RI/DI problem
 

I just turn on my RO/DI today and notice the water only fill half of the DI Chamber and my TDS meter reading is 0.01

Normally it fill the water all the way in the chamber. I replace the flow restrictor and still samething. Anyone know what causes this?

Thanks

What kind of unit is it? I just fixed a vertex unit the other day, the fittings were loose causing a weird vacuum in the unit. Re sealed the unit's fittings and it fills now.

How long ago did you change the particle filter/s and the carbon?

If your TDS is reading .01 your membrane is shot. Outside of that fact, I am not sure how that relates to your DI only filling half.

Maybe check to see if your waste water volume has greatly increased?

find after changing filters or resin, my DI chamber takes a little time fill completely with water. As for the TDS 0.01? Normally seem given in whole numbers.

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.

I also sense the water flowing into my membrane is on short continuously pulse if i touch it

whats the water pressure like before your RO/DI?

pulsing might be due to the check valve and ASOV
