Well howdy there internet club dwellers
It's Troy again
Just coffee today Flo...
Speaking of coffee, let's talk about Patrick's cuppa joe, and a couple of holes
Edit: I see that I was correct, but late with my advice. Story of my life.
Patrick - You probably already have, but check to see if there is an inline shutoff to the brewer. When we moved into our new condo, the previous owners had been smart enough to plumb the line to the fridge - not with a saddle tap (hate those) - but with a real line and valve! I turned that on the first day we were here.
What I didn't realize was they had a separated the line for the dishwasher. It too had a shut off valve in the basement, no where near the dishwasher. We ran the dishwasher for a day to "rinse" the otherwise clean dishes we had packed in the move. Since wife wasn't putting soap in, she didn't realize there was no water to the thing.
It's probably not that issue, but I thought I would assume my role, don my cape and spandex outfit at
Captain Obvious...
Now, what about the holes?
Well. This is what I did over the last few days.
There used to be bricks in the wall where that board is. I caulked around it since I took that picture. It only took a hammer drill and two masonry bits to chew threw all of the mortar. Once I broke out a couple of smaller bricks the rest of them shattered and came out easily when I used the mini-sledge and cold chisel.
Yes, I know it's off center and crooked. Most of what I build is that way.

In my defense, I was kneeling in the muck of the wife's flowerbed, sinking past the mulch and into the mud beneath. Not sure if she had one of those plants who told Seymour to feed him... I tried to work fast.
IF we get another decent day, I'll toss another coat of paint on it. Next spring, when the maintenance guys get the trim paint out, I'll get some of the "Official" color and give it a good coat to match the HOA coded color. But, for now it's functional.
Why exactly did I make that hole?
Well, there used to be a vent there. Our electrical panel has one breaker labelled as "Kiln"... so I suppose someone enjoyed casting pots, or baking greenware? But they bricked up the vent when they left, or such. I got permission to open the hole back up to add a vent fan for the hobby room. Since that area also has the gas furnace and gas water heater, I couldn't move the spray booth or the Isopropyl Alcohol rinse station for the 3d Printer back there. I needed to add a vent fan.
Until I can get a fan, and plumb a couple of Ts into it, I'll just use the spray booth as the vent van. For now, though, I do have a pipe run. I need to move my hobby tables and printers back there this weekend.
