The steps on how to connect pressure washer gun to garden hose are listed below:
- Determine the size of the pressure washer fitting or connector needed to connect the garden hose, washer pressure hose, and the pressure washer,
- Connect the garden hose to the high-pressure hose that is already connected to the pressure washer,
- Connect a pressure washer gun,
- Pull the pressure washer gun’s trigger,
- If there are no leaks, the cleaning process can start.
More information about is it possible to hook up a garden hose to a pressure washer, differences between a garden hose and a high-pressure hose, and how to connect a pressure washer gun to a garden hose is provided below.
Can Garden Hose Be Connected to Pressure Washer?
A garden hose can be connected to a pressure washer only if a connector or a high-pressure hose that can withstand at least 2,700 PSI is connecting the pressure washer spray cannon to the pressure washer. Connecting a garden hose directly to a pressure washer is dangerous since chemicals used for pressure washing, such as pressure washer detergents can leak into groundwater and pollute it. Connecting a garden hose directly to a pressure washer can also result in a ruptured hose and cause injuries.
Difference Between Garden Hose and High-Pressure Hose
The difference between a garden hose and a high-pressure hose is in the PSI each can withstand. Garden hoses are rated between 300 and 500 PSI while high-pressure hoses are rated at 1,000 to 6,000 PSI. To connect a pressure washer gun to a garden hose, a connector or a high-pressure washer hose is needed because using a garden hose solely can damage the pressure washer and itself.
How to Connect Pressure Washer Gun to Garden Hose
The steps on how to connect pressure washer gun to garden hose are listed below:
Use a pressure washer connector
A pressure washer connector connects the pressure washer gun and the garden hose. Pressure washer connectors are made of plastic and brass. There are quick connectors, M22, ⅜” threaded and M22 ¼” threaded connectors.
M22 connections consist of male and female connectors. To be able to connect the pressure washer gun, high-pressure hose, and garden hose, male connectors should be connected to female connectors and vice versa. An adapter can be used for converting a male into a female connection and conversely. The ⅜” connectors have female and male variants and are narrower than M22. The quick-connect connectors make connecting a garden hose to a pressure washer gun easier since they don’t use threads and are leakproof.
The type of connector should be chosen based on the GPM or gallons per minute it can withstand. The type of connector is determined by the flow rate through the pressure washer, which is calculated in GPM. Most pressure washers are rated at 3 GPM.
Connect a splitter
Using a splitter is optional for connecting a pressure washer gun to a hose. A splitter is useful if a pressure washer is used regularly since it eases unhooking the garden hose from the water supply.
Connect the garden hose to the high-pressure hose
The high-pressure hose should be connected to the pressure washer and the garden hose should be connected to the high-pressure hose. The connection should be secured so there are no leaks.
Connect the pressure washer gun
The pressure washer gun should be connected to the high-pressure hose. Using a shorter high-pressure hose provides a greater pressure output and maintains an optimal flow rate through it.
