A: It should measure the pressure. What it won't do is show a drop in pressure if the backflow prevention valve is really tight as the higher pressure at the gauge won't relieve back into the system if the pressure in the house goes down.
A: I think what is happening is that there is little or no friction on the red needle so if the black needle moves fast, it will bounce the red needle higher than the actual pressure.
A: The easily rotated red needle is a marker you use to analyze pressure changes. It is not meant to gauge water pressure. That's the job of the black needle. However it is so loose I found it to be of little help and simply wrote down the indicated pressures during checks throughout the day.
A: Yes, this would be correct as it is sensitive to water pressure.
A: Yes, you should. It may be hypersensitive base on the orientation of the gauge. Don’t expect it to be an exact, more of an in the moment close estimate.
A: Hi, I don't think so. In my tests, there was no water in the dial itself.
A: No, it is not normal for water to appear inside the gauge. A gauge with water inside the gage housing or display would be considered to be defective.
A: Hello Bobby, Yes you can use this with air! Thank you
