Replacing the hot water heater...are flexible connectors any good, and

Sure, they're good. They make for very easy installation.

The EPA recommends a "heat trap" for in and
out going water; a flexible connector, basically, with a u-bend. Is
this a good idea? The local plumbing supply store guys scoff at
anything but sweat fitting and straight copper pipes. Also, how would
I know there's any problems with water pressure? About nine years
ago, I was talked into installing a pressure regulator, and I've had
nothing but trouble since. I don't have overly high (city) water
pressure; never had trouble before with anything. The house was built
in 1989. Why shouldn't I just take it out, and that way I don't have
to install an expansion tank? Any ideas, Joe?

Hmm. I though heat traps were valves to prevent convection losses. Sorry,
though, I don't have any information on them.

Why would you care if there's a problem with the water pressure? There's
nothing you can do about it.
