In this video, Mike from PRM Filtration goes over how to zero, or reset a liquid filled gauge by venting it. This simple process is sometimes required after these products are shipped via plane, as they experience a change in altitude and pressure.

Perfect - and thanks for making this a 2 minutes video, and not 20 minutes!

[@md122005]

Very good video!! Thanks!

[@MrSumgi]

Thanks for posting this video. Tghis is a great and simple fix for a nagging problem. It did work on one guage but...I have this problem with another guage and this solution did not work. Is there another work around or should I just buy a new guage?

[@jmackmcneill]

Perfect, the exact problem I had, and solution I never would have guessed. I thought I was going to have to get a new gauge

I have a carpet extractor machine with a gauge installed, my gauge is off and I burped it but it did not reset do you have anymore suggestions. Thanks in advance

One of my gauges connected to the fpr blew a hole in the bottom out the weep gasket. What could have caused that?

[@sharons9367]

If the gauge doesn’t have the plug can you drill a hole into it ?

[@agsensenz9464]

This didn’t work for me, is there anyway to take it apart and use the adjustment screws? I think the unit may been exposed to overpressure

The guage I got was like yours in the video, 3/4 full of glycerine. Should I fill it to the top or is that how it should be?

[@Karnage543]

Leave it alone. They're supposed to be like that so the fluid has room to expand when it gets hot. If it's filled to the top the fluid has nowhere to go so the gauge will start to leak.

Can you help? My 0-30 gauge is same as in your video. needle is sitting at 20, because outdoor temps dropped below freezing. So, it's not a question of burping it. Any other way to get that needle back down to zero? Thanks!

Can u warm it up inside or use it inside i spilled mine so i refilled but now it go's past 30 wtf

[@SelvaKumar-lp8qc]

Sir please help pressure no zero sir

[@jedidiah4004]

Thank you, I thought I received a defective gauge

[@robertingrassia2637]

I call bullshit.Does not remedy the issue

[@MikeSmith-cc4wf]

Well why don't you explain what the hell that sticker means it says to cut the top which if pressure is built up it could explode the glass so why did they stick a sticker saying to cut that nipple on the?
