How To Drain Gas From A Pressure Washer [5 Easy Steps]

If you own a gas pressure washer, you know how important it is to drain the gasoline when you’re finished using it properly.

In the springtime, when more lawns are mowed than in the fall and winter, homeowners may find themselves with a gas pressure washer that’s not being used.

Before you put the tool away for the season, it’s important to know how to drain gas from a pressure washer. This is because, if you don’t drain the gas, it can build up in the engine and cause problems.

However, it becomes much more frustrating when you notice that the gas isn’t coming out. That’s the point where we come up. We’ve compiled a comprehensive guide to make your job easier.

Why Should You Drain Gas from Your Pressure Washer?

All the various machines that we use daily foster the obligation to earn a practice of taking good care of them, or needing to repair them. The same thing goes for a gas pressure washer as well.

Here we’ve listed below why it’s critical to drain gasoline from your pressure washing machines:

To Prevent damages

Discharging gas from pressure washing machines is a way of preventing damage to your pumps.

When you drain the gas out of a pressure washer, you draw out old gas from your manufacturing washer and replace it with a new one.

To Prevent Starting Failure

Yes, this really is the case! If you don’t empty the fuel from your pressure washer, it may cause or lead to your machine not starting, and it could possibly be your fault.

To Avoid Stock Fuel 

Avoiding the stock fuels in your pressure washer means you always try to drain out the fuel from your pressure washer. This is advantageous because this means you’ll refill your pressure washer with brand-new fuel.

Not only should you avoid this occasionally, but it’s even better if you replace your current fuel with a solid one before you begin doing anything else.

To Save Time

By draining the gas, you will save time because you did not have to sit, but you may make your time productive by staying focused on what you have to do.

How To Drain Gas From A Pressure Washer?

There are several ways to drain gas from a pressure washer. However, we’re going to show the easiest method, which is using a siphon hose.

A siphon hose is a long, flexible tube made of rubber or plastic that can be easily coiled to suck up liquid or debris from a surface and then release it elsewhere. Let’s see the step by step process:

Step-1: Place the Hose Inside

If you’ve purchased an entire siphon hose kit, check out the included hose. There, one brass nozzle is fitted with one connector at the other end. You should have this end inserted into the gas tank.

When inserting the hose, it’s important to ensure that it’s at the bottom. This is because, if you don’t place the hose at the bottom, you won’t be able to drain all gas from the pressure washer.

Step-2: Clamp the Hose

Now it’s time to clamp the hose. We recommend clamping the hose to the tank’s opening. This way, the hose doesn’t move or separate from the tank.

Often, if you order a siphon kit, you’ll receive a clamp to secure the hose. You can also use duct tape or tie-wrap instead to secure the hose.

Step-3: Install the Pinch Clip

A pinch clip is used to manage the flow of a liquor or liquid by moving it from one place to another, such as draining off a specific volume. Suppose you want only a certain quantity of fluid.

Or else, you want to substitute the container halfway through this process. Pull a pint off of the pinch clip and prevent the liquid from flowing by.

Step-4: Attach the Bulb Valve

A bulb valve is a type of valve that has a cylindrical-shaped body with a round disc at one end. The disc has a hole in the center that allows fluid to flow through it. When the disc is rotated, it opens and closes the hole, controlling fluid flow.

You’ll get this valve with the kit package. Connect the bulb valve to the free opening of the hose.

Pay close attention, and you’ll see an arrow icon at the base of your water valve serving as the direction for which the water drains. Connect the hose to the end of the arrow that the arrow icon is pointing away from.

Step-5: Pump Out the Gas

Now it’s time to pump the bulb valve. Pumping the bulb valve will gradually purge all fuel from the tank. As you begin pumping, aim to always keep the gas flowing until the fuel dispenser valve reaches the point where the connector clip is pressed.

As long as the gasoline level comes to that mark, you want to put in the connector clip-in. Now, uninstall the fuel filler fill valve and pour out the gasoline into an appropriate container or wash pan.

Be sure the pressure washer is positioned higher than the container you drain the fuel into.

Gas can sit in a pressure washer for up to six months, but it’s best to use it up as soon as possible.

To clean a gas tank on a pressure washer, you will need to first remove the gas cap. Next, you will need to attach the cleaning attachment to the end of the pressure washer wand. Finally, you will need to insert the wand into the gas tank and spray the inside of the tank with water.

  • Will a gas pressure washer start without water?

It’s possible for a gas pressure washer to start without water, but it’s not recommended. The pump on a gas pressure washer relies on the water to cool it down and keep it from overheating. If the pump starts without water, it can overheat and damage the pressure washer.

That’s all there to know regarding how to drain gas from a pressure washer. We’d suggest you be super careful with the hose. It’s the prime key to a pressure washer.
