Andy I have heard to discard the first couple of gallons that a new RO/DI unit makes so you should have let it run more than enough in that 2 hours.

50 psi is just a tad below the optimum psi of 60.
Honestly I ran my RO/Di unit for a year on 22psi (yes 22psi) and I just had to change my filters. The low psi meant that it took me 5-6 hours to make 5 gallons. I did just buy a booster pump when I ordered my new filters so my psi is now 60-65 and I can make 5g of RO in just over an hour. The real reason I decided to buy a booster pump was so that I would not waste so much water.
