A Little Background

A hydraulic pressure test kit is used for excavation sites and excavation machines. These excavation machines can be hard to deal with the right amount of force, and this is why you need to be able to determine the amount of force using this kind of package. It comes with everything that you need and might work well for various brands of excavators such as Caterpillar, John Deere, Komatsu, Hitachi and the like, usually with quick connectors.

They usually have 3 gauges of connectors. The 3 gauges are all important and come with the whole package for determining the force of water that comes through the system. The different kinds of forces are measured in psi, a standard unit of measurement that determines pressure or force. This unit can determine which force connection or gauge you should use for determining and working on the item, especially if you are on the jobsite.

Most of them will have a pressure of 9,000 PSI at maximum. The force is important, but the force can vary depending on the included connectors, usually amounting to 3 pieces in each package. These three pieces can have different PSI measurements depending on what you want to determine when you want to use it for plumbing and excavation needs.

They will usually come in a handy case. The case will be most likely made of stainless steel material so that will not be prone to corrosion when you use it in excavation sites and plumbing jobs due to the water force and power. It will also make the components more durable when you transport it. However, the case should not be too heavy to carry around so that it is easily portable as a determining package for water force.

Most of the hoses will be 60 inches long. These hoses are usually flexible and are included in the casing, mostly having its own package pocket so that it will be easily organized. The hoses should be of high quality so that it will be dependable without possible leakage when you use it on the field, which is very crucial for those who work in the plumbing industry and want a dependable item. 60 inches is mostly the standard length.

It is important to have a unit that can be compatible for different brands with its quick connecting parts. We mentioned these brands before, but this is also very important in choosing the right gear before you head on to your jobsite. You have to know the brand of your excavator first to make sure that your unit for determining the water force fits perfectly with its quick connectors to avoid wasting your money.

How we Picked

In choosing the best hydraulic pressure test kit, you should know about the following:

Maximum working pressure: the maximum working force of most standard water force determining package is around 9,000 psi. However, units that are designed to be used for really extreme purposes or industrial applications may have a higher force tolerance of up to 10,000 psi to keep the force controlled well in these situations.

Gauges of measurement: you have to consider at least 3 gauges for the water force determining package on its measurement so that it will not be troublesome for you later on to check on the system. These gauges can vary in forces so that you can fit them in depending on the kind of force that is needed by your excavation tool, so that you won't run into any trouble later on.

Ideal use: the ideal use will mostly for excavation purposes and in the plumbing industry. However, there are also packages that are available for use for fuel injection systems and even for water filtration systems, which may also require such usage.

Durability of the casing: you should consider a water force determining package that has a casing that is made of stainless steel but should be easy to carry. Stainless steel can protect against corrosion and it can also help protect your inner components inside your water force measuring package so that it will not get broken later on.

Portability and lightweight quality: much like with the quality of the casing, you need to consider a water force measuring package that will not be too heavy to carry around. This is especially the case if you often travel and your excavation or plumbing jobsite is too far away, so that it can be easily accessible anytime and anywhere.

Ease of use: all of the components should be working like they should, and should be simple and straightforward. The hoses should have good connections and the quick connections to the other brands of equipment should be easy to connect. Each gauge should function properly according to usage.

Other Frequently Asked Questions

Q: What are the advantages and disadvantages of a water power system?

A: The water power system has a lot of advantages and disadvantages, such as the following:


1. It is very easy to control for most people. You can slow down and also speed up whenever you wish, and it will easily start the whole system. This is because it has sufficient levers that can be controlled, as well as the push buttons that will be simple enough for you to operate. This is highly important to consider, so that the operator will not experience user fatigue.

2. The force is quite a lot with just a few controls. The force is multiplied so that you can definitely use it with the simple mechanism that does not require levers, pulleys and gears as a fluid power system. It has good output that can amplify the force of whatever power that you have, even if it is only a fraction of a pound in terms of power.

3. The torque and the force are both equally constant. The speed change will do nothing to the force so that you can operate your equipment without going out of the flow. These fluid power systems make a difference compared to most mechanical and traditional means that can produce torque and force, as other mechanical means might not be very constant in their force and their torque.

4. It is very safe to operate and straightforward for most people. This is why most people who are still very new to operating a water power system will definitely feel at ease with it. This is because of the fact that the moving parts are not too complicated and not too much in number, which makes operating the water power system very easy overall.

5. They can save money in the long run. Because the system uses lesser numbers of parts that move, there will be less likelihood of getting damaged often, and thus, eliminating the need for repairs and such. This very fact makes water power systems very effective in comparison to electrical and mechanical systems out there.


1. There can be some fire hazard that will happen in case it leaks. The reason why it is not really a good custom to install a water power system when you live in a hot country or region of the world, is the fact that it can potentially leak and can also have fire accidents waiting for you later on. You should check your area first and the temperature before planning to install a water power system.

2. Injuries can happen when it comes down to operating it. Many people have been injured when it comes down to operating these kinds of water power systems, and this is why you should be extra careful when you are operating them. The products involved in them, as well as the entire system, due to the water power lines, can be dangerous due to the possibility of bursting or exploding, which can bring out terrible explosion debris.

3. They can be a bit of a mess to operate with. This is why not many people operate such a water power system due to the very fact that the oils that are used in the water power system can be messy when you are handling them and when you want to fix the leakage. Having the leakage on the water power system is the most frustrating thing that can happen, and this is why many people don’t try this system.

Q: What are the different types of water power systems?’

A: In general, there are two types of water power systems that are most commonly used:

Open circuit water power system

These kinds of water power systems use the power of pumps in order to operate. The force of the water power system is not too high in this case due to the mechanism of the pump, as the path to the tank is not as intense as the closed types. There is a control valve in the water power system that is set in the center part. This open center is where the flow of the liquid is returned from the tank.

The unique kind of water power system can be stacked due to its design, in which more control valves can work at the same time. The fluid or water goes through the force relief valve after a flow that is too high or a force that is too high on the water power system. In this setup, the pump gives an output that is constant.

Closed circuit water power system

This kind of water power system is different because its force is constant for all of the valves. The fluid from the water power system is very little because of the fact that the pumps have different rates of flowing, unless there is a valve that is actuated by the person who is controlling the water power system.

The return path is not needed when it comes down to the spool of the valve in this kind of water power system. The force and flow is very full when it comes down to this kind of water power system, even when the user is actuating the valves or just letting them stand by.

Q: What are the different parts of a water power system?

A: The water power system can have different important parts, such as the following:


This is the part of the water power system that holds the liquid. The usual liquid that is used in this part of the water power system is water power oil. Many people may find this part messy because it can be hard when the water power system oil leaks out, and it can also be hard to refill or replace.


The pump is the life of the water power system that feeds the liquid onto the entire unit. Without the pump, there would be no power at all when it comes down to setting up the water power system. Sometimes, when the pump  gets broken, all you need to do is to ask for a replacement part.


The motor is also the life of the water power system because without it, the pump would not function at all and the parts won’t move. It is important to have a durable motor that will have more lifespan than you think so that it will be of heavy duty and can be used for the many years to come.


The valves are also vital in the water power system, as they can control the direction in which the liquid will flow. The rate of the flow is also controlled by this component of the water power system, as well as the force, so that your system will work just fine.


The actuator is the part of the water power system that turns the liquid energy into mechanical energy. This is also a very important because it can provide the matter of motion that can make the rotary function do the work from the motor.


The piping is important in the water power system because it transfers the liquid from one area to another area, serving as the ways for the liquid to traverse through different areas of the said water power system.

Q: What are some most common misconceptions that come with water power systems?

A: Water power systems can be complex, and most people believe myths about them. Here are some of those misconceptions debunked:

“A water power motor and a final drive is essentially one item.”

They are not, because a speed reduction system is incorporated with final drives whereas water power motors are general terms for those systems that move fluid from one place to another and use the energy into electrical source.

“Water power systems are a new thing.”

Actually, water powers has been around in the 1600s and in the 1700s, from the concepts of Blaise Pascal and Daniel Bernoulli respectively. Water power motors have been made in the later years and are still being used today. The systems went through redesigning but still apply the same concept.

“You only need to connect the hoses in order to set up the water power motor.”

That’s not always the case, because you need to fill up the motor with water power oil in order to make it work properly. If there is no oil in the crankcase then the system will most likely get damaged. So, to wrap that up, you need water power oil first before connecting the hoses.

“Only miners, construction workers and industrial factories use water powers.”

Actually, many systems around us use water powers, such as roller coasters, movie SFXs, airplanes, convertible cars and the like.

“It is safe to use the yellow bucket water power fluid.”

Water power fluid should be used sparingly and checked depending on the type of machine that you have. Make sure that your water power fluid is definitely compatible with the said fluid, otherwise it will not function properly and may also put your gear into serious trouble.

Q: What are excavators used for?

A: An excavator is a type of heavy equipment that is used for the following tasks:


True to their name, the most likely use for the excavator is the use for digging through any kind of land or area, mostly for construction and the like.


The excavator can be used for the mining industry, as it has the capability to dig through anything, such as rocks, soil and the like, faster than normal mining techniques could ever do.


The one thing that makes the excavator very good is that it can be used in forestry, especially when it comes down to trees. With legal forestry, you can easily use them for large heaps of trees.


You can definitely use a excavator for construction. They are common in these areas for digging for land and building swimming pools. They are an all around expert when it comes down to infrastructure and road construction.

Pipeline industries

The excavator is also a very useful player and contender when it comes down to pipeline industries. Your local plumber will most likely have a mini excavator that will help with the installation of pipelines and the like.


The cool thing about the excavator is that it is not just for infrastructure, but also for landscaping. Ever want to landscape your own land that looks pretty ugly? Get an excavator expert to do the job for you.

Snow plowing

If you find it hard to get through the snow and it is really snowing violently in your area, the excavator can help. If you don’t have a snow plowing machine at hand, the excavator can do a pretty good job at plowing the snow as well, just like its other counterparts.

Q: What exactly is pressure?

A: Pressure is applied over any area or unit at a certain extent, and is described as power. It is a scientific term and has the formula:

P = F / A

whereas P = pressure, F = force, A = area

Force is most likely a positive value, unless you are talking about negative force in very rare cases. Force can be expressed in any of the following units:

a. Pascals (Pa or MPa

b. psi (pounds per inch)

c. atmosphere (atm),

d. bar or Bar

e. torr

f. N/m2 or kg/m·s2

g. msw or meters sea water

Q: What are the different kinds of excavators?

A: The excavator is not just one type – there can be many kinds of excavators out there, all with different functions, such as the following:

Crawler excavator

The crawler excavator is a kind of excavator that is used for softer soil due to its design for lower ground force. If you have an area that has very likely chances of sliding, landslides or slopes, this is the ideal excavator to have for your purpose.

Wheel excavator

The wheel excavator is a kind of excavator that is used on flat ground instead of in slope grounds. They have simple wheels like a regular vehicle instead of the tank like wheels of the crawler excavator so they are like regular vehicles.

Q: How does a water power system in a car work?

A: The process for the water power system in the car works in the following order:

1. Brake pedal – the brake pedal is connected to a small piston and is stepped on by the driver of the vehicle or car.

2. Small piston – the small piston is connected to the brake pedal and the force is driven to the cylinder after the motion has been set.

3. Cylinder – this part of the system sets the whole thing in motion, and is connected to the small piston and the brake pedal.

4. Brake connections – if you have other brake systems in the car, there can also be additional brake connections that form a branch halfway.

5. Brake fluid – the brake fluid is what gets the system going smoothly and to flow fluidly. Without it, the system won’t be effective and the brakes won’t work well.

6. Brake pad – the brake pad is found at the end of the cylinder, just after the brake fluid’s entryway. The brake pad ensures that the system works.

7. Large piston – if there is a small piston, then there is also a large piston. The large piston works to connect to the brake disc by being targeted by the brake pad.

8. Brake disc – this is the part that is attached to the wheel, and furthermore stops the vehicle when you step on the brakes.

Q: What are some of the common problems that water power systems often have?

A: Most water power systems are more complex than you think, and this is why the system can get some problems such as the following:

Force valves are not flowing right

This kind of problem happens when you can’t easily control the flow and it becomes confusing later on. The problem usually roots down to the flow control valve, in which you can get an expert to help fix if you don’t know much about the problem.

Not enough flow and power

Power is needed to have more flow, and this is why not all water power systems work because there is not enough power to drive the flow to the entire system.

Not installing a good rod

The rod is an important part of the water power system as it helps the double cylinders to work well.

Pump size being too big

You should know that the bigger the pump, the more force and power you need to move it, so be careful when choosing pumps for the water power system.

Sticking to a standard cylinder stroke

There are actually many variations of the NFPA cylinder for each stroke, so to each their own, because all systems can work differently.

Q: What is PSI?

A: PSI is a unit of measurement that stands for pounds per inch. It is a unit of measurement that is mainly used for measuring force or the amount of it. The following are the conversion specifics of 1 PSI:


Pascals (Pa)

Atmospheres (atm)






Q: What is the typical PSI of a water power gauge?

A: The water power gauge can vary in PSI, but the normal range is from 3,000 to 5,000 psi. However, there are also industrial units out there that can go for up to 10,000 psi in maximum. The amount of PSI in a water power gauge roughly depends on how it was built.

Q: What does accuracy mean?

A: Accuracy means the accuracy of telling and measuring the amount of force in a water power system, which can be from +/- 0.25% up to +/- 1.5% on the average. Accuracy is highly important in any measuring tool because it helps you determine that there is a smaller chance of margin of error when you are using this kind of tool or device to help measure your desired material or element.

Q: What does MPa mean?

A: MPa means Megapascal, a unit of Pascal that is much bigger. It is usually also converted into psi whenever needed, and is a unit of measurement for force as well. The formula for getting the psi from your MpA is: MPa x 145.0377.

Q: What causes household water leaks?

A: Water leaks at home can be caused by any of the following:

1. One of your lines have been clogged.

2. Instances of corrosion can cause leaks.

3. Some seals have been broken on water connectors.

4. Pipe joints have been damaged.

5. Water force is too strong.

6. Tree roots might interfere with pipe lines.

7. Connectors might come loose with your appliances.

8. Temperature changes can damage pipelines.

Q: Are plastic piping safe to use?

A: Yes, even though some people fear about plastic piping exploding and causing leaks, there are still some advantages and considerations that don’t make plastic piping harmful as much, such as the following:

1. You can get quality piping if it is adherent to the ASTM Standards F 876 and D 3309 standard specifications. Both of these certifications ensure that your plastic piping have been thoroughly checked.

2. There are many companies and contractors that offer a long period of warranty on pipes and fittings because of the fear of cracking and leaking, so don’t worry about it too much.

Q: How can you fix a sprinkler system?

A: A sprinkler system is yet another system that also uses and operates on water power systems. Here’s how to repair them:

1. The head must be replaced.

2. Do a clean and reset method by disassembly.

3. The spray pattern can be replaced.

4. Valves may need to be checked.

5. Repair leaks using a slip coupling.

6. Remove tree roots that might crush pipes.

7. Check the voltage of the system.

8. Check on the transformer.

9. Do a solenoid replacement.

10. Check your user’s manual for other troubleshooting problems.

Q: What is a bar?

A: A bar is a unit of measurement that centers around force. It is commonly used for force measurement and for water power and atmospheric measurements. It has the following conversions, if ever you need to convert it to another unit of measurement that centers around force:













Q: What should you look for in a water power system hose?

A: The hose is one of the most important things that should be present in a water power system for it to work properly in detecting the right force for it. Most systems already come with a hose, but here are things you need to look for on it:

1. The size should be just right.

2. The temperature should be okay.

3. It should be easy to use for application.

4. The materials should be durable.

5. It should have the right pressure.

6. Ensure that the ends are correct.

7. The delivery should work well.

Q: What are some available hose types for water power systems?

A: A water power system may have different kinds of hoses, and all varying in their MPa and PSI, such as the following:
