When you’re in “GET ER DONE” mode, you don’t always consider the long term ramifications. OK- I might get over the outlet in the shower. But I will not accept the toilet paper holder IN the shower. When the power company told its crew to run electricity to this house, I'm sure they didn't mean to just stick all the wires through a hole in the roof! Pretty safe isn't it? I mean the hot lead is at least a quarter inch from a metal oil pipe and it is almost 48 inches off the ground so children won't touch it... Yes- go ahead and connect the dryer vent to the water heater flue. What the hell? The county inspector had JUST signed off on it. Said it was "all he could do since it was a remodel". If you can't bend metal conduit, just use a few extra junction boxes! You know you're a redneck HVAC tech when you use a chew can for a junction box. When you do not have an outlet box, use a Nike box.Just do it! "Screw that I-beam- just cut it. That is the framer's problem." Instead of flashing the penetrations, install buckets with pipes under the drips. .........shower and ceiling fan in master bath...." Hmm.where does the wire go and how much glue did he use to stick that thing there? The ad listed the house with a "whole house attic fan". Professionally installed no doubt. If you can vent ONE bathroom exhaust then you certainly vent THREE! "I paid an electrician to do it" "Flashing!? We don't need no stinking flashing!"
