Rain Bird P2A Water Pressure Test Gauge, 3/4" Female Hose Thread, 0-200 PSI. Easy-to-read gauge supplies water pressure readings from 0-200 PSI. The 3/4” female hose thread adapter quickly attaches to outside faucet or hose. Accurate measurements are critical to an effective irrigation system design; gauge accurately measures water pressure before design and during installation. May also be used to replace pressure gauges on all major brands including: Hayward, Pentair, Jandy, Zodiac, Waterway, Jacuzzi, etc. Rain Bird “The Intelligent Use of Water”

This is a common problem from on of two user errors:
* Not installing a washer into the gauge's hose fitting
* Improperly installing the washer into the fitting.
Inside the gauge's hose fitting is a hollow brass stem with a wide lip at the end. Often, people will incorrectly push the washer over this lip so that the washer surrounds the body of the stem, since the lip isn't that much wider than the inner diameter of the washer.
Doing so fails to properly seal the meter from the hose fitting, resulting in the meter filling with water.
As you can see in the attached photo (or the video at https://www.youtube.com/watch?v=Br5D_tx_YVI), the washer is supposed to sit *on top of* the lip instead of being pushed over the lip onto the stem.
When the washer is properly installed, the gauge should not fill with water.
Con: Apparently, for a product that tests water pressure it is NOT water proof! Gauge was connected to hose spigot. Spigot dripped water onto the gauge at the point where the brass material meets the gauge. There appears to be a gap around the fitting that you can stick a fingernail into. This is a poor design, as it was water entering my old gauge that destroyed it over time.
Overall, I do not recommend this gauge if you expect your new gauge to last a long time.
I plan on verifying the source of water entry, if I am correct, I may try to seal the opening myself. If water is entering internally, I will have to return as a defective item.
The meter's range is 0-200 PSI, or 0-14 kg/cm2.
The fitting is brass, the meter housing is black colored metal, and the meter face appears to be glass.
The meter can be used in any orientation, although the markings on the face are only going to read correctly if the meter is hanging down from a spigot or other fitting.
The inner throat of the hose fitting passes through to the inside of the meter. The included rubber gasket is just like any other flat garden hose gasket, and it both seals against escape of water passing through the fitting, and also prevents escape of water outside of the fitting. Accordingly, both faces of the gasket must be in good condition and also properly positioned inside the hose fitting.
I read numerous complaints about this meter, with the face of the meter reportedly filling up with water. My own observation is that the face of the meter behind the glass is basically open to the air though an opening at the top of the meter housing, just below the brass hose fitting. If the hose fitting's gasket is missing, or improperly installed/positioned, or just damaged or worn out, water may leak out of the hose fitting, and will run down the fitting, through the opening in the meter housing, and into the face of the meter. I suspect that most complaints of this nature are the result of improper gasket functionality. Having the fitting too loose will also allow water to leak, and of course it will run down into the meter face.
Since this meter is intended to temporarily check water pressure at a spigot, which only takes a few seconds, it should be pretty easy to get a pressure reading and then turn off the spigot valve and remove the meter before much, if any, water can leak down into it. And if you notice any water on the meter face, just upend the meter after it is removed from the spigot and let the water drain out.
This seems to be a functional product of decent quality. I would recommend it for any home/garden/light industrial application that involves temporary measurement of water pressure at a spigot or faucet.
By the way, I saw a couple comments where people thought this meter was faulty because the pressure reading dropped when another nearby faucet was opened. That is not a fault of the meter, because the physics of fluid dynamics require that pressure drops when there is flow. This meter can only read the pressure that is present at the spigot that it is connected to, and cannot reflect the pressure elsewhere in a dynamic (water is flowing) system. On the other hand, if the water system is static (no water flow happening), then the pressure will be the same at all points in the local system.
It wasn't until I borrowed high quality but Expensive unit from a plumber friend that I got an accurate pressure reading.
Helped me verify that high water pressures is most likely the cause of my frequent plumbing problems, premature faucet/fixture failures, and water hammer.
Now it's time to contact a plummer to install a pressure reducing valve.
