    When designing a new system, how do you check GPM? I was taught the 5 gal. bucket method, but it just seems kind of low-tech...

    There are a couple of more accurate methods, one inexpensive, one pricey.
    The cheaper one is www.betterwaterind.com
    Click on "Sentry I Flow meter.

    For balls on accuracy, we have this, which is battery-operated. Hooks up
    to a Data Industrial flow meter with pressure gauge & throttle valve.

    I still use the one in the picture-link below. Simple Toro pressure/flow meter. It's not too awfully accurate. But if you follow the directions it gives you a pretty good idea of what the flow is. I don't depend on it for perfect accuracy. But having used it for so many years now I can get a pretty dang good idea of where the flow is at 30 psi.


  9. I put my hand under the faucet at full blast.
