Water Tank Size for a Pressure Washer

by Sean

The average residential pressure washer uses around 3 gallons of water per minute. That means it will take around 20 minutes to use up the tank’s capacity of 20 gallons. A typical car wash takes anywhere from 10 minutes to 30 minutes, depending on whether you’re washing your car yourself or letting someone else do it for you. So, if you wash your car at home, and do so with a pressure washer, then it’s not going to cost much more than using conventional methods (i.e., brushes and sponges).

So, what’s the average size of water tank needed by a pressure washer? Read on for this pressure washing estimate calculator guide:

The water tank size for a pressure washer is important. It determines how long you can spray. If the pressure washer uses too little water, you’ll need to refill it too often. If it uses too much, then it will be difficult to control the spray and may cause damage to your property or others nearby.

The size of the tank also affects how powerful your pressure washer is. A larger tank will allow you to use more water at once, which makes it easier to clean large areas with one pass.

Types of Pressure Washer Tanks

Here are some different types of tanks that you can choose from:

A smaller plastic tank with a 1-gallon capacity is perfect for cleaning small areas like around your house or car without having to refill often. This type of tank is also lightweight and easy to carry around when full.

A medium-sized metal tank that holds 2 gallons should be used for cleaning medium-sized areas like driveways or decks without having to refill very often. These tanks tend to be heavier than plastic ones, but they can also hold more water at once and are less likely to leak or crack than plastic ones over time as well as being much less expensive than other options available on the market today!

How to Reduce Water Usage in Pressure Washers

It’s easy to save water when using a pressure washer. To do so, follow these tips:

  1. Use a bucket to rinse the surface instead of spraying it with water from the hose. This will help prevent puddles from forming on surfaces that don’t need cleaning and will save water!
  2. If you are cleaning cement or other hard surfaces, try using an “anti-spatter” nozzle instead of an ordinary spray nozzle. Anti-spatter nozzles have fewer holes than ordinary nozzles, which means less water is released onto the surface being cleaned each time you pull the trigger on your wand. This will save both time and money on clean-up because there won’t be as much dirt left behind after rinsing off surfaces with an anti-spatter nozzle compared to one without them!
  3. Use low-pressure settings. Some pressure washers have two settings: high and low. Use the low setting for most jobs and save yourself some money by not having to buy as much soap or detergent.
  4. Use a hose nozzle before attaching the wand. This will help you get started with less water and detergent while still providing enough pressure for cleaning purposes.
  5. Shut off your unit when not in use. Leaving your unit running while unattended can lead to wastefulness and unnecessary energy consumption, which adds up over time.


If there was one piece of advice I could give to users of pressure washers, it would be this. Know how much water your unit uses and try to ensure that you’re not using any more than necessary. Not only will it reduce the amount of waste water that ends up on the ground or in storm drains, but it will also lower your electricity bill, an added benefit for many.

So, if you are looking to save water and money while increasing your pressure washer productivity, look into pressure reducers and limiters. There is a good chance that they might just be the benefits you are looking for. Find out more about these from Giraffetools collections.
