hi there people i have a brodex system 40/40 ro with water softner and 2, 20 inch pre fillters all fitted up and was working fine but now when i do a back wash that works fine when i spin the numpty thing to start makeing the water nothink comes out now it was really fast now slowed up and now not a drip im lost please help me .
the system is not that old really filters are not even 1 year old the pre filters are still on green and say that they do not need changing system has all ways been back flushed too.
they are the same ones not the 20inch the dial should tell me to change the or do they not really work?
i have taken the pre filters out and started to run and it is still the same it must be the ro but then would it still back wash??
