Has anyone fitted one of these showers? If so did you have any problems connecting the two pipes between the control valve and the shower head? The instructions are that small that Iam unable to see which of the 2 seals supplied fit into the connection at the control valve and the connection at the shower head. I have tried both at each end but the pipe connected to the control valve remains loose even after tightening the nut. To me it looks like one end of one of the pipes should push into the control valve as this already has an o-ring fitted to it however the diameter of the pipe is larger than the opening on the control valve so it is sitting on the top of the thread of the valve connection. One of the seals is a flat rubber washer the other is an o-ring type, I would appreciate any help anyone can offer, cheers
