Although I don't have anything to test its accuracy against, I feel this item does the job and comes in handy for the do it yourselfer to check their water pressure every so often.

The reason why I purchased mine was because for the past few months I had suspected that the water pressure in my house was too high since the water would surge out whenever I turned on any faucet in the house. Being that I had no experience with plumbing, for $9 I figured it was worth a shot to see where things were at instead of calling in a plumber who would charge me for the trip to diagnose and then charge me again to return with the parts to repair the issue. Since I live in a duplex I was able to test the pressure coming out of my hose spigot and compare it to my neighbor's since they had their pressure reducing valve replaced a few years ago and I presumed that theirs was still functional. On my initial pressure test I got a reading of about 110 psi coming out of my side which would drop to 60 psi when I turned on a faucet in the house. When I hooked it to my neighbor's hose spigot and turned it on I got a reading of 60 psi that stayed constant even when I had them turn on a faucet in their unit. I tried to manually adjust my pressure reducing valve down as shown on various do it yourself websites and videos but it did nothing and given the age of the unit, it was safe to say that my pressure reducing valve need replacing.

I ended up buying a new pressure reducing valve and installed it myself and with the factory presetting on the PRV unit the psi was brought down to 60 and did not fluctuate when other faucets were turned on. With that being said, I'm pretty satisfied with this item.

Wonder if your water pressure varies a lot?
The black needle will push the red one to the highest reading,
making this unit very useful. Just screw it on a hose connection
turn on the water valve and check it as needed.

Nice item for the money. The red needle is handy for recording the max pressure. The red needle is very sensitive to vibration.
Made in China.

I bought this to check the water pressure on a sprinkler system. My gauge arrived with the red 'peak pressure' pointer trapped on the wrong side of the black indicator pointer (an idiotic assembly and QA error, thus minus one star). I fixed this with a pair of pliers, pulling outward on the central knob to lift the red pointer as much as possible, then forcing it past the stop pin counterclockwise. The red pointer twisted alarmingly before snapping past the pin, but returned to normal thereafter.

The gauge is not sealed where the black housing meets the brass stem (think of it as a dust cover), so expect humidity or rain to cause internal condensation on the lens and inside the housing. Indoors this will not be a problem, and the moisture will eventually clear when brought into dry air. If the internal mechanism is copper and brass as I suspect (I didn't open it) condensation should not cause any significant corrosion. A sealed gauge would be much more expensive.

Be aware that both the pressure and peak readings may be affected by water flow. Any water 'hammer' from faucets or sprinkler timers slamming shut may spike the reading higher momentarily, causing the red peak pointer to read higher than typical system pressure variations.

I did not experience any leaks with the gauge, nor did I have any problems with the peak pointer being too loose to hold its position.

The gauge was as advertised and seems to work well. My only issue (which I had noted from other reviewers) is that the red reference needle is much too loose and tends to move with the slightest bump, thus negating its usefulness. However, a pad and pencil accomplishes the same thing. For the price, it's a good value.

I purchased this because I noticed the water pressure in my home was high. Stuck this on a facet outside ant saw my water pressure was up to 160 psi. Called the builder of my home and got them out to replace the pressure regulator. Water pressure is now sitting at 65-75 psi and my water bill has gone down too. Great product, can be left on and used to see if there are any spikes in water pressure. Solid build, doesn't leak.

I have used this gauge a few times. I have no way to test or compare for accuracy, so am assuming that it is reasonably accurate. The red "maximum" pressure dial is VERY easy to move.....the slightest bump moves it, even gravity moves it. Would be nice if I could expect it to not rotate so easily.

Nevertheless, using my pressure readings, I adjusted the air pressure in my water heater expansion tank.

As a home inspector, I use these things every day. This particular gauge lasted about 15 inspections. Don't waste your money. Just go to Lows or Home Depot and pick one up if you need it quickly. Otherwise, there are better ones to purchase on-line for a little more cost. If you buy cheap, you can expect cheap.
