Is this "Evap Rinse" thing real?

I saw someone on here say that if you suspect a faint positive may actually be an evap line, that you can use the same test again, but with water instead of urine, and if it's an evap line, the line will go away, but if it's a faint positive, the line will stay. Is there truth to this ladies?
