    Default Leaking pressure gauge question Part 2

    I understand the liquid-filled gauges help to prevent the needle from "quivering" while in use. The question is do all RO's have liquid-filled gauges on them? The needles would move that much without the glycerin?

    I was thinking that maybe the solution to leaking gauges is to not use a gauge that has leakable fluid in it to start with. But I don't know if all RO's require glycerin gauges. Any thoughts?

    What style gauge does your RO have? Filled or unfilled?

    No comments on my gauge question? Are glycerin filled gauges standard equipment on all RO's? Just curious.

    Thanks Tim. I did vent the gauge correctly. Apparently, I was the unlucky recipient of a leaker. I'll purchase another one and hope it has a little more longevity. -Steve

    To answer your question about non filled gauges, on an RO the needle would flutter back and forth so much you would have little if any idea what the pressure was. Just my opinion, but I think the unfilled gauge would self destruct from the needle jump.
    Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
    Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
    Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
    After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
