R/O Water System

[Reef Runner]

I currently am having some problems with my R/O unit.

I have a Microline 435 and it was installed in my house before I bought it. It is only giving me about 1 cup of water before it seems to run out of water. I have heard that it might be the pressure in my tank. Anyone know how I add more pressure of even check it?

Thanks

I have an R/O system made by Premier and had the same problem you are having. My tank has an air pressure valve {just like a bicycle tire} on the bottom of it. I can check it with a tire guage and pump it up with a bicycle pump or any other type of air pump. Hope this helps.

Is the tank heavy? The bladder should have 20lbs or less of pressure since the whole system is pressure based. If you have waste water running constantly but the tank does not fill you could replace the membrane.
