A number of people have complained about their pressure gauge filling with water when used and gave a poor rating as a result.

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.

I used the water pressure gauge to check my home water pressure prior to installing a hot water heater and expansion tank. It is important to know the home water pressure so you can adjust the air pressure in the new expansion tank to the correct cold water pressure psi. Expansion tanks come charged with air, so adjusting the the expansion tank air pressure is not always necessary. The cold water inlet pressure psi should equal the expansion tank air pressure psi. The Rain Bird P2A Water Pressure Gauge worked perfectly and the price point is excellent. The cold water inlet pressure can fluctuate. Follow the directions that comes with the hot water heater and expansion tank. Use this pressure gauge on a home cold water faucet with a hose connection. Follow the directions that are enclosed with the pressure gauge.

I bought this Rain Bird P2A Water Pressure Gauge because I need to measure the water pressure in the house before deciding on various types of Reverse Osmosis (RO) water filtering system. If your water pressure is above 45 PSI, then you can buy a RO system without a pressure pump, which is more costly.

This water pressure gauge is great. I attached it to the faucet that normally connects to my washing machine's water inlet via a rubber hose. You must install the provided O-Ring correctly so that there will be no water leakage. There is no instruction on how to do this. You should tighten the gauge to the faucet using a wide-opening plier.

If you get water inside the meter face, it is not normal. You should get it replaced. This does not happen to mine. As stated on the web page, this thing is NOT returnable because it is a closeout item.

I have copper plumbing throughout the house but water pressure was low inside the house, i.e., could not use 2 faucets at the same time. Then I adjusted the "Pressure Reducing Valve" on the supply line and got enough pressure. I wanted to check the water pressure to make sure "Pressure Reducing Valve" is set to the right level. So I bought this unit (instead of paying a plumber to just check water pressure!).

I connected the gauge to a garden hose hookup point, and it showed 112 psi. I was pretty sure that reading is wrong. Anyway, I adjusted the Pressure Reducing Valve all the way to the lowest pressure and confirmed water pressure was in fact very low at kitchen and bathroom faucets. Then connected the gauge again, and it showed 112 psi. It always goes up to 112 psi and stops irrespective of the water pressure I set.

Update: Apparently the water pressure reducing (PRV) was malfunctioning. After sometime water pressure at home became very insistent. Finally, I replaced the water pressure reducer valve. It cost me a good money for the parts and labor. Now the water pressure is under control, and the gauge show the correct reading. I adjusted pressure to 55 psi.

Received what I thought was a higher quality than I ordered. Thanks! Gauge was what I needed for an occasional check of my water pressure.

Just screw this onto any standard male threaded hose end or 3/4 threaded pipe end and you get a pressure reading. Seems to be solid construction. Has a rubber washer for a pressure fit and no tape needed.

Does what I needed it to do. One recommendation for this (or any other gage), is to attach the gage to an empty hose and hold the gage vertical so water does not enter the gage itself. The pressure will be the same due to the laws of physics and the gage will not be exposed to the water and damage from freezing it you live in the northern states like I do.

This little gauge will save your hundreds of $! I kid you not.
I had been experiencing plumbing problem with my house where we purchased new 5 years old. First, the toilet starts to leak (meaning the valve doesn't shut off the water and over-flown) then the dish washer valve leaked... then the shower valves... then, eventually, our water filtration system burst and destroyed one of the walls in our garage. If we would have purchased this gauge and check our pressure periodically, we would have avoided all the above problems! When the gauge showed that my house's water line pressure was 140 psi, I couldn't believe my eyes and I first thought this gauge was broken, but after confirming with my neighbor's pressure, I was so nervous about the pressure and had the regulator replaced within 24 hours to prevent further damages.
If your shower makes you feel really good with all the water pounding on your back, get this gauge and check your house pressure! Because that's what happened in our house! The water pressure sucks now but it could save us money on water bill... especially during this drought in California.

This Rain Bird pressure gauge replaces a four year old unit that I had. The old one was destroyed by curious children and a hammer. This unit allows you to tighten the gauge to the faucet with the ability to keep the dial in view. My older unit dial rotated as you tightened and many times pointing down or away from me making it difficult to see the pressure. The unit is very precise, easy to use and very responsive. The pictured product is a little different than what you receive. The actual product is much nicer with a display that shows psi and kg/cm2. It also has the Rain Bird logo on it - Made in China :)

I planned on adding a dripline system to my backyard but I could not figure out what my current water pressure is. I tried the old timing method of filling up a bucket in a minute with a stopwatch, but water would always overflow the bucket.

I found this product that would determine the exact amount of pressure that is coming into the system. The pressure gauge itself is made out of high quality materials (steel/iron) and feels solid to the touch. It has a simple and easy to read display that will tell you exactly how much pressure is in your line (up to 200 psi). The female adapter fits over a ¾” brass male hose, so if you have any other size hose this product will not work for you.

After taking it out the packing materials and plugging the pressure gauge into the line I checked it. My pressure was normal at 65 psi. I looked around to buy some pressure reducing valves and hooked it up to my dripline. If anyone needs to find out the exact amount of water pressure on their line, this is a valuable tool.
