My water heater has a 3/4" copper pipe from the T&P valve extending

Obviously it would be easy if I used some kind of flexible hose rated
for high temps. Is there anything wrong in doing it this way? How is
it usally done?

What kind of floor do you have? *If it's concrete I'd probably just

The answer may depend on your local codes. * There is a code in

use a pan under it that would catch both the TSP water and any

IIRC the code says no unions in the line (which is really
inconvenient) and specifies the number of bends and total OAL of the
line. I was looking into this at my last place because I wanted to
route it into the deep sink, rather than onto the floor (which had no
floor drain.) Of course it failed before I got a round tuit, on the
upside all that hot water did a nice job of loosening the hideous peel
'n' stick tiles that I'd been meaning to scrape up anyway.
