To dispell another myth, that was suggested about pressure, understand the corellation between pressure and volume. Just because the flow is high does not mean high pressure, or low flow does not mean low pressure . These are relevant to delivery piping sizes and distance. A small pipe with high pressure will give a low flow, a big pipe with low pressure will give a a high flow. Get it?
Static pressure, when there is no flow is the only proper measurement.

You're right, but the other poster is also correct that you can see that by opening a faucet. High pressure, low flow, will be seen at the faucet easily, when the water bursts out when first opened, and then peters off in a few seconds. Only a pressure gauge will really tell the static pressure story (which I always carry), but I don't bother using it unless faucet performance raises suspicion.
