I haven't started brewing yet, still getting my kit together veeery slooowly. Threads like this great to help someone like me avoid buyers remorse. I got a couple kettles and some random equipment and didn't really know where I wanted to go from there. I found this site I'm setting up a system like this one. Probably should have ran that decision by you guys first but most parts are already en route, well the hardware not the electronics yet. Will be 10gal HLT, 10gal MLT, 16gal BK.
If you do this I'd recommend using Pex if you can. Bought a new house and saw this stuff installed and cursed the builder for being so cheap... until I did a small job using it. I will never go back to copper. Cheaper, easier, faster, no downsides I can see. Also you can get hose bibs that are ~12" long so the actual valve is inside the house. You won't need a separate shutoff valve inside.i tried to do this when i built my house. builder said no. might do it and add a cut off in the basement and drain the line....
