RODI Questions, comments on some odd things with my system

[homebrewdude]

I have a typical reef type RODI system.

75-80psi input pressure
20 TDS before RO
2 TDS after RO
2 TDS after DI

After last filter change, I pinched my waste line closed by accident.
20 TDS before RO
18 TDS after RO (pinched waste)
18 TDS after DI

Not sure my DI canister is doing anything, I have also never noticed a color change in the media.
Is water just swirling around the top and going out? seems odd.

Also I have a flow restricter built into the flush valve.
I have my spigot open to make water, the waste flow is the same with the valve open or closed. I would assume more waste water with valve open??

Any suggestions?

Are you letting it run for 10-15 mins before testing? Are you testing each output state without shutting it off?

Don't tell anybody but I have not changed my pre-filters, resin or membrane in 5+ years... I took the automation (it was fully automated) offline years ago. My handheld TDS meter was eaten alive by its battery.... Who knows what goes into the tank. I don't worry about it.

So...... Last time I changed my filters I must have bent/kinked my discharge line.
So now my TDS is around 2 after RO filter
And I am 1 or 0 after the DI.

I have DI spigot to my laundry sink. I let it run for about 5min. Then I fill my top up water jug.

Thanks for responding to my post!

It was a good excuse for me to order a new membrane and filters. I looked in storage for the automation controller, solenoids and sensors and could not find them. I may just built a whole new controller to autoflush, etc.

What type of controller are you using to automate everything?
