I recently added a pressure washer back to my set up after many years. Until this afternoon I was disconnecting the hose from my pump set up to the pressure washer. I don't use the pressure washer all the time. Now I have a Y connection so that I can use the regular hose or the pressure washer. I had planned on doing this for a few weeks but today an incident prompted me to get the pieces I needed.
A weekly customer car while vacuuming I found a plastic drink cup. Was going to throw it away but thought they may be saving it for a reason. I didn't want the liquid to spill on the carpet so the straw went in the vacuum and I dumped the little bit of liquid out. Decided to go ahead an rinse it out real quick. I only had the pressure washer hooked up and it was off. I held cup in one hand and pressed trigger with other. WHAM the remaining pressure in the hose shot the cup out my hand. It then slammed into my truck bed and shattered. The cup ended up being trash anyway so no loss. I'll remember next time to depressurize the hose before I use it. Scared the piss out of me though.
