    Glycerin Gauge Question

    Ok, got tired of the El cheapo gauge that goes to 60 psi and my running pressure so low its pretty much impossible to detect a 20% rise. It was time for some regent refills from TFT anyway so I added the gauge.

    It was delivered today. It sure is purdy compared to the current one!! Nice and solid too!!!

    Ummm, but what's with this pull the plug and replug part? I hope I only have to do it prior to install because it will be horizontal once installed. Won't the glycern just run right out? Also, is the air bubble in it now ok, or is that what pulling the plug will release?

    I KNOW there has been a thread on this........and not sure if you need to do that step or not. I'll search unless someone with a better memory than mine chimes is.

    Hmmm, maybe? Don't cut the tip, but if you do it doesn't matter? Mine has the plug, but some ignore it and another thinks it needs equalizing frequently.

    Seems like it probably doesn't make a big difference either way.

    Re: Glycerin Gauge Question

    Thanks AimeeH I had searched but was obviously using poor key words. Finding a few others after the one you linked. Answers still vary but Duraleigh posted on a few of them to only worry about it when it's not reading zero with the pump off. Since it has a physical stop it looks like I only need to worry if it is reading some kind of mystery pressure with no pump.

    Re: Glycerin Gauge Question

    Well.......I have the same gauge and maybe you just helped me. I was getting wonky readings after a year so switched it out for an el cheepo. Still have it set aside. Now maybe I'll come back to it and I should have read instructions?

    This site seems to always have the answer, so if it relates to my pool in any way I seem to forget that Google is otherwise my best friend

    Great article here about it and I did see one reply on one of the threads it was more for any difference in atmospheric pressure.
