Aquasafe - Variable Flow Resistor

[Oscar]

I now have my Aquasafe RO/DI up and running. Just about every connection leaked, mostly because I did not insert the pipe deep enough into the connector. Once I resolved that then no more leaks.

But I am having problems generating waste water. The only way I can seem to do this is to partially open up the "flow restrictor". That device is meant for monthly flushing of the membrane.

If I close the flow restrictor then adjustment the "variable flow resistor" has no effect. I get RO/DI water but no waste water

Any suggestions to get the VFR working?
