	????, can't be, is your gauge branch off the stream, or is the stream in direct line of the gauge? __________________ “ When people get what they want, they are often surprised when they get what they deserve " - James Wood

	Only way it could be is if he's referring to different circuits. The outlet pressure on the cold side could be higher than inlet pressure on hot side, or vice versa. Cheers.........Codey __________________ Give masochists a fair crack of the whip

	It could be the outlet diameter is smaller than the inlet, might want to check that. __________________ Charlie don't surf.

	that would only increase velocity. __________________ “ When people get what they want, they are often surprised when they get what they deserve " - James Wood

	What I like to do in such cases is have one gauge hooked up to both locations. A double inlet single outlet valve will remove any questions about gauge accuracy. It makes a simple hookup, and both readings are taken at the same spot. __________________ mike k
