's a minor whisper in the breeze. A molding plant up the hillside and 6 miles away in the same direction gave us a low continuous loud hum in our back yard when it bounced off the top of that same air layer.

comment Is it normal for uPVC window shutters to be pre-fitted to the frame at the factory or not?
Does this area have building codes and standardized building practices and was this house built using standardized building practices? Sounds like a retrofit into non-standard construction where proper rough-in opening dimensions weren't available and those always involve a lot of extra makework, tinkering and adjustment. A manufactured window expects a rough-in opening of a specific size and generally drops into place with minor adjustment to make sure it's squared up and then fastened into the opening.

comment Toaster oven makes my kitchen lights flicker
Not common enough for me to have noticed it in any house I've ever lived in. Possibly a regional thing? US location.

comment How can I edge concrete without an edge trowel?
Any automotive body shops around? Using a dolly and body hammer on a piece of flat steel or thicker aluminum sheet to form a rounded bend along one edge of a rectangle was a really common skill in the old days of creating replacement parts from scratch.

comment Can we capture the hot, humid air from a gas-powered clothes dryer during winter?
Plus any heat exchanger will clog up with lint over time, creating a fire and backdraft hazard.

comment Is it a problem that the entire element in my electric oven is not red?
Pictures? It's normal for the last 2-3 inches on both ends near the connector block to be black.

comment Can I plug a generator into a dryer outlet
Powering up the transformer that feeds your house is a really bad idea. An interlock system that disconnects the power feed (NOT MANUALLY FLIPPING THE 200A breaker) and connects the genset to the house system is mandatory.

comment Is a PVC union air tight?
This is a safety issue, if this was a working shop, OSHA would shut you down because of the safety hazard. It rates up there, not quite as high as "don't run acetylene through copper".

comment Why do CFLs stop buzzing when an incandescent light is added to the mix?
@mbeckish is correct on making sure these are dimmables. If they are all dimmable, then you've found one of the issues with leading edge cut R and RL dimmers. The rise time is so sharp that it causes issues in the electronics, usually the dimmer is what buzzes. Adding some resistance to the circuit will slow the voltage rise. Trailing edge cut dimmers aren't prone to this noise because the front edge of the sine wave is preserved so there's a normal voltage rise. Change out the dimmer control to one the manufacturer specifies for CFL lamps to totally cure the problem.

comment How can I level a sagging concrete floor in a condo building?
Demolition. 1 ft drop indicates this was badly built with major failure in the geoengineering department while the foundation was being built. Even if the footings have been "fixed" whatever that means, concrete construction doesn't handle structural failure like that well and the building integrity has been compromised. If you live in earthquake country, run in the opposite direction fast, keeping all your money with you, the "view" isn't worth it as the building will probably pancake. View some quake footage for what pancake means.
