Simon, would you please see if there is a washer in your drain off cap, I may be able to order one
Tony
Tony I will look for you after the weekend, off out now
but I am sure you could get a rubber washer for it anywhere
Used the backpack for a job this afternoon, put it on my back just to be safe carrying through a house - very uncomfortable, and I should have put some ptfe tape on the hose were it screws in at the bottom of the pack because it leaked all down my backside !
Think its an ok backpack though, will be ditching the straps as I did on my wcw one, but think the lid handle is a bad design, will be getting a trolley for it soon.
Simon
