We all know pressure washers have similar functions, uses, and advantages, but there’s no shame in asking how to release pressure and learning how a pressure washer works.
Remember, pressure washers won’t release pressure unless you initiate it yourself.
In this article, we’ll cover everything about releasing pressure, plus more.

Quick answer
If you are in a hurry, remember these things:
- First, find the unloader valve on the pressure washer
- Next, turn the pressure release valve to the proper position of release
- Finally, turn the pressure valve back to the off position once it is released
If you need to release frequently, consider investing in a gauge on the pressure release valve.
In the upcoming section, we’ll cover this more in-depth and include several visual aids.

How to release pressure from your pressure washer
Below are some simple ways and methods about how to release pressure.
1. Find the unloader valve
The unloader valve is usually near the pump. You may notice a lever or knob there that will turn.
2. Turn the valve
The importance of this step is to allow pressure to escape from the pump. It also affects the overall pressure system of the machine.
3. Once released, turn the unloader valve back to the off position
This step is to help you hold the pressure from escaping. It can also allow the remaining pressure to go into the hose so you can resume the job at a lower PSI setting.
Side note: If you need frequent release, consider investing in a gauge on the pressure valve.
A gauge will allow you to observe the pressure washer’s current pressure at a glance. These gauges can scale over 2,000 bar or 29,007 PSI.
Safety considerations
Remember the number one rule, safety first!
These machines are powerful, so to avoid pressure washing wounds, here are some safety tips:
Wear protective equipment
High PSI settings with a 0-degree nozzle can damage surfaces such as concrete (not to mention your body!) So beware!
Wear gloves, boots, safety glasses or protective goggles, and long pants to combat this while hearing protection.
Never point the wand or gun at someone
Remember that the machine has an incredible amount of pressure, so think about what it can do to an innocent bystander.
Treat pressure washers with caution because they are not a toy.
Observe your surroundings and be conscious
To ensure your safety, you need to observe the surroundings. Evaluate possible risks and be aware of obscure obstacles, hoses, debris, children, and animals.
Frequently asked questions
Below are some of the questions that many people commonly ask:
Is it Ok to idle a pressure washer?
No; without cooling the pump head, the temperature of the pressure washer will climb to 200 plus degrees.
In addition, the O-rings and water seals will soften and wear out if it gets hot. Also, valves can be distorted and warped.
Finally, cavitation might be forming because of the low pressure on the pump side that destroys some components.
What should you not do with a pressure washer?
- You should not underestimate its power
- Don’t point the nozzle and the wand at other people and pets
- Don’t bring the nozzle extremely close to the surface you’re cleaning
- Don’t use hot water
- Don’t use harsh chemicals
- Don’t let the pressure washer run too long without pulling the trigger
Conclusion
To sum it up, locate the unloader valve of the pressure washer and use this to release any unwanted pressure. Also, familiarize yourself with the items needed to operate them well to avoid wounds and injury.
We hope this user guide serves you well and you have a better understanding of how to use a pressure washer.
