Customers are dissatisfied with the movement of the electromechanical gauge. They mention that the needle is much too loose and tends to move with the slightest bump. The pointer is very lose and just moves around randomly. They also say that the red indicator hand moves too easily and gets flung all the way. Customers also say the maximum pressure dial is very easy to move and the red hand just floats around.

"...shows pressure variations greater than they really are because it moves too far and too fast with minor pressure fluctuations...." Read more

"...My only issue is that the high pressure needle moves very easily, so you have to be sure to read the level before touching the gauge." Read more

Great for RVing

Reviewed in the United States on November 19, 2015

Verified Purchase

Works well, and is accurate. The red max pressure needle is very easy to move, but it has to be or it would keep the black needle from reading accurately. This gauge has the swivel connection so you can turn it in any direction and then tighten it down, a plus for being able to see it conveniently. The housing around the meter is not water tight so if you attach the gauge to a faucet with the stem up, some water will run into the gauge housing when you remove the guage. Overall a great tool for checking water pressure when we are RVing to determine if we need to use the water pressure regulator.

This review is for: "LDR 020 9645 Pressure Gauge, 3/4-Inch IPS, 200 lb. Pressure"

The gauge worked very well for me. Some reviewers mentioned that the RED placement marker did not maintain its position which is supposed to show the highest pressure reached in the reading session. The RED maker on the unit I have works perfectly.

Overall a great product that is quite useful to have around.

Reviewed in the United States on August 14, 2012

Verified Purchase

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.

Easy to use pressure gauge

Reviewed in the United States on April 15, 2020

Verified Purchase

High water pressure is not good for the housing pipe, and very bad for the appliances' and toilets' water hose. Just out of curiosity I ordered this one and installed it at an outside spigot so in case there's a leak wouldn't be an issue. Installation is very easy. I utilized the quick connect on the spigot and this pressure gauge. I also taped the quick connect thread before I screw on the pressure gauge. I reset the red needle and turned on the spigot and got 80 from the gauge, and left it on overnight and see if it ever went up. The next day the black is still reading 80 but the red bumped up to 85, so there was a very small pressure spike. There's no leak so it's good. Overall it's very convenient to use. I do not intent to have it permanently installed (explained the quick connect). Simply bought it to learn the water pressure and justify the need of a water pressure regulator.

Was easy to install on the blowout pipe for our irrigation system. The threads were the perfect size for that -- they do not work on the normal hose bib and the connection leaks like crazy there. I have no way of really knowing the accuracy, but it appears to be about right. The max needle is great and shows how high the water pressure gets at night when I'm not looking.

Doesn't work at above 80 psi. Beware before buying!

Reviewed in the United States on January 12, 2017

Verified Purchase

The gauge I got leak water at around 80 psi - it was rated at 200 psi. I use the item to test the over night pressure fluctuation on my home hot water and main line. At first it appear to be working because the water line pressure was at 60 psi. However, I noticed there were water INSIDE the gauge glass after the first night and on the sink. I check back multiple time during the day and noticed that water started to leak from the gauge when the pressure move above 80 psi. This item is defeated and would not give me an accurate reading of the pressure - it's advertised function.

WARNING: If you decided to buy this item and you're using this gauge to measure over night hot water thermal expansion or main water line pressure fluctuation. Make sure you do this on a sink or some place where water can drain. If you get a defect like I did and connect this to some place that doesn't have a way to drain water you will get a flood.

Useful and inexpensive. I was quoted by an exoert of a popular plumbing company that I had 'high water pressure' in the house, leading to many possible complications. How much to fix it? The quote was close to US$400.

I purchased this water pressure gauge for less than $10 ;and tested myself -outside and inside, without any problem in less than 10'. Result: the pressure is normal -around 40-42 lbs/sqinch, and I can check it any time I want.

Pls, do not let this happen to you. Another job was quoted close to $900, life guaranteed. Although the tech offer several options, the lowest $390 if i supplied the materials. I found what was need for about $100, and the installation costs $125.

Works well. Will save us tons

We had water hammering in our house. We hooked this doodad up to the taps and saw that our pressure slowly climbed to 140 psi (way to high) when we turned off all our taps. This thing let us know that our pressure regulator needs replacing which will save us thousands in new appliances and plumbing repairs in the long run.

Fácil de instalar

Reviewed in Mexico on October 22, 2018

No requieres nada adicional para instalarlo, solo tienes que conectarlo a una llave y podrás medir la presión.

Las piezas se ven resistentes, no hubo fuga de agua. El adaptador de .25" a .75" con el que viene, está unido con el medidor con una especia de resina, supongo que es posible despegarlo para usar ese adaptador con otro medidor de presión, como los de 30 PSI, ya que estos es difícil encontrarlos con el adaptador a .75".

La aguja roja es el indicador de la presión máxima registrada, este se mueve manualmente a cero y cuando la presión esté presente, la aguja negra empuja a la aguja roja a la máxima presión que registre.

Excellent quality!

Reviewed in Canada on April 18, 2019

This is a handy inexpensive tool that measures water pressure simply by screwing it into an unused faucet. I like the secondary needle that can show you how high the pressure went up to. This is handy as you should let this sit on your line for at least 24 hours to get a good reading and find out what the maximum pressure was. A good pressure range for the average home should be between 50 and 80 psi. If it goes above 80 psi, then you need to install a pressure reducing valve and an expansion tank to protect your plumbing lines, water heater and all the fixtures.
