Hi Guys-
Thanks for the great forum. I have a SQC pro series Reverse Osmosis unit(water factory systems) and I'm having pretty much the same problem that mcgregah is having- replaced filters and the unit was working fine but the flow has decreased dramatically. I have realized it is the the pressure- completely dead but I was able to pump air into the tank with a bicycle pump and the air is staying and bladder is filling. Can I use a regular tire pressure gauge to try and get around 7 Psi? And where should I go from here? I emptied the water out of the tank so the tank is empty . Thanks for any help.
