Alright, let me tell you about my little water cannon pressure washer project. It all started last weekend when I was staring at my disgustingly dirty patio. You know how it is – algae, grime, the whole shebang. I was about to go buy a pressure washer, but then I thought, "Nah, let's get crafty!"

So, first thing's first, I rummaged through my garage. Found an old water pump from a previous, uh, less successful gardening attempt. It was collecting dust, but seemed to be in decent shape. I plugged it in just to make sure it still worked – and thank goodness, it sputtered to life!

Next, I needed a nozzle. I didn't want some wimpy spray, I wanted a cannon. I found a brass fitting from an old plumbing project. It wasn’t exactly a nozzle, but I figured I could modify it. I grabbed my drill and carefully enlarged the opening to get a nice, focused stream. Safety first, people! Always wear eye protection when drilling.

Then came the fun part – putting it all together. I connected the pump to a length of garden hose. The hose was a bit old and leaky, so I wrapped some Teflon tape around the connections to seal them up. Attached the modified brass fitting to the end of the hose with a clamp. It looked janky, but hey, that's half the fun, right?

Now for the power source. I used an old extension cord to power the pump. Plugged everything in, turned on the water, and flipped the switch. And... nothing. Ugh. The pump was humming, but no water was coming out.

I spent the next hour troubleshooting. Checked all the connections, made sure the pump was primed. Finally, I realized there was a tiny air bubble trapped in the intake hose. Jiggled it around a bit, and whoosh! Water started gushing out!

The pressure wasn’t exactly what you'd get from a commercial pressure washer, but it was surprisingly powerful! I aimed my makeshift water cannon at the patio and started blasting. The grime flew off! It was so satisfying. I worked for a solid afternoon, clearing off all the gunk and grime.

Here’s what I learned:

• Don't underestimate the power of repurposing old stuff.
• Teflon tape is your friend.
• Air bubbles are the enemy.

It's not perfect, but my DIY water cannon pressure washer did the job, and it saved me some money. Plus, it was a fun little project. Next time, I might try to find a way to increase the pressure. Maybe a different pump? Bigger nozzle? The possibilities are endless!

And yes, I got soaked in the process. But that's part of the charm, right?
