There’s no specific or specially designed hose for a pressure washer. You must buy a perfect size according to the type of task and the pressure washer’s model. The perfect size hose can enhance the efficiency of a pressure washer for watering or cleaning tasks.

For instance, a pressure washer’s hose that is too small will not be able to pump out enough water to wash or water a surface. Again, a very long hose can decrease the water pressure required for a cleaning task. 

Different Types of Garden Hoses for Pressure Washers

Things To Consider While Buying Garden Hose For Pressure Washer

Before selecting a suitable garden hose for pressure, you must know the important factors that will give you the right choice! Therefore, I’ve listed some factors with practical examples to understand how they affect the pressure washer’s efficiency.

  1. Diameter

Diameter is an important factor you need to consider while choosing a pressure washer hose. As the diameter plays a vital role in the water flow rate. 

A pressure washer needs a higher flow rate to clean dirt, and dust off a surface. A strong water flow is required for larger cleaning tasks and a medium water flow is required for daily cleaning tasks, watering the garden. 

Tips: The most suitable diameter for a pressure washer is ¾” or ⅝”. These two garden hoses require higher water flow.

  1. Length

Length is another factor you must be aware of! Although there is a 20-100 feet length available for each hose size. But, you should choose according to your task.

Like, a shorter length is good for heavy-duty tasks. As the water flow is decreased with the larger garden hose. And, the larger hose causes a pressure loss!

Tips: The length of the garden hose should be between 25-50 feet. As a result, you’ll get an adequate water supply and it’ll prevent pressure loss.

3. Material

There’s a variety of materials used for designing garden hoses. Always choose a garden hose with high-quality and durable material! It will ensure that the pressure washer has an adequate supply of water without leaking or breaking! 

Some of the common materials are briefly discussed with their pros and cons below-

  • Vinyl– Garden hoses with vinyl material are more commonly used. They are very lightweight and affordable, which is the perfect choice for light-duty tasks. You can use it for watering small gardens or balconies. 

But, one thing to assure you is that this garden hose will not provide long-term durability and flexibility! 

  • Rubber: A garden hose made with rubber is great for durability. They have resistance to abrasion and kinking, which is perfect for long-term durability. It is lightweight and can be used for heavy-duty tasks.
  • PolyurethanesPolyurethane or PVC garden hoses are more lightweight, flexible and durable. They have a premium quality that can resist UV damage, kinking and abrasion. They are suitable for any heavy-duty task.

4. Connectors and fittings

The garden hose connection should be high quality and secure fit to prevent any leakage. Aluminum and plastic material aren’t better for perfect fit and connection.  You can choose heavy-duty brass fitting hose which has better resistance to corroding or leakage! 

Most pressure washers have a connection of ¾ inch Garden hose thread. However, make sure that the hose connection is compatible with the pressure washer’s inlet fittings.

5. Intended use

The purpose of using a pressure washer is another crucial factor you need to consider. 

If you need a hose for daily watering and cleaning tasks ⅝” is the best choice overall. Again, you can choose 1 ¼” hose for the commercial task and residential task.
