I filled the res up with water, and turned it on, it emptied half the res, and then stopped, so turned it off. I filled up the res again, and turned it on, and none of the water in the hose circulated.

Yeah it's an OCUK kit. When I phoned them today, I asked if I could just bring the pump back, and he said no, because the order number was for a kit, so an RMA for that order number has to go against the kit as a whole.
When I turn it clockwise to 5, nothing happens. Infact, nothing has happened since I first got it, the pump doesn't get any noisier or quieter from one to five.
It's all boxed up now. I only live 30 mins from the showroom, so I'm driving up in the morning. It's quite handy living in the Midlands. I doubt I will do anything with it tomorrow, not going to touch it till I speak to EK about the block and if that one riser would potentially cause bad contact. It's the one thing making me iffy about putting the loop back together.
