comment Can a tiny leak get worse?
If there's mineral in the water, minute thread leaks often are self-healing.

comment What type of water pump is also a valve (e.g. will resist head pressure when off)?
For solar use, there are available, positive displacement diaphragm pumps. They have inlet and outlet check valves on the diaphragm chambers. Other positive displacement pumps like rotary lobe pumps will attempt to turn into hydraulic motors if they don't have a check-valve in the outflow.

comment What could green covering on a radiator pipe be?
Yep, Algae is slimy, you'd have stringy stuff, corrosion is crusty and flaky and bumping the dry portions will leave flakes and powder on the floor. It's the copper form of iron rust. What you see is accumulating from water evaporation of a solution on the outside of the metal pipe.

comment How can I make a bluish “white” LED less blue?
The way to change the color of an LED lamp is to change out the LED. Filtering for narrow spectrum light sources merely filters out the light. Also, the bluer LEDs often have UV output that causes issues. You need to start with a proper light source which would be probably 4300K or warmer White LED with a phosphor mix that gives a good CRI (broader spectrum white light). White LEDs work by converting ultraviolet (like common fluorescent lighting) to white light with phospor powder embedded in the plastic lens housing.

comment Single connection 2+ cable devices with splitter
The proper term for the "splitter" used when you have cable modem Internet service is a tap. The cable modem goes on the 0db loss output port (trunk) and the tv services go on the 3.5db loss port. They are also known as a directional coupler and provide a lot higher isolation between the trunk and service ports so your tv/dvr, etc don't feed back interference into the cable modem. A splitter/combiner can feed back interference from either output port into the other port, so not only do you have insertion loss on the modem, but you also have potential hash leakage back from the TV.

comment Is the Electrician trying to scam me?
No, I don't think you do, but the issue exists, doesn't it that a properly wired panel out there in an older installation with these named panels could pass wire heating amounts of current without tripping, correct?

Read up on Federal Pacific and Sylvania/Zinsco breakers. You can't determine if they are faulty till you measure the results and find they are not tripping. The Federal Pacific units fail such that they cannot be shut off.

comment Is the Electrician trying to scam me?
there is NO way the circuits could be pulling more than 35 amps Never make a blanket statement like that <grin>. How old is the house? Was it built in those years where certain notorious Circuit Breaker panels were manufactured? Certain things must be determined before blowing off the electrician as a cowboy operator. Get a second opinion by a reputable electrician's firm.

What circuit breaker panel is being used for circuit protection? Sylvania/Zinsco and Federal Pacific are notorious for not tripping and allowing excessive current draw. Seeing melted stuff is not normal operations unless you want flammability in your future.

comment What are the consequences of building without a permit?
Several Follies in the surrounding neighborhoods. Partially built unroofed garages, unfinished patio overhangs that got cease and desist orders after the owners had paid thousands putting in foundations, framing, exposing structure for tie-in. Locally, you seemingly aren't required to tear it down, but you can't get a permit to finish and probably need a permit to tear it down. It also cannot be covered by insurance so property contained isn't insured.

comment How can I store Latex paint for the long term - a decade or longer?
Repackage into well sealed smaller plastic paint buckets (properly labelled for contents) to minimize air volume. Three killers of paint, oxygen available for polymerization/oxidation, evaporation of solvent (water/mineral) and rust (if they're in tinned iron buckets).

comment Can fiberglass insulation cause leaks?
Today there's a fierce thunderstorm, Umm, there you go, uncommonly intense downpour, water pooling against flaky flashing and of course it's going to leak. Insulation isn't going to cause this to happen, it's just going to happen every time you have this much water hitting your roof. And lots of water going into the ground causes a fracture in the basement wall to stream water. I know a guy whose basement used to flood every time there's an intense thunderstorm, he wrote articles about basement water pressure and the need to have drainage. Again, not the insulation, but the rainstorm.
