BornToHula Posted September 7, 2015 Share Posted September 7, 2015 I have a 5 Stage Bulk Reef Supply RODI System that is rated for 75 Gallons per day. The over the last month or so I have been getting about a 100 to 125 gallons per day flow rate (not that I am complaining!). Is this normal or possibly a sign something is wrong? Still have zero TDS.

FarmerTy Posted September 7, 2015 Share Posted September 7, 2015 What's your TDS going into the membrane and out of it? I have my suspicions you have a membrane that is leaking. In that scenario, you'll still be able to get 0 TDS at the final stage because your DI resin is making up for your leaking membrane. Quote Link to comment Share on other sites More sharing options...
BornToHula Posted September 7, 2015 Author Share Posted September 7, 2015 Going into the DI Resin I'm at 4 TDS. I believe the water passes through the RO membrane and the 3 sediment/carbon filters before it gets to this meter. Quote Link to comment Share on other sites More sharing options...
BornToHula Posted September 7, 2015 Author Share Posted September 7, 2015 I would need to re-plumb some stuff to get a reading directly before and after the RO membrane, but if its unusual to get increased flow I may do this. Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted September 7, 2015 Share Posted September 7, 2015 Nah, at 4 TDS coming out of the membrane, that seems pretty normal. I think you just lucked out sir. Any idea what your water pressure is going into your RO/DI? Quote Link to comment Share on other sites More sharing options...
Bluemoon Posted September 7, 2015 Share Posted September 7, 2015 Nah, at 4 TDS coming out of the membrane, that seems pretty normal. I think you just lucked out sir. Any idea what your water pressure is going into your RO/DI? Agreed. My first thought was a leaky membrane, but it should be higher than 4 if that's the case. Temperature can also affect output! Do you have your system in the garage? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
BornToHula Posted September 8, 2015 Author Share Posted September 8, 2015 Cool, I'm glad its in the normal range. The PSI is at 68-70 going into the system. It's not in the garage, the water comes out at around 76 degrees or so according to my heater. Quote Link to comment Share on other sites More sharing options...
