We have gotten too...something -- not sure what the right word it -

...lazy?

...reliant on automatic systems to keep us safe?

...complacent?


We don't check our car tire pressures any more so now we have federally mandated automatic pressure checking systems. Last time I had a flat fixed, they charged me double because the tire in question had one of those radio transmitters to tell the computer what my tire's PSI was.

I for one (and I know I'm pretty rare in this) check my TPR valves about once a month, and I bang on both ends of my thermal expansion tank about once a month to make sure it's not waterlogged. I check the pressure about once a year.

Now some smart plumber/entrepreneur needs to apply the car tire pressure monitoring system to checking expansion tank pressure! Make a million bucks.
