Water pressure gauges are simply tools to help you read water pressure. You can use a water pressure gauge to measure static water pressure, well pressure as well as pressure for sprinkler and irrigation systems. Water pressure gauges can also be used to identify leaks in plumbing or gardening systems, as well as detect a dip in pressure due to unusual deposits found in pipework.
You will never find out if your water pressure is right until you get a new water pressure gauge. What is the best water pressure gauge though? We have here six great water pressure gauges from companies that include Flotec, Pool Supply Town and Rain Bird. We will take a look at their positive aspects as well as their negative aspects, and later determine which water pressure gauge is worth your investment.
Without further ado, here are our six water pressure gauges that we will be reviewing.

Recommended 6 Best Water Pressure Gauge Reviews
1. Rain Bird P2A Water Pressure Test Gauge
This first pressure gauge is from Rain Bird. It’s maximum PSI is 200. It has a secondary readout of up to 14 kilograms per centimeters squared. The coupling location is on the top of the gauge.
This is a gauge that is easy to read and can quickly adapt to any faucet or hose thanks to its extra thread adaptor. The threading makes it connect to ¾-inch male hose bibs so that it can either connect to the faucet in your backyard or your garden hose.
You can use this water pressure gauge to help you determine how many sprinklers you would need for a pressure regulator.
The design is rather simple, and there is much else much to it. Rain Bird’s water pressure gauge features brass coupling so that it can last a long time, especially when it comes to handling water and moisture.
The one flaw with this gauge is that water will fill it when you try to test it with a home faucet. This does not damage or ruin the water pressure gauge, as far as we could tell, but it can lead to concerns down the road. We could see water from inside the face.
Here we also found some best digital water pressure gauge, you can check it once.
2. Pool Supply Town Super Pro 80960BU
Pool Supply Town brings us another simple water pressure gauge. The gauge is two inches in diameter. This one only has a maximum PSI of 60. This water pressure gauge is made to fit most sand, cartridge and DE filters on brands such as Pentair, Jandy, Hayward and Waterway.
This gauge from Pool Supply Town has a brass mount that is just half of an inch in diameter. It will not connect to traditional garden hoses or faucets, which is unfortunate. This water pressure gauge does not come with a thread adapter, but of course, you can always buy one separately.
There is not much else to say about this water pressure gauge from Pool Supply Town. It clearly has its limits, from the maximum PSI of 60 to the lack of a thread adaptor. It does not help matters that they do not last that long. Homeowners tend to buy two or three of these at a time and are treated as spares.
3. Flotec Brands2O TC2104-P2 Well Pump Pressure Gauge
Flotec’s water pressure gauge has a pure, white face with both readouts of PSI and kilograms per centimeters squared. The maximum PSI is 100. The coupling location is on the bottom of the gauge.
This water pressure gauge is to be used with submersible or jet pumps for the pool. It not only monitors water pressure, but also the performance of a water pump.
The coupling is made of brass, for longer durability and consistent performance of the water pressure gauge. The gauge itself is made of plastic, as it the lens that protects its face.
Its connection size, however, is rather skinny, at a quarter of an inch in diameter, you might not have a manifold that can connect do this, and neither would your local hardware store have an adaptor for it, most likely.
4. Renator M11-0660R Water Pressure Reducer with Gauge
This is more complex than the other water pressure gauges thus far. This gauge in particular, from Renator, includes a brass gadget attached to it called a water pressure reducer.
If you are looking to achieve less water pressure from your hose or faucet, this is one way to do just that. The maximum PSI on the gauge is 160, which is a decent limit to have.
The brass reducer holds up to moisture and water well, and will ensure that the gauge performs consistently. Inside this reducer, however, is oil to combat friction of the internal workings so that it lasts longer than other water pressure gauges.
This water pressure gauge can connect right onto your ¾-inch hoses and faucets, so you aren’t required to get a special adaptor, as it already provides the fitting that you need.
Renator’s water pressure gauge also comes with a one-year warranty, something very rare for this type of product. If this product breaks down within a year of owning it, you could be eligible for a new water pressure gauge.
This is the most expensive of the water pressure gauges thus far. You shouldn’t expect to pay this much for just a gauge, but if you are intrigued by what else this product offers, we don’t see why you should not consider it.
Another setback is that the gauge can sometimes become inaccurate. When it’s not redirecting pressure, or even unplugged, the needle will not be at “0” like it is supposed to. Having an inaccurate gauge is like having no gauge at all, in this regard.
5. LDR 020 9645 Pressure Gauge
LDR Industries has a water pressure gauge that has a maximum PSI at 200. The coupling location is at the top of the gauge. This water pressure gauge is also available in limits of 30, 160 and 300 PSI.
This coupling is made of brass so that the valve can continue to perform well at an extended period of time. It comes with a ¾-inch hose adaptor so that you can easily hook this gauge up to wither a hose or your outdoor faucet.
This is a water pressure gauge that has been tested and approved by CSA (Canadian Standards Association). It can also take up to 200 pounds of pressure.
The red needle is something to watch out for. It is extremely loose. While trying to read it, make sure that you don’t bump it, jiggle it or shake the water pressure valve, otherwise, the needle will move, and you can get an inaccurate reading.
6. STAINLESS STEEL LIQUID FILLED GAUGE
Finally, we have a water pressure gauge from a business that is simply known as “Gauge”. There are two versions of this meter: One that has a maximum of 100 PSI and another with a maximum of 200 PSI. The one we are reviewing the gauge that has a 100 PSI limit.
This water pressure gauge can also read oil, gas and vapor pressure, so if you have other applications in other substances, like a fuel supply, you can also use this product to read its pressure.
The face on this water meter is two and a half inches in diameter. This is pretty big for a water pressure gauge, but you can see it better than other gauges from a certain distance away.
This water pressure gauge claims to make little room for error, with a 1.5 percent span of accuracy. This gauge intentionally fills up with water, and it will still work as intended.
The outer shell is stainless steel, with wetted parts of copper alloy. There is also a glycerin filling to suppress the effects of pulsation and vibration. The lens is made of polycarbonate plastic.
One thing that you need to know about this gauge is that the glycerin must be refilled every now and then. If you are planning to use this product frequently, it needs to have a good intake of glycerin to keep the gauge from shaking as it is reading water pressure. This could be an ongoing expense for you, unfortunately.
What To Know Before Buying Water Pressure Gauge
If you are looking for the best water pressure gauge that will last, your best bet is to build one on your own. However, it isn’t that easy. First, you need to find a good quality gauge and then adapt it the way you want.
The problem is finding a quality gauge that won’t freeze in the winter or wear out after a few months of usage. It isn’t worth a dime if it doesn’t give accurate readings.
In case you still have some questions about buying a water pressure gauge, here are some answers to frequently asked questions:
Why Do You Need to Use A Water Pressure Gauge?
In water treatment, air or water pressure is very important. For example, look at how a pressurized water tank works. Apart from the household tests, it is being used for a variety of things.
You need to check your house water pressure periodically. Too much might damage your pipes, too low means there is something wrong with the pressure system. Whatever the case may be, it is certainly a tool that you must add to your wish list.
Do I need a hose for a water pressure gauge?
While a water pressure gauge does not require a hose in order to work, it is worth having a hose as connecting one to the gauge will sidestep any trivial accessibility issues, as hoses typically have enough flexibility to work with even the most stubborn of fittings.
What is the maximum PSI that I need?
We really cannot answer this question for you, as everybody’s situation is different. However, for home use, many gauges have a threshold of 0 to 150 PSI as the standard.
Most home water pressures hardly ever go past 100 PSI, so this should give you more than enough head room to get a gauge that is not just accurate but easy to read. Yes, sometimes, it isn’t always the best idea to get the gauge with the highest PSI limit, as it can be harder to pinpoint the exact PSI.
Is a plastic lens or glass lens better for water pressure gauges?
Polycarbonate plastic lenses tend to be more affordable, which is why they are on most gauges today. A plastic lens, however, does not make the product low in quality.
Plastic lenses tend to be shatterproof, but can be prone to scratches. Glass lenses can be resistant to scratches, but can break if dropped. Choose the type that you think will work better for you.
How to Test Water Pressure at Home?
To test your water pressure at your house, you will need a home water pressure gauge. The tool will have a place on top where it screws on to the first faucet because that is where you will get the most pressure.
1. Make sure there is a washer on the back of your pressure gauge.
2. Tighten it well.
3. During this test, make sure no one is using any faucets in your house.
4. Turn your faucet slowly all the way.
5. You will see the reading on the test gauge.
Depending on where you live, you will see what PSI you are getting on the gauge. If you have a high-water pressure say, for example, 160 PSI, you need to add a pressure reducing valve. It’s also called a pressure regulator.
Tips for Accurate Gauge Readings
If you want accurate readings, here is a quick tip for you.
Go with a gauge size that is twice the expected pressure in your area. For example, if the max water pressure is 80 PSI, get a 160 PSI gauge. If you want more accuracy, get a bigger one like 200 PSI gauge.
It’s better to buy a large diameter water pressure test gauge for better quality movement inside. Also, having more divisions with larger dial face will allow you to read to 1 PSI or less directly.
Don’t just slam the valve wide open and throw full line pressure at the gauge. Either be kind to your tool, or you will over-range it. If it is only 100 or 200 pressure test gauge, you can literally trash it on day one.
If you see the needle being pegged hard, that means the calibrator is gone for good. If you want to avoid that from happening, slowly open the valve.
Watch the pressure build and also make sure to get a snubber for the gauge if you are using it on a line with pulsating pressure. That way, even if you buy the cheapest one or oil filled ones, or even glycol filled one, you can make them last longer.
Different Types of Water Pressure Gauge
Before you buy one, always read the manufacturer’s specifications. Some pressure gauges are only meant for testing the water pressure, while others are used to measure the pressure of gas and oil.
Types of Dial
1. Bar only dials: This type of scale reads only in bars, and you will see a lot of them in the UK because they only use this method for water pressure reading.
2. PSI only dials: In the USA, all of us use PSI readings for water pressure. This gauge has a dial that only reads in PSI.
3. Bar & PSI:Pretty self-explanatory. It has the best of both worlds and also a very useful tool. It saves you the trouble of having to convert the measurements. Because in some states, appliance manufacturers will state some recommended guidelines for use in bar or PSI.
4. Digital dials: This type of tool uses a digital display for easy reading.
5. Lazy hand needle dials: This type of gauge is extremely useful when you need to check the water pressure overnight. You can attach them for a long period, and lazy hand will move with the needle but will stay at the highest point.
This means you will be able to tell the highest point at which the pressure peaked. This is a must-have tool for homeowners that are worried their water pressure is spiking in the night.
Simply attach one of these and wait for the reading. You don’t have to stand around all day.
6. Duplex dials: It has two scales instead of one. This type of gauge is great for measuring dual readings. There is one scale for temperature and a separate one for pressure.
7. Liquid filled dials: If you want a longer-lasting gauge, fluid-filled dials are a great option. As you know, the two main causes of a gauge malfunction are water condensation and pipe vibration.
In the winter, your gauge can freeze and damage the internal mechanisms. Having a pressure test gauge filled with viscous substances will leave no room for ambient air and humid to enter. It will prevent condensation and reduce needle vibration.
Types of Connection
There are mainly three types of connections.
1. Bottom mounted connection
2. Back-mounted connection
3. Top-mounted connection
Choosing the Right Water Pressure Test Gauge
Let’s get the most obvious thing out of the way first. If you aren’t a plumber and only need a gauge for domestic purposes on odd occasions, you are better off buying a cheap gauge.
Some of the inexpensive models are fairly accurate, simple to use, and if by any chance they break down, you can easily replace it. Now let’s look at other key components of a water pump pressure gauge.
Choose a proper mount option before you decide on anything else. You need to decide how you are going to mount your gauge.
If you think there is limited space or it will be in an awkward position, choose the right mount option that you can get you easy access and a clear visual of the dial.
If you are in the UK, choose a pressure gauge scale of 0 – 10 bars, which is 0 – 150 PSI. This is for domestic purposes only. Professional users need more than that. However, if you feel like there is high water pressure in your area, go for 200.
Normally, the water pressure in domestic areas rarely exceeds 6 bars. However, if you want more leeway, and a better PSI reading, choose a larger diameter gauge with a better scale.
Bar or PSI?
If you are a professional plumber and move from places to places, it’s better to have a gauge that can show both readings. Usually, in the US, you will only need PSI readings. But just to be safe, buying a dual reading gauge will save you money in the long run.
Premium or Economy?
High-end water pressure gauges are available in a variety of pressure ratings and configurations. Some manufacturers will give you a stainless-steel case with a similar thread material, while others will feature only brass.
If you want to spend more, you can go with high precision liquid-filled gauges. For domestic use, that’s just overkill. You are better off with economic models.
The water pressure gauge that you need to buy is the gauge NEW STAINLESS STEEL LIQUID FILLED PRESSURE GAUGE.
We find the large face to be a huge help with checking the water pressure. With its 2.5 inch diameter, you can see what the water pressure it without crouching down or moving the gauge closer to you.
Speaking of moving, you typically do not want to touch a water pressure gauge when it is trying to read water pressure, in case you might move the needle by error. The glycerin inside of this gauge will prevent most vibrating or rumbling, so that the needle is as accurate as possible.
You will need to buy an adaptor separately, and buying glycerin could be too demanding, but this is a quality gauge that doesn’t seem like it has any signs of slowing down after just a handful of months. These reasons are why this water pressure gauge from Gauge is our number one choice.
