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

I'm not sure yet. Water does go up in the gauge. It seems to work okay outside of that and the water does drain out.Published 3 months ago by George H.
This gauge seems well made and works OK. Just to avoid any confusion, the OD of the NPT male connector is 0.5". The description makes it appear that it is a 0.25" OD. Read morePublished 5 months ago by Texas Skunk
Nice inexpensive water pressure gage with maximum/minimum resetable red hand. Red had can be used to record either maximum or minimum pressure. Read morePublished 5 months ago by DOUG
Good seal when installed... no leaks. Seems like not so great quality, but they have held up fine months later and are accurate and reliable. Read morePublished 6 months ago by Big A
