Does anyone know why there is a quick connect on top of the Bug Guy surface cleaner? Is it for ease when you are taking the handle off? I used mine for the first time yesterday and after an hour, I blew apart the O-ring inside the quick connect and water was squirting everywhere at the connection. My brother removed the quick connect and everything seemed to work fine again. I just want to make sure I am not going to ruin the surface cleaner by removing the quci connect. I was running about 3100 psi hot water through it at the time.
