Was at the start of a job so hooked up the whirlaway but could not figure out when I pressed the trigger no water was coming through. Went to change over to the lance to make sure water was getting through the washer ok but could not undo the hose because the line was pressurised. So had another look at the whirlaway thinking the trigger was knackered but seemed to be moving ok. I then looked to see if the jets were ok only to find one of them was blocked with what looked like a broken O ring sticking out of it. Now I was stuffed I thought as could not get any of the hose connections undone due to the line still being under pressure so thought this is a great start to the day. Anyhow to cut a long story short in the end I managed to unscrew the hose connector from the whirlaway but took most of my strength to get that sucker undone. Was a bloody good job it was a karcher screw type hose connection on that end or I would have been well and truly stuffed.
