i unscrewed the switch / lever thing, then pushed some normal size hose over the end of the pipe (you will have a metal ring attached to the end, thats what pushs upto the switch, then i used a jubilee clip to keep the hosepipe on, then put a hoselock connection on the end of the short bit of hosepipe
that hoselock just connects to the pipe for my pole
if any1 needs pics, i can take em tonight
