new 4040 membrane only get dribble coming out the pure outlet. i connected the mains to inlet of pre filters, then into the inlet of 4040 then waste out and pure out. when valve is fully open i have full waste water with good flow. when i close the valve say a quarter turn the pure dribbles out...? any ideas

You need to turn the valve at least half turn to create back pressure. Or you could have inserted your membrane wrong way round. The seal needs to be then end of the inlet.

 
the company i brought it from fitted it. they said they tested it also. i have it strapped to a trolley in a vertical position with the waste and pure outlets at bottom, is this ok or does it need to be waste and pure at top, or not vertical at all.
