How to Connect Pressure Washer to Water Tank?

If you want to preserve the exterior of your home and swiftly clean vast areas, pressure washers are useful pieces of equipment to have. How to connect pressure washer to water tank is one of several issues that need to be addressed.

Selecting the best pressure washer can be challenging because there are so many different kinds on the market. Choose the option that precisely satisfies your property requirements. Thus, I’ve written a guide on how to connect a pressure washer to a water tank.

What Is a Pressure Washer?

A pressure washer is a tool that increases the water pressure from a home water faucet to more than 1,000 PSI, allowing the user to use the pressure difference in combination with an optional surface cleaner to remove undesired filth and grime from a range of things. Washers that produce electricity or power are available.

Electric power washers are smaller, lighter, and easier to transport than gas power washers. However, they lack the same power as gas pressure washers, which requires more caution. Power washers powered by electricity can be used both inside and outside. Gas power washers, however, are exclusively employed outside. You might be able to quickly remove sizable areas of hard exterior surfaces with the aid of a pressure washer.

A pressure washer can be used to clean nearby concrete, such as a terrace, sidewalk, or road, as well as wood subfloors, paneling, cars, and other objects made of the material. They are perfect for situations where using brushes and soapy solutions would normally take an age. Pressure washing is also advantageous since it gets rid of impurities that are hard to get rid of, including grease, tar, glue, varnish, or even iron.

Why Do You Need A Water Tank With Pressure Washer?

Many believe pressure washers use more water than standard garden hoses because they shoot water at such a high rate. It’s all a scam! According to research, a high-pressure washer can use up to 20 gallons of water every minute, but a garden hose can only use about 8 gallons.

So why do we have a tank if a pressure washer doesn’t use much water? In reality, is it possible to operate a pressure washer off of a water tank?

The reply is that you are not required. However, you must if you want to securely and conveniently clean any surface.

You risk damaging the pump’s gaskets, seals, and other parts if you start the engine without putting water through its system. Thanks to the water tank, you can have continuous water flow via the pressure washer.

Benefits of Pressure Washer Use with a Water Tank

Greater output

You will produce more if you have a water tank. A water tank will produce almost twice as much output as a conventional garden hose, depending on the pressure washer you buy. This added strength can be used to remove stubborn dirt and stains from concrete, tile, and even wood.

No water connection is required

There isn’t a connection to a standard water supply, so you won’t have to worry about lugging your hose around as you move around. You may clean anything as long as your tank has enough pressure.

Go green

Using a water tank with a pressure washer is an efficient technique to preserve water while cleaning for individuals who have intentionally chosen to live sustainably. Water tanks don’t need to be near a source of running water all the time. It doesn’t lose hundreds of gallons of water every minute while using it if it is not linked to the mains. This is excellent news for the environment and your wallet if you’re trying to go green and save money on your water bills.

How To Connect Pressure Washer To The Water Tank

To get the right water pressure, it is crucial that you set up your pressure washer correctly to get the right water pressure out of the pump.

How to hook up a water tank to a pressure washer step-by-step:

Find the banjo fitting on the tank first. A thread must be connected to the fitting. Afterward, join an inline to the PVC. Use Teflon tape to affix it. The ball valve and barb connector should then be connected. The hose can now be attached.

You can get a barb connector from the store if the hose is missing one. However, for the water to stay in the hose and not leak out, the barb must be tightly secured.

The hose can now be attached to the feed pipe for the pressure washer. Its inlet is typically located next to the garden hose’s intake.

You can connect the pressure washer to the water tank in less than 10 minutes. Furthermore, you may do the task with little to no help because fittings, valves, and tubes can easily connect to one another.

Note: Check for leakage

Remember to check for leaks in the tank and its connections. Listen for dripping or feel the area near any connection for moisture. You might have a leak at a plug or valve if you see water trickling down the tank’s side.

How To Run A Pressure Washer Off A Water Tank

Can I still use a pressure washer that isn’t driven by electricity with a water tank?

Operating a pressure washer off a water tank is the same whether it is driven by a gas engine or an electric motor. It activates a pump that forces water out of the spray wand under pressure. It’s crucial to utilize the right spray nozzle.

The many spray nozzle types are as follows:

  • Spray nozzle for detergent: for thorough cleaning
  • Nozzle for flushing: for routine cleaning
  • Using a blasting nozzle to remove tough spots

You can start using the pressure washer off the water tank as soon as you attach the appropriate spray nozzle to the hose.

For about a minute, run the water. This is necessary to purge the system of air and prime it. To release water pressure, squeeze the trigger on the spray nozzle. To start the engine, pull the starter cord one last time.


You know how to connect a water tank to a pressure washer. It is simple to accomplish on your own. First, you must understand how to join the pipes to the equipment and taps. To get the most out of the washer, ensure your water sources offer a steady and continuous flow. Before using the washer with the faucet cranked up, release the air and prepare it.
