Flush valve problem 6 stage Rodi 75gph

[alexmara76]

After 3 months of use of my 75 GPh 6 stage drinking and reef Rodi system I’ve installed a flush valve from BRS .
When I flush the system I should not produce any water , but I produce anyway water and all the TDS crap goes into my drinking water tank or in the DI resin. If I flush or not the system , the quantity of the water I get ,from the blue line it’s alway the same
My psi water pressure is 80 and when I open the flush valve goes down at 65
Plus when I flush the system a noise like leaking air is coming out from the faucet.
Any help is really appreciate,thank you

Here's a good thread which talks about what I believe you're dealing with also.

thank you @MERKEY for your answer, I red that thread ,the problem is I don't get the use of the flush valve if a produce anyway water . What go in the drinking water tank is automatic , so when I use the drinking water it will refill automatically the tank,but with tds crap, TDS goes until 80/100 when it feels the tank, and when I use the flush valve from the blue line comes out
the same amount of water of when the flush valve is closed, also the noise that I comes from the dedicate faucet is like leaking air...something is not workin how it should . I spoke with other guys who use the flush valve and they don't get any water when that use the flush valve
