Useful Guide: How to Run a Pressure Washer off a Water Tank?

Pressure washing machines are used in many industries. From cleaning walls to removing hard build-ups of dirt on crossovers, these machines are essential for any business that has a large presence outdoors.

This can be a costly investment though, with gas-powered models being the most expensive of the lot.

If you are looking for a cheaper alternative to fuel-based machines, then pressure washing of a water tank may be the right choice. Running a pressure washer off a water tank is a good option for a small business.

It saves you the cost of having a water connection and paying for water and sewerage. This article looks at the How to run a pressure washer off a water tank.

Why You Need a Water Tank with Pressure Washer

It is important to make sure you have a sufficient amount of water on hand to properly operate a high-pressure water washer.

Most regular faucets and buckets don’t contain enough water to propel them at their maximum capabilities, which means they will most likely not be able to perform effectively.

If the pressure washer starts running out of water before completing its work, it will be harder for you to complete jobs in an orderly fashion.

Tanks, also known as tubs, are very useful for holding water and can be used in many different ways – including cleaning! There are many ways that water tanks can be utilized.

For example, you might like to store cooking utensils or cleaning tools such as brooms and mops as well as laundry soap and/or towels in a water storage location next to your washer and dryer.

One way you could use your tank is by using it for cleaning purposes. Another benefit of having a water storage location like this is having one for washing cars and motorcycles outside.

You can even set up a hose and water sprayer system so you don’t have to use buckets when rinsing down your car’s exterior either if you prefer.

Connecting Pressure Washer to The Water Tank

Pressure washers are meant to clean with high pressure, but if you set the pump up wrong, it will decrease the power of your washer.

So, before you start cleaning, be sure that you have the correct pressure washer pump settings.

  1. First, find the banjo fitting on the tank. Attach a threaded attachment to it. Next, attach an inline connector to the PVC pipe. Secure it with Teflon tape.
  2. Next, connect the ball valve and barb connector to your hoses. Make sure to make full use of pressure washer hoses – you don’t want any leaks!
  3. Finally, connect the hoses onto your machine; they usually fit right onto their designated place near its intake which is typically beside where garden hoses go in.

While most pressure washers may not take more than 8 minutes to assemble, we understand that they can be incredibly difficult to operate and there might be a small possibility it could blow up in your face if the component pieces aren’t connected correctly.

Running a Pressure Washer off a Water Tank

The process of running a pressure washer can be quite simple when you use the right tools.

To begin, you’ll need to make sure that your water tank is in place and close by where you intend to wash things because portability is important in order to move quickly from one stain to the next.

You could damage your pressure washer pump, hose, and filter by feeding the water into it with a thin pipe if the pipe is not properly connected.

To fix this, you need to place both your machine and the tank in such a way that the entrance of the water tank points towards your washer’s inlet pipe, so that there is no pressure loss when water flows from the tank to the pressure washer.

In order for your power washer to work properly, it is imperative that the supply lines are attached firmly to each other. They might accidentally disconnect when you’re burning through fat stacks of cash on a project.

It’s also not good when they come loose when the machine is working the way it should because if one of your nozzles comes loose and gets sucked into the engine or something, best-case scenario, you’ll have a huge mess on your hands.

Either way, reconnecting them is going to be difficult to do right in the first place! In order for these nozzles not to come loose inadvertently, tie them down securely with rope or something before turning on your gas-powered tool.

Next, turn on all of the other appliances and then turn on the main engine switch before pulling its trigger to wash away all that nasty filth from previous projects.

Get the Right Pressure

In a pressure washer, water goes from the pump inside its engine through a hose. That, in turn, generates a fine spray of water at a high speed and with a lot of force through another hose and nozzle attached to the wand.

The water has to exit the machine at a higher rate than it enters so as to keep going smoothly throughout your workday.

If there isn’t enough water flowing into the machine, then you risk damaging some of its vital components like the seals and gaskets which compromises your safety if you end up pumping high-pressure output into it without proper preparation or maintenance beforehand.

So, remember that knowing how to regulate the water supply is vital for the safe operation of your equipment and overcoming difficulties quickly.
