Do you need an outside tap for a pressure washer?

Pressure washers can seem complicated, but we’re here to simplify things. We’ll address your queries and provide you with the knowledge you need. Let’s dive into the details together.

Do you need an outside tap for a pressure washer?

A pressure washer without connecting to an outside tap is possible if the water source has enough pressure to feed water to the pressure washer pump. Or if you have a pressure washer with its supply or can pump up the water from an external source. For a standard pressure washer, you can not simply place the pressure washer hose inside a water source and turn the pressure washer on.

Want to understand the flexibility of pressure washers? We’re here to guide you through the process. Learn how these machines can operate independently of an outside tap. Keep reading to uncover the details.

How to Use a Pressure Washer Without an Outside Tap?

When a pressure washer is running, it draws a significant amount of water. Some heavy-duty pressure washers use as much as 8 to 10 gallons of water per minute when running.  

So, the three main things you have to be careful about when using a pressure washer with a water source other than an outdoor tap are:

1. Enough water: The source should have enough water to feed the pressure washer pump.
2. Enough pressure: There should be enough suction or pressure to move water from the source to the pressure washer’s pump.
3. Clean water: The water you are using should be clean, and the water source shouldn’t have any particles or debris that can damage the pressure washer.

– Understanding the Basic Requirements of a Pressure Washer

If you can somehow fulfill these three requirements of the pressure washer, you shouldn’t have any problems running a pressure washer. Since an outdoor tap has water coming directly from the tank, it has enough gravity pressure to supply a decent amount of water to the pressure washer.

Simply put, a pressure washer needs water flowing into its pump to pressurize and shoot it out of the nozzle.

The pump of most pressure washers can’t actively suck water from a water source such as a bucket because the pumps used in pressure washers are not ‘transfer’ pumps.

You can risk burning your pressure washer pump if you leave the end of the pressure washer hose in a water reservoir and run the pressure washer. This can be particularly difficult when pressure washing a deck.

– The Importance of a Filter in a Water Suction Hose

Not to mention, the water you feed into the pressure washer must be clean because you can ruin your pressure washer if something gets into the pump. This is especially important when using liquid detergents or cleaners with your pressure-washing equipment.

You can buy a special water suction hose with a filter for Electric Karcher pressure washers. Check the price here. There is also a generic water suction hose with a filter. Check the price here.

These machines can be a great water source for the pressure washer you’re using without causing any excess strain on the system.

How do you pressure wash without an outside tap?

While the ideal way to use a pressure washer is by connecting it to an outdoor tap, some methods allow you to temporarily and even permanently use it without requiring an outdoor tap.

This is an excellent solution for people who don’t have an outdoor tap. You can use your pressure washer without an outside tap through the following ways:

● Using an indoor tap

The most obvious alternative to an outside tap is an indoor tap to feed water into the pressure washer. But most pressure washer hoses aren’t long enough to reach an indoor tap, so you must get a little creative to use an indoor tap for running a power washer.

Since most kitchen faucets are closer to windows, a kitchen faucet is an ideal indoor water source because you can quickly run a garden hose through the kitchen window and connect one end to the kitchen faucet and the other end to the hose of the pressure washer.

This is an excellent advantage for people who want to move the water from the indoor tap to the pressure washer.

But one thing you must ensure before connecting the pressure washer hose to the indoor tap is a sufficient flow of water being supplied from the tap.

When the distance between the indoor tap and the pressure washer is too long, you will not be able to get enough water pressure through the garden hose, and the pressure washer will not receive enough water to work correctly. 

This means you need to pay attention to the length of your hose to your pressure washer.

So before using a garden hose to connect the pressure washer to an indoor tap, run the tap with the garden hose connected to it to ensure sufficient water flows through it and the water isn’t losing pressure. You can find some suitable thicker garden hoses here.

– Note: How to connect a pressure washer to a kitchen tap

 Most indoor taps are not designed to connect a garden hose directly to them. Therefore, you must buy and attach an adapter accessory to the indoor faucet to connect a garden hose directly to the tap. This tap adapter is essential for connecting the hose to your pressure washer.

If you have a dedicated washing machine tap in your house and the pressure washer hose is long enough, you can connect it directly to the indoor washing machine tap.

Since these taps are of a similar size as outdoor taps, they have threading that allows you to connect the pressure washer hose directly to them. These are the taps that are similar to your water tap outside.

Stop the tap when you’re done using the pressure washer to prevent water wastage.

You can find indoor tab adapters here.

● Using a water barrel

Another great way to provide sufficient water to a pressure washer is to use a water barrel if you don’t have a dedicated outside tap.  

A water barrel can also collect rainwater and use the stored rainwater to run a pressure washer. Most decent-sized water barrels can hold up to 300 gallons of water, enough to run a pressure washer for half an hour.

And since water barrels have a tap near the bottom, you can easily connect the pressure washer hose to the water barrel tap and start cleaning without having to connect any extra extension hoses. Water barrels also have threaded taps, making joining the pressure washer hose easier.

One thing you have to be careful about when using stored rainwater is the debris that might be inside the water. Therefore, it is a good idea to keep a lid on the water barrel when it is not being used to prevent anything from falling into the water barrel.

You can find suitable water barrels here.

– Tip:

You can also fill the water barrel from the indoor tap using a garden hose and then use the pressure washer directly from the water barrel tap.  

● Using a bucket

A bucket is the least adequate substitute for an outside tap because it holds minimal water. But if you have to use your pressure washer for a very short time, it is possible to use a bucket. But there is a catch to using a bucket to feed water into a pressure washer.

As we mentioned above, pressure washer pumps aren’t meant to suck water, so some pressure washers have suction hoses that actively suck water into the pressure washer unit. All you have to do is place the suction end of the hose in the bucket and turn on the pressure washer.

But even if your pressure washer didn’t come with the suction hose feature, you can buy a suction hose accessory from the store and attach it to your pressure washer if you want to use it with a bucket.

Although you can use your pressure washer using a bucket, the pressure washer will use up the water from the bucket pretty fast, and you will have to refill the bucket repeatedly.

You can find some bigger water buckets here.

● Use a portable pressure washer

If you only do light-pressure washing and don’t have a heavy-duty pressure washer, you can buy a portable pressure washer with a built-in water tank.

A portable pressure washer will free you from connecting the pressure washer hose to a source because you can fill the built-in tank with water and start running the pressure washer.

The only downside of portable pressure washers is that they are meant to handle light usage and don’t have much power.

One of the more popular models is the bucket cordless SunJoe SPX6001C (check the details and price here) or the Karcher OC3 (check the details and price here).

Another portable model with a larger tank is the Koblenz HLT 370 with a 7.92-gallon tank (check the details and price here)

Conclusion:

If you plan on using the pressure washer frequently, the most sensible solution is to install an outside tap. But if you don’t pressure wash often and only use the pressure washer for short periods, you should be fine without an outside tap using the methods we have explained above.  

Do Pressure Washers Require an External Tap?

Pressure washers are versatile and powerful cleaning tools that quickly remove dirt, grime, and stains from various surfaces, such as driveways, sidewalks, siding, and decks. However, whether you need an outside tap for a pressure washer is common, and it’s worth exploring this in more detail.

• The Importance of Water Supply for Pressure Washers

Access to a clean and steady water supply is essential for the optimal functioning of a pressure washer. Water is the primary medium that combines with pressure to create the high-powered stream necessary for effective cleaning.

Without an adequate water supply, the pressure washer will not be able to generate the required pressure, which could lead to poor cleaning results or even damage to the pressure washer itself.

Most pressure washer manufacturers recommend a specific minimum water flow rate for their products, generally measured in gallons per minute (GPM). Ensuring the available water supply meets or exceeds this requirement for the pressure washer to operate optimally is crucial.

• Connecting a Pressure Washer to an Outside Tap

An outside tap, also known as a garden tap or hose bib, provides easy access to a water supply and is the most convenient way to connect a pressure washer. With an outdoor faucet, you can easily connect a garden hose to it, leading to the pressure washer’s inlet, and start your cleaning tasks.

Here are some advantages of using an outdoor tap for your pressure washer:

1. Ease of use: Connecting your pressure washer to an outside tap is more straightforward than other alternatives. Most pressure washers have a standard connection system that allows you to attach a garden hose quickly.
2. Steady water supply: Outdoor taps are usually directly connected to the main water supply, ensuring ample water flow to meet the pressure washer’s requirements.
3. Better cleaning performance: Connecting a pressure washer to an outside tap allows you to clean various outdoor surfaces for an extended duration without worrying about refilling a water source.

– Recommendations for Outside Tap Use

Based on personal experience, here are some recommendations for using an outside tap with a pressure washer:

• Before connecting your pressure washer, ensure the outside tap is in good working condition, without leaks or damage.
• Ensure that the garden hose you use is long enough to reach the area you intend to clean and is free of any kinks or damage.
• For optimal results, use a hose with a diameter of at least 5/8 inches, as it provides better water flow than narrower hoses.
• Always turn off the pressure washer and release the pressure before disconnecting the hose from the outside tap to avoid water hammer or other potential damage.

• Alternative Options if an Outside Tap is Unavailable

If you don’t have access to an outdoor faucet, there are a few alternative methods to supply water to your pressure washer. However, remember that some of these methods may not provide as consistent a water flow as an outside tap.

1. Indoor tap connection: Though not ideal, you can connect your pressure washer to an indoor tap using a suitable adapter. This method can be cumbersome as you’ll need to route the hose through windows or doors, and there may be potential water flow limitations.
2. Water barrel or tank: Some pressure washers can draw water from a water barrel, tank, or pond, provided the water level exceeds the pressure washer’s inlet. However, this method may require additional accessories, such as a suction hose and filter.
3. Portable water tanks: Some pressure washers integrate with portable water tanks, providing flexibility in water supply when an outside tap is unavailable. These tanks must be refilled periodically, which could be time-consuming and less efficient than a direct connection.

To learn more about alternative water sources for pressure washers, you can visit reliable resources such as the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy for expert advice and guidance.

• Remarks

In summary, while an outside tap is the most convenient and efficient way to connect a pressure washer, alternative water supply options are available if an outside tap isn’t feasible.

It is essential to understand the water flow requirements of your specific pressure washer model and ensure that the water source you choose can provide an adequate water supply to achieve the best cleaning results.

Pressure Washer Options without Taps: Are There Any?

Pressure washers are essential for cleaning various surfaces, such as driveways, sidewalks, and vehicles. They release water jets at high pressure to remove dirt, grime, and stains. Typically, pressure washers are connected to a tap to provide a continuous water supply.

But what if you need to use a pressure washer in a location where a tap is not available, or you want a more portable option? The good news is that pressure washers are available that do not require a tap connection.

This article will discuss these pressure washers and their features and provide recommendations based on personal experience.

• Portable Pressure Washers

Portable pressure washers, or self-contained pressure washers, do not require a tap connection as they come with a water tank or reservoir. This feature allows you to carry water, ideal for situations without direct access to a water source.

Some portable pressure washers can even draw water from alternative sources, such as lakes or rivers. These models are available in both electric and gas-powered versions.

– Cordless Electric Pressure Washers

Cordless electric pressure washers run on rechargeable batteries and are eco-friendly for those seeking a tapless pressure washer. With advancements in battery technology, these pressure washers can provide enough power for light to medium cleaning tasks without needing a power outlet.

Additionally, they produce minimal noise and do not generate exhaust emissions, which benefits the environment.

High-quality cordless electric pressure washers usually offer a battery runtime of up to one hour on a single charge. I recommend looking for models with Lithium-ion batteries, as they typically have a longer lifespan and maintain consistent power output throughout their charge.

A valuable resource for more information on battery-powered pressure washers is the Department of Energys guide on battery technologies.

– Gas-Powered Pressure Washers

Gas-powered pressure washers offer more power than their cordless electric counterparts, making them suitable for heavy-duty cleaning tasks. They come with a separate gas and water tank, allowing users to work independently of electricity and water sources.

While gas models produce more noise and emissions, their increased power can make quick work of more challenging cleaning jobs.

I recommend choosing a gas-powered pressure washer with a 4-stroke engine, which is more fuel-efficient and produces less emissions than 2-stroke engines. Another thing to consider is the water tank capacity – a larger tank will reduce the frequency of refills, allowing you to work more efficiently.

• Siphon-Fed Pressure Washers

Siphon-fed pressure washers are unique in drawing water from alternative sources, such as buckets, ponds, and lakes. A special siphon hose, often included with the pressure washer, is used to draw water, which is then pressurized by the washer’s pump.

This type of pressure washer is beneficial for those who need a water source away from a traditional tap, such as boat owners or campers.

When using a siphon-fed pressure washer, it is essential to ensure that the water source is clean and free from debris to prevent damage to the pump. Additionally, some models may require a separate power source, such as a portable generator, to function.

I recommend choosing a model with a quick-connect siphon hose for easy setup and a filter to protect the pump from particles in the water.

• Remarks

In conclusion, various pressure washers that don’t require a tap connection are available. Portable pressure washers, which include cordless electric and gas-powered models, come with water tanks or reservoirs.

Meanwhile, siphon-fed pressure washers can draw water from alternative sources. Deciding on the right pressure washer for your needs will depend on factors such as the type of cleaning tasks you need to perform, your preferred power source, and the availability of water sources.

Researching and comparing different models is essential to make an informed decision. Whether you need a tapless pressure washer for remote cleaning tasks or value the added portability, these alternatives to traditional pressure washers offer a viable solution.

Connecting Pressure Washers to Indoor Faucets: Is It Possible?

• Understanding Pressure Washers

Pressure washers are a popular and efficient tool to clean various surfaces, like driveways, walkways, cars, and outdoor furniture. They use the power of water pressure to remove dirt, grease, and grime from different surfaces.

However, you might wonder if using a pressure washer indoors by connecting it to an indoor tap is possible.

The short answer is yes, you can attach a pressure washer to an indoor tap, but some important factors must be considered to ensure safe and effective use.

– The Importance of Water Supply and Pressure

Pressure washers rely on a strong and consistent water supply to operate efficiently. Most outdoor garden hose connections have a higher water flow rate and pressure than indoor taps in kitchens or bathrooms.

While connecting a pressure washer to an indoor tap might work, the reduced flow rate and water pressure can affect the washer’s performance and potentially damage the unit or your indoor plumbing.

– Choose the Right Pressure Washer

Not all pressure washers are created equal. Some models are designed for heavy-duty outdoor projects, while others are more suitable for light or medium-duty cleaning tasks.

When considering attaching a pressure washer to an indoor tap, choosing a unit with the appropriate pressure and flow rate that won’t potentially damage your indoor plumbing is essential.

The most common types of pressure washers are gas-powered and electric. Gas-powered pressure washers typically have higher water pressure levels and are best suited for heavy-duty outdoor tasks.

On the other hand, electric pressure washers usually have lower pressure levels, making them a more suitable option for indoor usage.

– Universal Tap Connector

One of the challenges of attaching a pressure washer to an indoor tap is that the connections might not be compatible. To overcome this obstacle, you can use a universal tap connector, which attaches to your indoor tap and adapts it with a standard garden hose, making it compatible with your pressure washer.

These connectors are available in various styles and materials, such as plastic or metal, and are designed to fit most kitchen, bathroom, and laundry room faucets.

They can be found in most home improvement stores or online, and this article from Michigan State University Extension provides more information on connection options for non-threaded spigots.

– Safety Precautions

As with any cleaning tool, using a pressure washer indoors requires essential safety precautions to prevent any injury or damage to your home.

1. Water Distribution: Be aware of the water distribution when using a pressure washer indoors. If not adequately managed, pressure washing can create considerable water, damaging floors or electrical outlets. You can prevent potential water damage by using absorbent mats or towels and directing the water flow away from sensitive areas.
2. Ventilation: Adequate ventilation is crucial when using a pressure washer indoors. The airborne particles released during pressure washing can be harmful to breathe in, particularly in enclosed spaces—open windows and doors to allow fresh air to circulate and disperse any airborne contaminants.
3. Protective Gear: As with any cleaning task, it’s essential to wear appropriate protective gear to protect your eyes, skin, and clothing from any debris or chemicals.
4. Careful Use: Avoid high pressure on delicate surfaces, as it can damage them. Start with a low-pressure setting and gradually increase as needed.

• Additional Considerations for Indoor Pressure Washing

While it’s possible to attach a pressure washer to an indoor tap, there are additional factors to consider.

1. Noise: Pressure washers, particularly gas-powered models, can be loud. Be aware of the noise level and consider using an electric pressure washer for indoor tasks to minimize the disturbance to your household or neighbors.
2. Power Source and Cords: Electric pressure washers require a power source, which can be inconvenient if there isn’t an easily accessible outlet near the indoor faucet. Additionally, be conscious of the cords and hoses to prevent trips or falls.
3. Cleaning Solutions: Some pressure washers can use a detergent to help remove dirt and grime. When using a cleaning solution, it’s essential to choose a product appropriate for indoor use and ensure that you thoroughly rinse the cleaned surfaces to prevent any residue.

In conclusion, attaching a pressure washer to an indoor tap is possible, but it requires careful consideration of the washer’s pressure and flow rate, using a universal tap connector, and following essential safety precautions.

Proper planning and care allow you to use a pressure washer efficiently and effectively for indoor cleaning.

Bucket of Water for Pressure Washing: Can It Work?

Pressure washers are powerful cleaning tools that use water at high pressure to remove dirt, grime, and stains from surfaces like concrete, wood, and cars. Often, pressure washers are hooked up to a water source like a garden hose for a steady water supply.

However, what if you don’t have access to a garden hose or a faucet? Can you use a pressure washer with a bucket of water instead? The answer is yes, but there are some important considerations to remember.

• How Pressure Washers Work with a Bucket of Water

Pressure washers typically use a pump to increase the pressure of the water that passes through the hose and exits through a spray gun or nozzle. When using a bucket of water, the pressure washer’s pump will draw water from the bucket, pressurize it, and then expel it through the nozzle.

You will need a self-priming pump designed to draw water from a static source, such as a bucket or a tank, to use a pressure washer with a bucket of water. Many pressure washer models already come with a self-priming pump, but you should check the specifications of your particular model.

– The Role of the Self-Priming Pump in Pressure Washers

If you’re unsure whether your pressure washer has a self-priming pump, consult the user manual or the manufacturer for more information.

Ensuring the bucket you use has sufficient water capacity for your cleaning task is essential. Remember that pressure washers consume large volumes of water quickly; for example, a pressure washer with a flow rate of 2 gallons per minute (GPM) will drink 120 gallons of water in an hour!

Consider the flow rate of your pressure washer when estimating how much water you will need for your project.

• Setting Up a Pressure Washer with a Bucket of Water

To set up a pressure washer with a bucket of water, follow these steps:

1. Place the pressure washer near the bucket or water source.
2. Make sure the pressure washer is off and disconnected from any power source.
3. Fill the bucket with clean water.
4. Attach a water filter or strainer to the inlet hose of the pressure washer. This will prevent dirt and debris from the bucket from being drawn into the pressure washer and damaging the pump. You can find water filters and strainers at most hardware stores or online.
5. Submerge the inlet hose with the water filter or strainer in the bucket of water. Please ensure the hose is at the bottom of the bucket to ensure it draws water efficiently.
6. Please turn on the pressure washer and wait for it to prime. Depending on the model, this process may take a few seconds to a minute or more.
7. Your pressure washer is ready once you see a steady flow of water from the nozzle or spray gun.

Remember to monitor your water bucket level frequently to ensure sufficient water for the pressure washer. If the water level becomes too low, the pump may start to draw air, which can cause cavitation or other damage to the pump.

• Advantages of Using a Bucket of Water with a Pressure Washer

There are several benefits of using a bucket of water with a pressure washer, especially when a water source like a garden hose or faucet is unavailable. These advantages include:

• Portability: When working in remote areas or places without accessible outdoor water sources, using a bucket of water allows you to complete your cleaning tasks effectively.
• Water Conservation: When water conservation is a priority, using a bucket can help you better control and monitor the water you use during your project.
• Using Different Water Sources: If your cleaning requires particular types of water, such as distilled water or collected rainwater, using a bucket allows you to utilize those water sources.

• Remarks

Using a pressure washer with a bucket of water is an effective and practical solution for situations where a traditional water source like a garden hose or faucet is unavailable. To ensure a successful cleaning project, ensure your pressure washer has a self-priming pump and is appropriately set up with a water filter or strainer.

Continuously monitor the water level in your bucket to avoid potentially damaging your pressure washer’s pump.

For those looking for more information about pressure washers, the Pressure Washing Resource provided by the Cleaning Equipment Trade Association contains articles, guides, and tips.

With proper setup and precautions, a bucket of water can effectively serve as a water source for your pressure washer, allowing you to tackle a wide range of cleaning projects quickly and efficiently.

Question	Can you use a pressure washer with a bucket of water?
Answer	Yes, you can use a pressure washer with a bucket of water, but it requires a pressure washer designed for sucking water from a separate container. Make sure to check if your pressure washer supports this function before using it with a bucket of water.
