So in case anybody is looking for an update, I'm going to start with the good news. Then I'm going to go to what is probably one of the saddest stories ever (and slightly comical) when it comes to my tradeskills. And bear in mind, I work in the trades for a living, so this is a bit tough to write as it's flat out just embarrassing how wrong this all went.
I installed an outlet where the stand is going to sit, I also put in one of these guys:
https://www.amazon.com/gp/product/B07H9CSY8T
But I only used one of the pair that it comes with. From this I ran 3 RODI 1/4" lines up. One will bring fresh RODI for the ATO, one will bring fresh saltwater from the mixing drum, and one will take old tank water to the drain, the last 2 will run via the DOS and the first one is just a simple float valve.
That's the good news. Now for the odd, absurd, and bad news:
First, the mildly humorous bit: I ordered a float with an acrylic 'clamp on' style holder via an
Amazon reseller. When it arrived, the padded envelope was completely empty. Not even paperwork inside. And it was still fully sealed, meaning they literally shipped air. Had to go through the whole procedure of refund via chat since there was no object to send back, and then I decided to switch vendors and ordered an Eshopps float with bracket.
Now for the tale of woe: I drilled the hole for the power through the bottom of the wall, using the outlet opening, with one of those long flexible fishing bits electricians used. Ran the wiring, put the box and GFCI in, and bingo, all done with that. Worked super easy. I moved the bit over 4" into the hole for the RODI tubes, and it got completely stuck. My 12v drill wouldn't drill in, and took quite a bit of struggling to get it to reverse. Moved the hole over about an inch. Same problem. Moved it one more time... got it so stuck that I broke out my 18v drill. It was torquing it in reverse but it didn't go anywhere, tried going back and forth from forward/reverse, no change. Finally I hear *BOOM*... it caused the drill chuck to internally explode. The jaws are now full open and will not move. My guess is it stripped the internal gearing. I then bring out my corded hammer drill. I pull the trigger and before it can really even start to spin it begins to twirl freely... I pull back on the rod and.... there's no drill bit. It broke the solder that connects the bit to the shaft. It is now embedded somewhere in my wall. Before anyone suggests it, the bit didn't hit anything underneath as the cavity is wide open. I can see the successful hole and the nearest obstructions are 3" behind, 9" right, and 6" foward so plenty of open room. It's possible it hit a nail from the moulding or a drywall screw, but it seems unlikely it would hit those in 3 separate holes.
So then I went to Home Depot, I bought 2 more fishing bits, a spade bit, and some extenders. Mind you, I own almost all of this stuff already BUT I CAN'T FRIGGIN FIND IT! (Garage renovations underway so everything is boxed in 900 boxes and jammed into my 2nd garage). So I start drilling with the new fishing bit using the 'handle' it comes with to steer it. First hole feels like it goes through, run it back and forth a few times to be sure... something doesn't feel right. Go outside and find out the bit slipped out of the handle and drilled through the exterior wall of the house and is now sticking out of my siding. I feel like Clark Griswold at this point. Now I'm getting upset. I go back inside, pull it out, put it back in the handle, get it started, fish my fingers in as far as I can to ensure it's going straight down, and commence drilling again. It gets stuck. Just like the last bit. Except this one won't break off. I put my hammer drill on it thinking the vibration will help it, nothing. It actually breaks the last 2" off the end of the shaft. I reclamp on, try again, nothing.
At this point I finally give in. I cut the wall open down to the moulding. The bit is quite a ways into the wood, so I can't see the top of it. I pull out my holesaw and commence drilling right next to it, hoping that if I can shear the edge of the hole I can relieve the pressure and get the bit back out. No such luck. I say screw it, I'm going to abandon this bit in the wall too, so I drill a bit further over... and discover my hole saw isn't deep enough to go through the bottom plate and the subfloor. Now I'm cussing like an old salt sailor and the wife is laughing hysterically. I pull out my spade bit and a flexible attachment with my angle drill to try and fit into the space without cutting more of the wall open. I get it *right* tight to the drywall. I start drilling and after some cussing and back and forth get it to go through into the basement. SUCCESS!
But wait, I still have a 48" steel rod sticking out of the wall... "How are you getting that out?" she said. "Well, it's now part of the fishtank and will be there until we die. I hope you don't mind the sight of a steel rod sticking out along side the tank." No laughter, just an icy glare. So I run back to the packed garage and start looking for one of the three bolt cutters I own. In true Griswold fashion, I find 0 of 3. So I take my sawzall with my metal bit on it and try to cut the shaft. No luck, Charlie, that's a hardened shaft. It just tears the teeth right off the bit. I reach for my last resort. My Dremel with a cut-off wheel on the end. I slip it into the hole, sparks flying, and *ZING* the bit flies out into the insulation. Luckily I find it, crank down the collet super tight and go at it again. Sparks flying, the smell of burnt dignity filling the air, but at last the shaft comes off.
Wanting to put this behind me as far as I can, I run to the basement, snake the RODI tubes up through the hole, run outside for the last few minutes of daylight to pump a ton of silicone into the hole from my earlier 'exterior' mishap, fill the interior void with expanding foam (since I have now shoved the insulation every-which-way leaving a massive void). I then look for some small wood strips to fix the bigger hole by the moulding. Unable to find any I have an ingenious idea. I take a Home Depot paint mixing stick, shove it into the cavity across the opening, screw it in with some drywall screws, replace the missing piece, screw it in, and mud the gap shut. I'm hoping the foam will expand enough to put backpressure on the piece to give it a little extra support but since it will be behind the stand I think it'll be just fine. As no one will see the patch unless the stand is broken down, I told the wife I plan on writing 'Abandon All Hope, Ye Who Enter Here' on it as a memorial to the two brave drill bits who sacrificed their lives to live inside my wall, and woe unto the next person who tries to drill that bottom plate, because even though it now looks like swiss cheese, I can't imagine they'll win.
