Well said uppo, basically I was just curious about the codes, I never had any intentions of touching anything, I "know my place" so to speak as just a tenant- But my nature is to learn and I want to know why something doesn't work.
Stairs are ok but 2 years takes a toll on the knees, with a dog that's many extra trips. The kone tech did fix it-- so it is fine for now. Hoping is lasts! Really wish I catch him sometime again to learn more.
