Connecting a hose to a pressure washer is an important step to get right in order to have a properly functioning system. There are a few key things to keep in mind when connecting the hose that will ensure a tight seal and prevent leaks or other issues. In this guide, we will walk through the complete process step-by-step to connect a hose to a pressure washer correctly.
Step 1: Assemble The Necessary Materials
Before getting started, you’ll want to make sure you have all of the right materials on hand. Here’s what you’ll need:
- Pressure washer
- Garden hose
- Hose connectors and fittings (typically come with the pressure washer)
- Teflon tape
- Adjustable wrench
It’s a good idea to have your pressure washer’s manual handy for reference as well, as connection instructions can vary slightly by model. Make sure the hose you’ll be using is reinforced and rated for high pressure. Standard lightweight hoses can burst under the pressure.
Step 2: Inspect The Connectors
Take a close look at the water inlet on your pressure washer as well as the ends of your hose and any connectors that came with your pressure washer. Check for any dirt, debris or defects on the threads. Using a rag, wipe any dirt away and make sure the threads are in good shape. Damaged threads can prevent establishing a tight seal.
Also check to make sure you have the right type of connector ends to match up with the pressure washer inlet. Most pressure washers use standard garden hose fittings, either quick-connect or threaded connections. Make sure your hose has the mating end piece. Having the correct connecting ends is crucial for linking up the hose and pressure washer properly.
Step 3: Apply Teflon Tape
To help create a watertight seal and prevent leaks, wrap the threaded ends of the hose and connectors with 2-3 layers of Teflon tape. Make sure to wrap the tape in the direction the connector will thread onto the pump. Wrapping it backwards can actually unwind the tape when tightening.
The tape fills in small gaps in the threads to block water. Take your time applying the tape smoothly and evenly. Rushed jobs can leave gaps for leaks. Be thorough covering all the threads but don’t allow any excess tape to hang off.
Step 4: Connect Garden Hose To Water Supply
With the ends prepped, you can start connecting up the components. First, attach your garden hose to the water supply you’ll be using. This is often an exterior hose bib or spigot. Make sure the connection is tight.
For longevity, consider using a rubber washer inside the connection. Washer provides a cushion and tight seal. Make sure the water supply is turned on once the hose is connected. This pressurizes the hose for the next step.
Step 5: Attach Hose To Pressure Washer Inlet
Now you’re ready to join the hose to the pressure washer. Identify the water inlet on your pressure washer. It will be marked and/or colored blue. Then take the other end of your hose and firmly hand thread it onto the pressure washer inlet.
If using a quick-connect fitting, just push the hose end into the inlet until it clicks and locks. For a threaded fitting, tighten down using an adjustable wrench once threaded by hand. Don’t over tighten, just go until sealed. Remember the Teflon tape helps get a tight seal without having to really crank down.
Step 6: Turn On Water Supply And Check For Leaks
With everything hooked up, slowly turn on the water supply to start pressurizing the system. Give it a minute or two to build up pressure, then check carefully for any leaks at the hose-pressure washer connection point. Small drips or wetness indicate a leak that needs to be fixed.
If there is a leak, turn off the water supply and disconnect the hose. Re-wrap with fresh Teflon tape and re-connect, tightening a bit more. Turn the water back on and check again. Repeat until leak is stopped. The tape helps get a perfect seal.
Step 7: Disconnect When Done Using
When you’ve finished pressure washing, make sure to disconnect the garden hose from the inlet on the unit. Never leave a hose connected when storing the pressure washer. Residual water can freeze, expand, and crack components in cold weather.
Also release any remaining water pressure by squeezing the trigger on the spray nozzle until water stops flowing. This depressurizes the system so hose disconnects easily. Draining it also helps prevent internal corrosion issues from leftover water.
Tips For Connecting A Hose To Pressure Washer
- Only use a reinforced high-pressure hose, never a lightweight standard hose
- Check condition of o-rings – cracked or worn o-rings will cause leaks
- Use quick-connect fittings for fastest, tool-free hose hookups
- Install an in-line shutoff valve to easily turn water supply on and off
- Use plumber’s tape on threaded fittings to get a watertight seal
- Ensure the water supply is off when connecting to avoid pressure buildup
- Connect to water supply before attaching hose to pressure washer inlet
- Don’t overtighten connections – snug is tight enough with help of Teflon tape
- Always disconnect and drain the hose & system when not in use to prevent damage
Following these tips and the steps outlined above will ensure you have a solid, leak-free connection between your garden hose and pressure washer. Taking the time to hook everything up correctly will mean you can get right to pressure washing without having to deal with pesky leaks or hose issues. Be sure to double check for leaks and tightness of all connections before use. Enjoy your pressure washing!
FAQs About Connecting A Hose To A Pressure Washer
What type of hose should I use with my pressure washer?
You should always use a high-pressure reinforced hose rated for at least 3000 psi. Standard lightweight garden hoses can burst under pressure washer pressure.
My pressure washer didn’t come with a hose. Where can I buy one?
You can purchase high-pressure hoses from hardware stores, home improvement centers, online retailers, or directly from pressure washer manufacturers. Look for 3000+ psi rating.
Do I need to use Teflon tape on hose connections?
Teflon tape is highly recommended to help make a water tight seal on threaded connections. It fills in small gaps in the threads. Make sure to wrap in the direction of tightening.
How tight should the hose connections be?
Connections should be tightened securely but over-tightening can cause damage. Tighten by hand first then an additional 1/4 turn with a wrench provides a snug, leak-free seal.
What do I do if my hose connection leaks even after taping and tightening?
If it still leaks, disconnect and re-tape with fresh tape. Too little tape or worn/damaged threads can prevent a good seal. Also inspect o-rings for wear and replace if cracked.
Can I leave the hose connected to the pressure washer when storing it?
It’s best to always disconnect it. Remaining water can freeze, expand, and crack components in cold weather. Also helps prevent interior corrosion.
How do I disconnect the hose from the pressure washer?
Squeeze the trigger on the nozzle to release system pressure. Then disengage the quick connect fitting or unthread the connection. Drain any remaining water before storing.
Connecting a hose to a pressure washer properly is easy to do once you know the steps. Be sure to use a reinforced high-pressure hose and fittings designed for pressure washers. Carefully inspect and clean any threaded connections. Apply Teflon tape to create a watertight seal that prevents damaging leaks. With a snug, leak-free connection, you can use your pressure washer confidently on all your cleaning projects. Remember to relieve system pressure and disconnect the hose after each use.
