    0 psi on lower pump setting and 23 on highest pump setting

    I replaced my pressure gauge valve two months ago and thought the new gauge didn't register low enough (it was the only one my local plumbing store carried and I didn't notice until installed that it started registering at 20 psi) with a new one bought from TFTest. It registers 0 when I have the pump running at 1000 RPM and 23 when running at 3450 RPM. Any reason why this would be?

    Thank you in advance.

    Normal operation. So get your baseline clean reading at high speed so you know when to backwash.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
