Recently bought a MaxPure 60 RO/DI from Marine Depot. Water production was way more than the manual indicated so I thought something was wrong. In fact, the water produced was almost as much as the waste. Emailed Marine Depot and Robert responded within 24 hours by contacting SpectraPure and then forwarding Scott's response to my questions. While making the adjustment suggested by Scott, one small part fell on the ground and my dog chewed it before I could get it back. Thankfully Scott sent me a replacement part in the mail the same day, free of charge. Good service is hard to find nowadays, so I definitely recommend SpectraPure and Marine Depot.
