Hi Chef. First off, I have not dealt with you directly before, but I have read lots of your posts and have a general respect for your knowledge and opinions. Not looking to cross swords with anyone, and of course you're entitled to your opinion.
I am, however, completely comfortable with what I have done, and can honestly say that my house is much improved from where it started. We have no plans to sell, but if we do, I'll be fine. I can always track down the distal end of those wires and disconnect them, but that might require cutting a few holes in my wall. Didn't wanna do that at this time, and I'm comfortable. There's more insulation on the ends of those wires than there is along the length of them, and it's not going anywhere.
There are so many things that should have been taken care of by OUR previous owner, that we have since corrected (or have identified and will soon correct). Our ---smurfy--- home inspector missed several things; some small, some fairly big dollar issues. Our previous owner was a 40ish mother of two little girls who had recently lost her husband to cancer... we probably could have pursued some compensation for some "undisclosed issues" but out of the goodness of our hearts we just let things go, even though we're out thousands on a couple of the bigger problems. Yes, if we ever sell I'm sure our buyer won't be as understanding, but again, I'm comfortable. I've got one plumbing modification that I know is probably not up to code, but knowing that I designed it so it can easily be cut out, capped and brought up to code when/if it becomes necessary. And I'm fully prepared to do it myself. In my opinion this modification is crucial... the water/sewer dept in our area should never have allowed our home to be built at the elevation it is because we're too low with respect to the pump station across from us so we are at risk of "backflow" whenever there are heavy rains... My mod is almost assuredly not "code" but I had to take proactive steps to protect my family and my home because I simply will not allow my little girl to have a risk of being exposed to other people's waste water just because the sewer district and the builder cocked things up. Like most engineers, I over-engineer pretty much everything. Throw in a rebuilt roof to eliminate some chronic leaking issues, a new deck 4 times as big as the old one (put in by pros, not by me), and hardwood floors on the whole first level replacing some crummy old tile, and I guarantee my home is in far better condition than when we started.
Because of said plumbing issues I even built a home monitor/water detector system that monitors for leakage in 8 different places in the basement and will send me a text and emails to multiple accounts whenever an issue is detected... And acts as a server so I can check the status on a web page from anywhere in the world whenever I need to. It connects directly to the internet, no PC needed. As long as my cable modem and router are on, I'm good. The whole thing is on a battery backup, and I hacked one input line to the signal for the "on battery" buzzer on the UPS so I get an alert whenever the system is running on backup. We have an emergency shutoff valve on the main sewer line in case of flooding issues and I put tilt switches on that, so I can cut power to the basement sewage ejector pump whenever the valve is closed to keep from pumping poop water into a closed sewer system (otherwise it's coming out the drains... not good). Got an RGB LED indicator by the garage door to tell me when water is detected, or the valve is closed, or both, or everything is A-OK. Got a buzzer in the cold air return right by the master bedroom to wake me up at night in case we get a leak while we're asleep. Got a temp and humidity sensor on there too... mostly just for fun but since it's located right next to the hot water heaters it should see a temp and humidity spike if one of the pressure-temp valves decides to dump. It's tight. And I sleep much better knowing that I've got that in place.
I'm not gonna go jacking things up for myself or anyone else. I'm not putting pennies in the fuse box, figuratively or literally. I'm not replacing the ground fault interrupt outlets in the bathrooms with regular ones. Believe me, I am actually PARANOID about things going wrong. In this one thing, I am comfortable. I know how to contain 120V sir. Just the wire nuts themselves would really have sufficed but out of paranoia they have been mummified within about a third of a roll of electrical tape... No harm is being done.
