> you got to figure slope and elevations
I mean, you should... but there's still a lot of wiggle room on the way from doesn't meet modern code / never met code / shouldn't be done / is unsanitary or unsafe / will not work.
Residential electric is easier to do in ways that work but are either not to code or not to common best practice. The handier the previous owner was, the more new ways to do things you can learn. If a previous owner was in the trades and also heavily involved in the initial build, expect lots of weird repairs. :p
Again electric is not complex.I would say modern residential wiring is pretty fool proof. The majority of the work involves stripping wires and tightening screws. 120v is quite low vs street or transmission line voltage. Yes mis-wiring can kill you or burn down your house but it really takes some effort + stupidity. Nail into a wire, arc fault breaker trips, similiar for other faults. The electric code is far more nanny than plumbing code. Sure if you run a 40 amp dryer off 14 gauge romex with a 40 amp breaker you may have a fire but more likely the wire gets hot maybe melts the insulation and shorts and trips the breaker regardless. everything in wiring is over engineered to prevent fire and death even in the case of improper installation or damage. Meanwhile let's say you plumb a gas line wrong and gas leaks into the house and blows up or boiler explodes from lack of functioning pressure relief valve. Electric has defense in depth as it has layers of fail safes.
Oh... You're talking about plumbing gas lines? Gotta be real careful with the slopes on those, yeah?
