Termyn8or -> RE: Technological advance - duct tape (1/1/2009 8:54:52 AM)
|
I have done some HVAC work, and I have never used duct tape except in repairing this thing, which I did not install.
On a gas furnace with induced draft I always use that metallic tape on the flue for very good reason. If the Bvent or chimney is clogged it needs to build up pressure to set off the sensor that will keep it from igniting. Otherwise it could spew flue into the living space.
The one time I used tape was when I had to build a closed return system before central air was to be installed. The contractor wanted to replace the furnace, which was preposterous. So I drew it up and faxed it to the tinner who made it, in sections of course. Well then it gets there they gave me plenty of drive clips, but no S clips. I used the metallic stuff, but remember this was a return. It was fine.
Boy the things I saw when I was remodeling houses would put hair on your chest, curl it and take it off all in one fell swoop. Downright dangerous. Load bearing walls removed and plaster falling down on people, YES it was done that long ago. They "knew" what they were doing too, right where they removed the support they spead the plaster really thin so that when it cracked it wouldn't open up as much. Real pros. Holes left open in chimneys with nothing but some cheesey cheap paneling over them. I've seen flue pipes that were NEVER connected, of course right next to an old furnace install with open returns. I've seen in a commercial building where someone cheated putting in a grounded outlet, by connecting the ground to the neutral. Little did they know it was wired backwards and made the fridge hot. I've seen cutup extension cords in walls, also wired backwards TO GFI OUTLETS !. This makes a GFI outlet actually more dangerous than a regular outlet.
I have also come to the conclusion that my buddy Jack and I are the only ones in the city that are capable of properly installing a non-prehung door.
And those guys they show on TV selling windows, they make installation look so easy, well the way THEY do it is easy, and totally inadequate. Triple pane low E advanced glass developed by NASA and all that, but drafty all the way around, by some accounts draftier than the originals. When I install windows all the trim comes off and it is sealed. You close that window and you don't even know it's there except seeing it. I put in a sun porch that is literally ALL windows, double hung type, and even without a heating duct out there, in the winter when you walk into in you feel like you are walking inside. It is a tight installation. What these TV schmucks do usually saves you practically nothing unless your original windows were broken.
Why have such a perfect barrier with leaks all around it ?
And plumbing. To borrow a Jewish term Oy vey ! Your drain froze, you mean your trap froze ? Nope, trap's off. "Dude, there ain't supposed to be any water in the drain to freeze". That's why you need traps. I do some plumbing, but not all that much, so I am sure someone else can come up with some better stories. Heating and wiring though, I have some pretty good contenders.
