I'm totally re-doing my bathroom and shower. I tore out the old shower
2 months ago, re-routed the plumbing, and capped off the pipes. At this
point I am ready to install my new shower mixing valve but I don't know
which pipe is hot and which is cold.

Are there any tricks to identify which is which short of uncapping the
pipes and letting the water fly??

Thanks!

Hmmmm. Have someone bang on each with a hammer
whilst you listen at some junction.
