Title: Anyone test their gas pressure?
Post by: tedeboy on September 07, 2018, 06:59:41 pm
I really need to do this.
Specifically at the refrigerator.
You use a manometer correct?

Any suggestions on what to get and how to test it?

Thanks

You can use a piece of plastic tubing and some water.  11" WC literally means 11 inches of water column.

There are quite a few youtube videos, like this one: https://www.youtube.com/watch?v=i4ROWQu2Xcs

If that method seems like a hassle, you can take it to a propane place and ask them to do it.  Their process will look something like this:  https://www.youtube.com/watch?v=X0dSSfSIayg

Looks like this would work?

I watched the video and was disappointed when I did not hear anything regarding calibration of the instrument used for the test. In my professional opinion taking any sort of measurement using an uncalibrated instrument is nothing more than a guess. If it were me I would contact the manufacturer of the refrigerator and ask them to provide specific information regarding how to test along with what level of accuracy is required.

For many years I used a tube manometer, once built, no additional calibration is needed.
It isn't an easy thing to carry and use but it is accurate.

A few years ago I found an inexpensive digital manometer and have found be to very accurate and easy to use.
Periodically I check the calibration of it against the tube manometer

FYI, not all regulators are adjustable.
This is another item that you need to know what you are doing, a mistake could cause an explosion or fire.

Thanks Larry.

I am certain the regulator has never been replaced.
Not sure of the lifespan on these but 23 years is a long time. It’s got a ton of use on it.

I found this one which looks like a good replacement.
