How To Connect Pressure Washer To Water Tank

A pressure washer is a machine that turns the regular supply hose pressure to more than 1000 psi, which requires a lot of water. Many people think the pressure washer requires a huge amount of water, but according to authentic data, a garden hose has a higher flow rate than a regular pressure washer.

However, you must provide your pressure washer with an adequate water supply; otherwise, it might get damaged. There are two pressure washers, and the electric pressure washer is more compact, portable, and uses less water than gas-powered pressure washers. You must consider your pressure washer’s water requirement and ensure that your garden hose can provide that. In this article, we will discuss properly connecting the pressure washer to the water tank, so you do not face any problems. Let’s get started.

Connecting The Pressure Washer To Water Tank

You will need certain items to connect your pressure washer to the water tank without any problem. You will need a garden hose, ball valve, barbed connector, Teflon tape, a piece of PVC pipe, and a pressure washer. The connection process is very easy, and you can do it in minimum time without assistance. These are the steps of doing it:

  • Locate the banjo fitting on the water tank and connect the thread to the fitting. It will serve as the initial connection of your pressure washer.
  • Now, wrap the Teflon tape on the PVC pipe to make it leakproof and connect it to the inline of the connection.
  • You will now need to connect the barb connector and ball valve to the PVC pipe. Make sure that all the connections are secure and tighten them if necessary.
  • You can now attach the hose to the barb connector and secure it with a clamp or jubilee clip.

The process is very easy and will take less than 10 minutes if you do it for the first time.

Make Sure That The Connection Is Secure

The only way to ensure the connection is secure is to run the water through it. Turn on the supply and examine any minor leakage. The joints are more prone to leakage, so check them properly.

The next step is to connect the pressure washer to the garden hose. Follow all the recommended steps the manufacturer provides to ensure that all the connections are secure. Run the water through a pressure washer without turning it on and press the pressure trigger to let it run out. If the water comes from the nozzle without any problem, there is nothing to worry about. Check the water path from a garden hose to the pressure washer pump to the high-pressure hose to spray the wand and, finally, the nozzle. Make sure that no water drop comes from the unwanted spot.

Once you have tested the pressure washer, you are clear about using it.

Prepare The Pressure Washer

The true confirmation of whether you make the connection secure or not is by using the pressure washer. Prepare your pressure washer to run it. Make sure that you have connected all the connections at their designated spot. If you are using a gas-powered pressure washer, make sure you have an appropriate amount of oil and fuel in the pressure washer. Using an electric pressure washer ensures the power cord is completely secure.

Run The Pressure Washer

The next step is to run the pressure washer to check for any leakage. Some minor spots are easy to miss when the pressure is low, but when you turn on the pressure washer, you can easily spot them. Make sure that the pressure washer is perfectly safe to use. Turn the water supply on and start the pressure washer.

Spray the pressure washer with the wide-angle nozzle and confirm that it works perfectly. Check for any leakage and make sure that all the hoses, especially the high-pressure hose, are without any damage.

Things To Consider When Using Pressure Washer

If you are using the pressure washer for the first time, then there are several things that you need to consider. First, ensure that your water tank can supply the water the pressure washer requires. If the official requirement of your pressure washer is 2 GPM, then your water tank should be able to supply more.

You can check it easily by turning the hose and checking the water volume in one minute. Also, ensure that there are no air bubbles in the flowing water coming from the water tank. Otherwise, it can create huge problems in the pressure washer pump.

You should wear the proper safety equipment before using the pressure washer. Wear long pants and full-sleeved shirts and also wear safety goggles and gloves. Please do not use the pressure washer in any unwanted situation; always check it on a minor area of the surface you wish to clean. Always sweep the area with the vacuum cleaner or brush to eliminate particles that can turn into projectiles from water pressure.

Also, remove any pots, plants, or other items from the area to clear the space and save them from unwanted damage. It is important to understand that the pressure washer stream can easily puncture the skin, so keep it away from pets or children.


This article discusses the proper way to connect the pressure washer to the water tank. You do not require expert assistance; it is only a minor job. You will need a garden hose, ball valve, barbed connector, Teflon tape, and a piece of PVC pipe. Attach the thread to the banjo fitting located on the water tank. Wrap the Teflon tape around the PVC pipe and attach it to the inline connector. Connect the PVC pipe to the barb connection and ball valve. After attaching the pressure washer, run the water from the connection to check for leaks. After that, you may use it with a pressure washer, but ensure to thoroughly inspect all valves and joints because high pressure might cause them to break apart.
