Speaking of hot water heaters, where I live, homeowners are NOT ALLOWED to install their own water heaters. They must pay a “certified professional” a “fee” to have it installed for them.
TYRANNY, so much TYRANNY.
I’ve got to admit something. My family’s wholesale plumbing supply store sold hot water heaters so I knew what parts I needed and learned from my father and our plumber friends how to do it.
I used a mirror (the heater was way back in a corner), a blowtorch, and some good solder. Took me about 15 minutes because I had to hold the mirror in one hand, heat the solder and then drag it around the fittings threads to make a solid bead.
I might even have had a small flashlight in my mouth.
As Blutarsky would say, “Nine years of college didn’t go to waste”.
Because Water heaters have to be installed as per building code. People are stupid. Families would be electrocuted or smothered depending upon whether it was electric or gas heater.
