This is exactly what got me thinking about all of this thin oil nonsense. My Toyota Camry has the same, "recommendations". Except it shows all the way up to 15W-40 is OK to use in the foreign country manuals. Where CAFE doesn't exist. They also claim right in the US manual, "A thicker viscosity...

Bradford White is, (was), a good brand. I gauge the level of quality I purchase, by how difficult the install is. If I had a water heater that was in a difficult spot, say inside the house, and a problem to drain, remove, and install, I would go for the best quality obtainable. I did this when...

Good question. Answer, I have no idea. You would have to buy one, chop it up, and start measuring thicknesses, coatings, and such. And I doubt that information is even obtainable from the manufacturer. I base my choosing on, for the most part, these companies are going to set their warranties...

It's the only way I can justify the work and aggravation of doing it myself. (My wife did help. She was, "Hey, go get").

For what it's worth, in the last 40 years or so, I have replaced a total of 4 water heaters in 4 different homes, in 2 different states. 2 were gas fired, and 2 were electric. 2, (including this one I just replaced), were fed off a water softener, and 2 were not. From what I have experienced...

I've never been a fan of "servicing" water heaters by flushing or replacing anode rods. For one thing they're a royal pain to remove. You can tweak your plumbing and generate leaks by using a breaker bar. And an impact gun vibrates everything to the point that alone can cause leaks. Most of...

They would have to be pretty desperate to take that thing. But stranger things have happened.

I took it off and practically nothing came out. It was one of those cheap plastic ones. The new one has a brass drain valve. Once I got it to the curb, and tipped it over a lot of rusty water came out. That stuff was nasty and looked like redwood stain. I'm glad I didn't get it all over the...

Yeah, today they're made from thinner, cheaper materials. And the brand names have sold out to overseas corporations. A lot like all that "Bell & Howell" crap they sell on TV. I basically go by the guarantee. The longer the better. If this one lasts 9 years I 'll be happy..... Hell, if I last...

Last week I noticed my 4-1/2 year old A.O. Smith water heater started leaking. (There was dried rusty water stains in the bottom of the pan). So yesterday morning I set off for Home Depot, and bought a new Rheem with a 9 year guarantee. Right off the bat the old A.O. Smith wouldn't drain. There...

Well say you took a Timex / Rolex, (i.e. a mechanical watch), to 90% of light speed. Then what. What force is going to slow it down?

So a Timex or Rolex wouldn't be affected?

This is the thing that I have the hardest time wrapping my head around. That something mechanical can be physically slowed down by doing laps around Earth very fast. (17,500 MPH). And at that speed they pass over roughly the same place every 90 minutes. They're really not going anywhere. It's...

Infinity is hard to comprehend.

Well if it isn't what could be at the "end".... And what is beyond that?

So... If I drive fast enough to go and get my new water heater, it will already be installed by the time I get home. I better take the HEMI!

That brings up another hard to understand pitch...... Space is infinite and endless...... Everything else has a life. A beginning and a end..... Except space. It goes on forever.

But if you are traveling away from a source of light at the same speed it is traveling at you, how can it reach you? By the same token, if you are traveling AT the same light source, it's coming at you at a combined double the speed. A bit like that whole deal of a 12" ruler only being 6"...

So..... If you were in your car, traveling through space at near the speed of light, the stars you look at through your windshield would be twice as bright as you bear down on them. While the stars in your rear view mirror would barely be visible because you're out running their light.

So these people who are on the ISS for almost a year have slightly increased their lives by a measurable amount? (17,500 MPH for close to a year).
