need help with rverse osmosis system

[mrcopitr]

Hi guys,

just hooked up my reverse osmosis system tonight. It is reef pure 100 gal with di.

I have 40 pds pressure and the system barely produce a slow drip...it does not look like it would produce a 100 gal per day. Is this normal?

Also should the 3 cartridges be full of water at all time, the third compartiment on mine is never full of water....

Please give me your opinion on this

Best regards

Marco
