I have a pressure washer I got for cleaning my kid's dirt bikes. It's 15-degrees here. I used the pressure washer 3 days ago. When I was finished I disconnected the hoses and I drained the water from the house and spray gun. I pulled the starter rope on the engine about 6 to 10 times to get any water in the pump to come out. I DID NOT put antifreeze in the pump. And now I'm worring what do you guys think, am I doomed?? .
