Things to Consider Before Buying a Water Pressure Gauge

After going through our list of reviews, you’re probably wondering which one is the best water pressure gauge.

Well, it is not that easy. While you can already have a good idea of what to go for – it is still necessary to learn precisely what to consider before buying. And for that, you’ll have to learn about the different factors that make a pressure gauge.

Here are some of them:

Types of Gauges

First off – consider the type of gauge you’re buying.

Many people don’t know this, but there are several models to consider – many more than the ones we talked about here.

Bar Only

As the name says, it only works with BAR pressure readings. This is the standard readings for the UK – yet you’re likely to find it anywhere in the world as well.

PSI Only

It is the standard in the USA – PSI readings let you know how many PSI the system is working at. These gauges don’t come with any other type of measurement.

Bar & PSI

If you’re a more versatile user who wants both – then you can get them. A PSI & BAR model will offer the chance to enjoy both types of readings, making it even easier and accurate to read pressure.

Digital

For the easiest type of readings, you can always get a digital water pressure gauge. You won’t have to depend on a needle that moves – this one will let you know directly with numbers.

Lazy Needle

Then you’ll find the lazy-needle models. These come with a needle (usually red) that moves to the highest point of pressure and stays there. It is ideal to know how far the pressure went in a specific amount of time (e.g., at night). This is ideal for plumbers & homeowners who want to check their water systems.

Duplex

The duplex gauge comes with two dials instead of one. Most of the time, it comes with one dial for PSI and another for BAR. Others may come with temperature and/or different types of readings for extra usability.

Liquid-Filled

For those who want a durable product, the liquid-filled dial comes like the way to go. These stay working correctly even in extreme temperatures, with high-pressure systems, and with the thickest of substances.

Liquid-filled gauges are ideal for demanding operations that demand something more resilient against vibrations, pressure peaks, and extreme environments.

Mount Size

The mount refers to the size of the threaded connection. Here, you’ll have to make sure that it fits with the piping and/or object you want to install the gauge with.

For example, in most residential pipes, the connection is 0.25-inches. That would be the standard size for most gauges. But some of them can be 0.75-inches in size, which is a little different. You may also find 0.5-inches connections as well.

For the best experience, we recommend finding a pressure gauge that offers adapters for all connections, if possible. That will make it even easier to make it work in any place.

Pressure Range

As we explained before, most dials come with either BAR or PSI – some of them come with both.

But it is not only the type of reading you have to consider but how much.

That means going for a gauge that offers enough PSI or BAR levels for your needs. Some indicators can go from 0 to 60 PSI or 0 to 4 BAR. But other models can go as far as 200 PSI or 14 BAR.

You’ll have to make sure that you’re getting a dial with the right pressure range depending on your needs. For regular residential use, around 100 PSI or 7 BAR will be enough. But for commercial use and/or heavy operations, then you’ll probably need at least 200 PSI or 14 BAR.

Construction

Lastly, you’ll have to consider how durable the gauge is.

Here, you will need to go over the materials used in the design of the piece as well as the type of construction.

For example, most gauges are made of plastic with a plastic window and a brass connection. That will be the standard and affordable pressure gauge.

But in some cases, you may find high-end models made of stainless steel with a polycarbonate lens and copper connections.

Apart from the build, you will need to consider liquid-filled models. These can come with all the previous builds, but with additional vibration & pressure protection. You may find them ideal for the heaviest operations out there that demand way more resistance.

How to Install a Water Pressure Gauge?

So, are you struggling with the installation of the water pressure gauge? Or are you just not confident enough? Well, don’t worry – here we’ll teach you how.

Just follow the next steps, and you’ll be able to get the water pressure gauge installed in almost any place.

1. Decide Where to Install

First off, decide where you want or need to install the gauge.

Of course, it is crucial to find the right location before doing so. But it depends heavily on the type of connection you’re doing (whether it is for water tank, for water lines directly, pumps, etc.).

For the best results, we recommend installing the gauge close to a water tank or water pressure regulators. Especially on residential supply systems, it is necessary to be close to where water comes from.

Lastly, make sure that wherever you’re placing the gauge – there’s a tapping plug or available accessory connection. This is a small entrance that lets you connect things to pipes from the side. Without this, you will need to disassemble the entire pipe systems and install a tube with one.

2. Turn Water Off

After knowing where you’ll install the gauge, you will need to turn the water off. Do this by closing the main supply valve will prevent any water from coming through the system.

Remember, you will disconnect pipes and so on, which could mean uninstalling entire pipe systems in some cases. For that, you’ll want no matter passing through.

Then, drain every pipe you’re disconnecting and the pressure regulator as well as any tanks. This will prevent any mess while working.

3. Prepare the Pressure Gauge

You’ve already found the right place for installing the water pressure gauge, and you’ve drained the water off the pipes.

Now it is time to prepare the device itself for the work.

Here, we recommend not only making sure the gauge is prepared for installation, but also finding any adapters and/or extra fittings for it. If you need a mounting base different to the mounting size on the gauge, then look for one.

Then, you can start wrapping up the threaded mount with Teflon. This is essential if you want to prevent any type of leaking from the base of the gauge. Especially in high-pressure systems, having Teflon-covered mounts will be crucial.

For the best results, we advise avoiding the use of sealant compounds. You may find it useful to prevent leaking, sometimes even more effective than Teflon. But these sealants can sometimes leak into the center of the gauge and/or pipe and cause clogging over time.

4. Remove Tapping Plug

A tapping plug is a small screw-like part that goes into pipes. It is located on the sides of tubing and it has the primary purpose of closing these entrances. The threaded hole where these plugs go is the place you install a pressure gauge.

To do this, simply remove the plug by hand if possible, or use a small wrench accordingly. The cap should come right off by unscrewing it off the pipe.

If there’s any water coming off, it means you didn’t remove all the water from the piping system before. In this case, just screw the plug back and then go and drain the water off the system.

Then you can proceed to clean the hole where the plug was. In some cases, these plugs leave some corrosion. Clean all that up and make sure it is ready for the gauge to mount in.

5. Screw the Pressure Gauge In

Once you’ve found the plug and taken it off, then you can proceed by placing the pressure with Teflon inside.

If you need a mount, base, or adapter, then install it first. Then set up the gauge over.

Do this by using your hands first. Make it tight enough but adequately screwed in. Do not go crazy installing the gauge to do it fast and end up with a poorly installed one. Remember, you’ve used Teflon, so it is essential to do it calmly and precisely.

When the gauge is tight enough that you can’t do it with your hand anymore, then you use a wrench around the base. This will help you tighten up even more.

Do not over-tighten, though. Stay safe to prevent the base and/or pipe from breaking. And what’s even more important, never use the body or dial of the gauge to tighten. Always use the base to prevent any unwanted damage.

6. Restore Water Supply

By now, you should have the pressure gauge ready on the pipe. You can proceed to open the water supply again, to let water in.

Open valves, pumps, and other parts that make the water flow through the piping. Make sure the water is flowing through as it usually would by checking faucets, hoses, tanks, etc.

If it opens correctly, then you can proceed to do the last step.

7. Check & Test

With the water supply open, then the water pressure should start giving reads. Here, you’ll have to make sure that it provides accurate readings.

But you will not only have to check for the readings but also for any leaks around. Especially if you had to disassemble any part of the piping system, then you must check for leaks. If there aren’t any, then you’re ready.

By now, the pressure gauge should be working correctly, giving you all the readings you need. And if there’s no leak – then you can rest assured that you’ve installed a water pressure gauge like a master.

How to Check Water Pressure?

Whether it is a well pump pressure gauge, a tank gauge, or a standard gauge for your pipes – you need to know how to check it. Otherwise, there’s no point in getting one of these.

That’s why we’re going to help you out by giving you a few tips & steps to follow if you want to check water pressure correctly.

Step-by-Step Water Pressure Check

Here’s what you need to do:

1. Install the pressure gauge (follow the previous section). Once done, you can follow to open any water supply and/or valve.

2. Make sure no one is using faucets, showers, or any other similar object at home. To test the pressure, everything should be closed.

3. Then you can proceed to turn on the tank, pump, faucet, or hose close to where you connected the pressure gauge. Open the valve all the way for the highest pressure possible.

4. This will let you know the pressure that passes through. Read accordingly.

This will give you an idea of what pressure you’re working with on the piping. Still, there are many other things you can do to make the readings even more accurate for your needs.

Tips for Precise Pressure Readings

The following tips will give you an even better idea of how to get the most precise readings when measuring. If you don’t want a single PSI or BAR out of the gauge readings, then pay attention to these tips:

·         Always choose pressure gauges that have a reading capacity at least twice as much as the residential pressure of your area. For example, if you live in a neighborhood that usually has 50 PSI of total water pressure, then you should get a 100 PSI gauge at least.

·         Reading the gauge is not only about the accuracy of the piece but also about how large the dial is. If you have a pressure gauge that has small numbers and sticks, you may not be able to read the total PSI accurately. For that, choose large diameter gauges that let you read with ease.

·         Opening water valves & supplies all at once may break the pressure gauge. To prevent that, open one valve first, then open the supply, and keep going with care. If you open everything at once, the pressure can be too high and over-charge the gauge, which could break it.

·          Test the pressure at least two times. Even though pressure gauges rarely provide inaccurate readings, it may not give perfectly precise ones in just one test. That’s why we recommend testing at least twice to make sure the readings are correct.

Follow these tips, and you may end up with a perfect pressure read. Don’t waste your time doing it any other way.

Conclusion

So, are you ready to make your final choice? If not, don’t worry. We know this can be a little confusing and somewhat tricky.

But we’re here for you.

That’s why we’re recommending the Flow Doctor All-Purpose Water Pressure Gauge Kit as the best option in the entire list. If you want a quality pressure gauge that fits almost anywhere and still lasts a lifetime – then this is your way to go.

Still, if you want something slightly more resilient, but that is still decently affordable – then pick the Gauge Liquid Filled WOG Pressure Gauge.

Whatever you go for, remember that the best water pressure gauge is the one that matches your demands above anything else. Choose following that idea, and you won’t regret buying your new pressure gauge.
