It depends upon your plumbing system and the power level you're running.
Assuming you're tied to a metallic city water hookup, and you're running
a low to medium power system, tieing your RF ground to the incoming
watermain should be fine. The concern is with newer houses, where
portions of your plumbing system may be electrically isolated by
sections of high pressure plastic pipe.
BTW, you could bury the copper strap that runs between so that it
doesn't show (and in the process actually improve your grounding setup).
Safe grounding to you, Ross!
