RO/DI--people who have it can you help me?

[sharuq1]

The tap TDS is about 225 or so I think. The 6ppm is what is coming out of the unit, after the DI and polishing filter thing. Should I take the "polishing filter" off the unit? It is on after the DI, then the DI goes to the storage container dealie. (not sump, this is the container aquasafe sends with their maximus unit for home use).

I haven't checked psi (I don't know how, especially without spraying the house down with water i see no where I can put a psi measurer thingie) , but I really don't think the psi is the problem as I was getting 0 reading before and I am in the city not the country.

I don't know how to backflush the membrane.... If backflushing means turning the wastewater as high as it can go for a few mins then yes I have done that, but it didn't help.

The unit is plumbed into a tap and is turned on or off using the valve that is on the input line. It is not hooked up to a sump or anything like that. The DI does look like it is almost exhausted, but I just don't know why. Should I be turning the wastewater so high that it is a flow and the RO coming out is a mere occasional drip??

It looks just like this unit:
