RI/DI problem

I just recent replace the resin for DI chamber. Mine is aqua fx 4 stages with dual membranes. I just change my membranes last year. The TDS read 183 for in and 0.01 for out

I think you shouldn't worry about it then. The air space will get smaller, untill its gone.

whats the water pressure like before your RO/DI?

pulsing might be due to the check valve and ASOV

0.01 ppm? You're worried about that? I wouldn't be. However, I would be checking TDS after RO membrane before DI resin. When is the last time you changed the DI resin? Did you have the system apart at all or did this problem start on its own? Does it normally drain down in the DI chamber when you shut it off and refill when you initially turn it on or does it always remain full?

I just changed the DI resin like 1 week ago, The problem just start yesterday, before it was find and I flush the membrane for 10 minutes the last time i used which was a week ago

It does normally drain down in the DI chamber half way and then refill when turn it on again.
