Step-by-Step Guide to Connecting a Pressure Washer Gun to a Garden Hose

1. Check the Hose and Gun Fittings

Before you start, ensure that the fittings on your garden hose and pressure washer gun are compatible. Most pressure washers use a standard 3/4-inch garden hose connector. If your hose or gun has a different fitting, you may need an adapter.

2. Turn Off the Water Supply

Make sure the water supply is turned off before connecting the hose to prevent water from spraying out unexpectedly.

3. Attach the Hose Adapter (if needed)

If your pressure washer gun requires an adapter to fit the garden hose, install the adapter first. Wrap the threads of the adapter with Teflon tape to ensure a watertight seal, then screw the adapter onto the gun securely.

4. Connect the Garden Hose to the Pressure Washer Gun

Apply Teflon Tape: Wrap Teflon tape around the threads of the garden hose connector. This helps create a tight, leak-free seal.

Screw on the Hose: Attach the garden hose to the pressure washer gun by screwing it on clockwise. Tighten the connection by hand first, then use an adjustable wrench to make it snug. Be careful not to overtighten, as this can damage the threads.

5. Check the Connection for Leaks

After connecting the hose to the gun, turn on the water supply slowly. Check for any leaks at the connection point. If you notice any water dripping, turn off the water, tighten the connection slightly, and recheck.

6. Secure the Connection

Once you’ve ensured there are no leaks, make sure the connection is secure. A loose connection can lead to reduced water pressure and inefficiency.

Tips for Maintaining a Leak-Free Connection

  • Regular Inspection: Periodically check the hose and gun connection for any signs of wear or leaks. Replace worn-out O-rings or connectors as needed.
  • Proper Storage: Store your pressure washer and hoses properly to prevent damage to the connectors. Avoid kinking or tangling the hose.
  • Use Quality Components: Invest in high-quality hoses and connectors to ensure durability and a better seal.

Troubleshooting Common Issues

Leaking Connection: If you notice persistent leaks, try adding more Teflon tape to the threads or replacing the O-rings.

Poor Water Pressure: Ensure that the hose is not kinked or blocked. Check the water supply for adequate pressure.

Incompatible Fittings: If your hose and gun fittings don’t match, purchase the correct adapter from a hardware store.


Connecting a pressure washer gun to a garden hose is a simple task that can be done in a few minutes. By following these steps and ensuring a secure, leak-free connection, you can maintain optimal performance of your pressure washer. Regular maintenance and inspection will help keep your equipment in good working order and extend its lifespan. Happy cleaning!
