Finally climbed up in the attic to get the water descaler installed. Instructions said it was best to install it where the water main enters the house, which meant I had to get to one of the corners far from the access hatch. Didn't have enough boards to get where I needed to go, so had to shift some stuff around. Ended up taking the large piece of MDF from my failed vacuum table project and a scrap piece of plywood, using those near the hatch, and moving the smaller ones further out in the tighter places.
Forgot to put knee pads on, so halfway through wrapping the first coil, my knees reminded me just how big of a mistake that was. Wasn't about to go get them, and have to make another round trip, so gutted it out and got the 2nd coil wrapped. Nowhere to really hang the module or mount it, so put a 2x4 to prop it up so I can see the indicator lights from the access hatch (if I hold my phone up high enough) Now just have to wait, and see how well this thing works.
Got cleaned up, now relaxing for a bit. Need to go get some groceries for tomorrow, and the next week, fill up the EXT. Probably a few other errands I should take care of too, and not procrastinate.
