How To Winterize A Simpson Pressure Washer

Alright folks, gather 'round! Let's talk about something near and dear to my heart... well, maybe not near and dear, but definitely something I don't want exploding in my garage come springtime: winterizing your Simpson pressure washer. Because let's face it, nobody wants a surprise ice sculpture where their trusty cleaning machine used to be.

Think of your pressure washer like a grumpy bear getting ready for hibernation. It needs a little TLC before the deep freeze sets in, or else it's gonna wake up in the spring with a serious case of the 'I can't spray anything because I'm full of ice' blues. Trust me, a frozen pressure washer is about as useful as a chocolate teapot.

Why Bother Winterizing Anyway? (Besides Avoiding Exploding Machines)

Okay, so the exploding machine thing is pretty compelling, but there are other reasons to take this seriously. Imagine water lurking inside the pump and hoses. As it freezes, it expands. That expansion can crack the pump housing (which is like the engine of your pressure washer), burst hoses (resulting in a soggy, useless mess), and generally wreak havoc on all the delicate internal bits. Basically, it turns your pride and joy into a very expensive paperweight.

Fun fact: Water expands by about 9% when it freezes. That might not seem like much, but try squeezing an extra 9% of water into your already full water bottle. See? Pressure! And that's the kind of pressure that can ruin your day (and your pressure washer).

The Winterizing Process: It's Easier Than You Think (Probably)

Alright, let's get down to brass tacks. Winterizing your pressure washer is surprisingly simple. It's not rocket science, although if you accidentally use jet fuel instead of antifreeze, that might get you closer to rocket science than you intended. But seriously, follow these steps, and you'll be golden.

Step 1: Read the Manual! (Seriously, Do It)

I know, I know. Reading manuals is about as exciting as watching paint dry. But your pressure washer's manual is like a secret treasure map to winterizing success. It'll have specific instructions for your model, which might be slightly different than what I'm telling you here. Consider it your pressure washer's holy scripture.

Pro tip: If you've lost the manual (which, let's be honest, is highly likely), you can usually find it online. Just Google "[Your Pressure Washer Model Number] Manual." The internet is a wonderful place, full of cat videos and pressure washer instructions.

Step 2: Disconnect Everything! (Be Dramatic About It)

Unplug the power cord (safety first, kids!), disconnect the water hose (give it a good shake, like you're saying goodbye to a long-lost friend), and remove the spray wand and any attachments. Treat it like a ceremonial separation. Dramatic sighs are optional, but encouraged.

Step 3: Flush Out the Water (Get Rid of Those Pesky H2Os)

Now, start the engine and let it run for a minute or two. This will help force out any remaining water from the pump. Important: Don't run it for too long without a water source, or you'll risk damaging the pump. It's like making popcorn without the kernels – a recipe for disaster.

If your pressure washer has a detergent tank, flush that out too with clean water. Nobody wants soapy surprises in the spring!

Step 4: Antifreeze Time! (The Good Stuff)

This is where the magic happens. You'll need to introduce some non-toxic RV antifreeze into the system. Do NOT use regular automotive antifreeze! That stuff is nasty and can damage your pressure washer (and potentially harm the environment). RV antifreeze is designed for potable water systems, so it's much safer.

There are a couple of ways to do this:

• The Gravity Feed Method: Disconnect the high-pressure hose from the pump outlet. Then, attach a short piece of hose to the inlet where you connected the water hose. Place the other end of the short hose into a container of RV antifreeze. Turn on the pressure washer (momentarily!) until you see the antifreeze coming out of the high-pressure outlet.
• The Siphon Method: Some pressure washers have a siphon hose specifically for drawing in detergent. If yours does, you can use that to suck up the antifreeze. Simply place the siphon hose into a container of RV antifreeze and run the pressure washer until you see the antifreeze flowing through the system.

Important: You only need to run the pressure washer for a few seconds until you see the antifreeze. You're not trying to fill the Grand Canyon with antifreeze, just coat the internal parts.

Step 5: Drain the Pump (Just to Be Sure)

Most pressure washers have a pump drain plug. Consult your manual to find its exact location. Place a container underneath the plug and carefully remove it to drain any remaining water and antifreeze. Once drained, replace the plug securely.

Funny story: Once, I forgot to tighten the drain plug after winterizing, and when I fired up the pressure washer in the spring, it looked like I was trying to create a soapy, antifreeze-fueled geyser. Lesson learned: Double-check everything!

Step 6: Store It Properly (Treat It Like a VIP)

Find a cool, dry place to store your pressure washer. Ideally, a garage or shed is best. Avoid storing it in direct sunlight or extreme temperatures. Think of it like storing fine wine… or a really expensive garden gnome. Protect it from the elements!

Covering it with a tarp or blanket can also help protect it from dust and other debris. Give it a little hug before you leave. It'll appreciate it.

Extra Credit: Maintenance Tips for the Overachievers

Okay, so you've winterized your pressure washer like a pro. But if you really want to go above and beyond, here are a few extra tips:

• Change the Oil: If your pressure washer has an engine (gas-powered models), consider changing the oil before storing it. Fresh oil will help protect the engine from corrosion during the off-season.
• Clean the Nozzles: Use a nozzle cleaning tool (usually a small wire) to clear any debris from the spray nozzles. Clogged nozzles can affect the performance of your pressure washer.
• Inspect the Hoses: Check the hoses for any cracks or damage. Replace them if necessary. A burst hose can ruin your day (and potentially soak you with high-pressure water).

In Conclusion: Happy Winterizing! (And Happy Spraying in the Spring!)

So there you have it! Winterizing your Simpson pressure washer isn't as daunting as it seems. With a little bit of effort and a healthy dose of common sense, you can protect your investment and ensure that it's ready to blast away grime come springtime. Now go forth and conquer, my friends! And remember, a well-winterized pressure washer is a happy pressure washer… and a happy owner!
