Its a saturday afternoon mate, some people may not fancy spending all day on an internet forum at the weekend
Have you checked the waste?
Are you getting loads of waste and no pure?
Or are you not getting much of either?
Have you tried adjusting your pure/waste valve?
Does your pump make any differernce at all, or no different to if you weren't using it?
What connector are you using on your outdoor tap to the R.O, and are you actually getting enough water flow through the R.O? (Some of the hozelock type fitting have valves on them that can fail, and not let enough water through)
Unfortunatley, R.O's dont just produce pure, so without knowing what your waste is like, or what difference your pump makes etc...its pretty hard to tell you what might be wrong mate...
