Hiya Stuart.

That is a bit low. You may find that you need to boost the pressure. In fact you probably will. Sorry mate but I wish I could tell you different. It will slow down water production and increase your TDS out a bit. I have marginal pressure at 50 ish PSI and my RO works OK for me bringing my TDS in down from 420 ish to between 5 and 7. Dont panic though it can be fixed easilly and for not a lot of money. I will give you a call on Monday.

Sorry to be a bringer of bad tidings :(

Andrew
