Easiest Way to Flush an RO Membrane
 

I've heard that just removing the flow restrictor will flush the RO, is this correct. If not how is it done?
One more thing, should I change the DI every time I change the carbon prefilters. My TDS meter is showing .09 and I know I'm up for a carbon change but I'm not sure on the DI.

Yup, remove the restrictor. ANd should flush on a shedual, like once a month.

yes that is how

the aquasafe's just turn a valve 90°.

probably a good idea changing the pre-filters every six month or so along with the DI backed up by a TDS reading

Might want to check that 0.09

Carbon talking the pre or post? Me, I no longer use the post as there for taste and fish aren't complaining.

We sell a flush kit thats under $20 that will act as your flow restrictor and will flush the membrane
