[Deleted member 84]

Hey guys im after some advise.

Just bought new membranes (filmtec) ive flushed them for about 5 hours total.

The reading after membranes is 024 ppm. Not really happy wih this to be honest.

The water pressure is 35 psi.

Running 3x 100 gpd filmtec membranes

All pre filters have been changed.

He best reading i seem to get is 018 when on full flush.

Any help much appreciated

35psi is way to low you need 60psi and above, You need a booster pump to increase pressure through the R/O

With 30 PSI I can get 97/98 % rejection rate when testing systems.

Filmtec have a huge problem with fake imitations and if they are cheap they are more than likely not Filmtec.  

Filmtec have tried to rectify this with having a Hologram on the label but you still get copies.
