I have tried to flush my RO system a few times and what seems to be happening is all the water is emptying from the resin section of the RO unit.
 
When I turn the system back on, the resin dosnt fill up with water and the going out readings go up and up.
 
I then give up and replace the resin which now gives a reading of 0.00 going out which is all good... untill I turn the system off, because of my water butt being full up, and then when I turn it back on my reading shoot up again, and the resin section still dosnt seem to be filling up.

I have had the unit for less than a year.
 
Can I have any help or advice on this please.
 
Thanks
