I disagree. You probably shouldn’t rewire your house yourself but changing out an outlet/switch or installing a water softener are extremely easy tasks that would not be worth hiring a contractor for. There’s quite a lot you can safely do on your own as long as you educate yourself and triple check everything.

I mean modern ICE cars can have this same problem.

What brand is it? I currently have a gravity fed 2 gallon bowl but fully self filling would be great.

I use Dvorak too! Have it configured on a custom mechanical keyboard so I don’t have to change anything in the OS either.
