Can I cut out a leak, in the middle of a stainless braided water line, and splice it back, under the kitchen sink?

Unless you have a considerable array of specialized hose-crimping equipment - No, they are disposable, not repairable.

Your run is too long for your GFCI Your GFCI is tripping, not necessarily because your pump is faulty or your GFCI is broken, but because you are well outside the 250' maximum cable length limit in ...

Are split bolts wrapped in splicing tape rated for live connections?

If you are discontent with the quality of wire nuts, you can go to a proper splice block. These are my go-to for anything larger than 6 AWG. Source The wires are inserted in the side, then they ...

Can I cut out a leak, in the middle of a stainless braided water line, and splice it back, under the kitchen sink?

You probably could do that and have it last for a few minutes. By the time you found the proper size rubber connector and hose clamps, you'd have spent more than buying a new supply line. And that ...

To answer your question, split-bolts properly insulated (as you've done) certainly ARE rated for "live" conductors. Ask your inspector to provide the code citation prohibiting them. For decades split-...

Live wire spliced in a switch to provide power to other parts of the room!

Your analysis of the current situation is correct and quite normal. The fact that this type of switch allows two wires to be attached under the switch makes it that much easier to do, as opposed to ...

What's the proper way to extend wiring into a replacement panelboard?

This is a tiny 8-space box. Simple solution. Don't replace it with another 8-space (or even 12-space) box. Put in a much bigger panel. 20-space or 24-space would be quite reasonable. It can even have ...
