Can I Gravity Feed a Pressure Washer? Tips From Pros

A suitable water source is essential to using your pressure washer effectively. A faucet will usually be available for jobs around the house. But there can be many reasons why you would like to use a gravity-fed water source. I get many questions from users about whether they can use such a source or need a water pump.

Generally, you can only gravity feed a pressure washer after ensuring it delivers enough water and suitable pressure. Most budget-friendly pressure washers need around 1 gallon per minute (GPM) with a pressure of around 20 PSI. But my experience is that most machines will work fine with lower pressure. If the gravity-fed water source can not deliver enough force, a pump should be.

In this article, I will show what needs to be done to gravity-feed a pressure washer. And if the pressure from the water source is not strong enough, how can it increase? I will also look at using water from a lake, pond, or rain barrel.


Can I Gravity Feed my Pressure Washer from a water tank?

Generally, you can gravity-feed a pressure washer with gravity-fed water from a water tank. Ensure the pressure and amount of water from the tank are sufficient for your pressure washer model. If this is not the case, increase the height of the tank to increase the pressure.

Using a suction hose to get the water from a barrel, you can only use specific gas and electric models.

The output pressure (PSI) and amount of water (GPM) are essential to use water from the tank. A pressure washer needs a minimum pressure and amount of water to work well.

More budget-friendly pressure washers often need a force of around 20 PSI and 1 GTM even though my experience is that they will work fine under lower pressure.

– Use a Pressure Gauge

You can check the output pressure with a pressure gauge. If you notice that it is much lower, you have two options. One is to use a pressure washer with gravity-fed water that can work with lower pressure. Or increase the pressure from the water tank.

Pressure washers with lower input pressure are the same models that can work with a sucket hose. These are mostly gas models that have a belt-driven pump. Some more budget-friendly electric pressure washers, like the Karcher K4 and K5, also have this capability.

To increase the pressure from a gravity assist water tank, you must increase the height between the tank and the pressure washer. If the tank is portable, you can place it on higher ground. Or put it on a taller, more robust construction that can bear the tank’s weight and water.

Gravity feeding in pressure washers is a simple concept where the water supply is placed higher than the machine, allowing gravity to push water into it. It’s a cost-effective solution, especially when accessing a pressurized water source might be challenging.

Another method to increase the pressure from a water tank is to use an additional pump. You can use a regular water pump for this. It only needs to be able to deliver a specific output pressure with enough GPM.

Always ensure that your pressure washer has an inlet filter. Water from a tank will generally have more dirt than an ordinary faucet.

This dirt is harmful to the pressure washer pump. If your pressure washer does not have one, purchase a good-quality one. And mount it between the hose and the pressure washer.

Do I Need a Pump Between My Tank and My Pressure Washer? Some useful tips

You only need an additional pump between my tank and pressure washer if the current water pressure is insufficient. Most budget-friendly pressure washers need around 20PSI, but most will still work fine with somewhat lower pressure.

Adding a regular water pump will make a big difference when you notice inadequate water pressure. This is a common scenario you might encounter when you use a pump.

Another method would be to use a suction hose. Not all pressure washers have such a capability. Mostly, gas models with a belt-driven pump and more budget-friendly electric pressure washers, like the Karcher K4 and K5. With a suction hose, ensure the water level is higher than the pressure washer.

When using water from a tank, ensure your pressure washer has an inlet filter. Water from a water tank generally has more dirt and contaminants than water from an ordinary faucet. These materials are harmful to the pressure washer pump.

If your pressure washer does not have one, purchase a good-quality one. And mount it between the host and the pressure washer. Remember to set your machine and power source correctly for a wide range of hard surfaces. Always set your equipment correctly to ensure optimal performance.

How Do You Increase Water Pressure in a Gravity Fed System? Some useful tips

Generally, to increase the water pressure in a gravity-fed system, you must increase the height between the water source and the pressure washer. Use between the water source and the pressure washer short and thick hose, and minimize bends.

This will ensure a minimum pressure loss. If the pressure is still insufficient, add a portable pump between the water source and the pressure washer. This choice is a critical factor in dealing with dust and grime.

The height between the water source and the pressure washer mainly defines the pressure from a gravity-fed system. Increasing the height will increase the pressure. For a fixed installation, this will be difficult to change.

But if you have a more portable setup, it is possible to raise it. This kit often connects the pressure washer to the water source.

Understanding the Importance of Water Pressure and Volume

Besides the pressure, the amount of water is also essential. When the end of the hose has a small output diameter, the pressure will increase. But understand that your pressure washer needs a certain amount of water to work correctly. This is where the engine of the pressure washer comes into play.

If the water source can deliver a relatively high GPM, you can use a short hose with a large diameter to increase the amount of water reaching the pressure washer. This will not increase the pressure directly but ensure the pressure washer works fine. To minimize any pressure loss, reduce the number of bends.

For example, the pressure washer gun can be adjusted to share the water pressure effectively. A professional pressure washer, a pressure washer designed for heavy-duty tasks like cleaning concrete, can handle this well.

Do Pressure Washers Need a Pressurized Water Supply? Some useful tips

Most budget-friendly pressure washers need a minimum pressure of around 20 PSI to work correctly. But my experience is that most will work fine with lower pressure. Pressure washers are built to push the water with high pressure out of the nozzle, not to suck water from a water source.

Only some models with a belt-driven pump and a few electric pressure washers, like the Karcher K4 and K5, can work with a suction hose.

If the pump doesn’t get adequate water with a certain minimum pressure, the pump can be damaged. Air bubbles, called cavitation, can occur and even lead to the pump exploding.

Can a Pressure Washer Draw Water From a Lake? Some useful tips

Almost all pressure washers can not directly draw water from a lake or pond. Some people claim success, but my attempts were not successful. To try it, you need a pressure washer that can work with a suction hose.

Those are mostly gas models with a belt-driven pump and a few electric pressure washers, like the Karcher K4 and K5. Ensure the height between the suction hose and the pressure washer is as low as possible.

If your pressure washer cannot draw water from a lake, you can use a submersible or well pump. There are both electric and gas pumps. Ensure that you always use a good-quality inlet filter. Water from a lake or a pond will contain many impurities that should not reach the pump.

If your machine does not have one, add it between the hose and the pressure washer. Check and clean the filter regularly.

Can You Connect a Pressure Washer to a Rain Barrel? Some useful tips

Rain barrels are similar to other water containers, except for collecting rainwater. There are two main methods to use this water with a pressure washer. If the rain barrel has an outlet at the bottom of the barrel, you can connect a hose to it. The other method is to use a suction hose.

If you use the outlet at the bottom of the rain barrel, ensure the pressure is enough for your pressure washer. Most pressure washers need a force of around 20PSI.

But my experience is that they work fine with lower stress as well. Increase the height between the barrel and the pressure washer to increase the pressure.

– Adding a Pump for Better Pressure

If your pressure washer does not work well because of the lower pressure, add a pump between the barrel and the pressure washer. To minimize pressure loss in the hose, use a short one with a large diameter. And reduce the number of bends.

As the water in the rain barrel will contain many impurities, always use a good-quality inlet filter.

If you plan to use a suction hose, you must ensure that your pressure washer can use one. Those are mostly gas models with a belt-driven pump and a few electric pressure washers, like the Karcher K4 and K5.

The suction hose usually has a filter, so ensure your pressure washer has one. Check and clean it regularly.

One unique experience was setting up a gravity-fed system on a steep hillside. Ensuring the water tank was secure and the water flow was consistent was challenging, but we managed to make it work.

Understanding Gravity Feeding for Pressure Washers
