Yeah I thought I ha plumbed it wrong, double checked and it's all good. I think the waste solenoid went bad and my check valve/restrictor went out on the product side. The waste solenoid should be in all the time and it's not opening so I bypassed it with a ball valve that's just barely cracked open to create a restriction and I bypassed the check valve as well. TDS is still around 100 before the resin which is way better than the 400-500 it was reading last night. So now I'm making making and wasting water so I'll take that. Going to order a new buddie pump as well. Still have not figured out why it's burning through resin but I'll figure that one out later.
You are just burning through the Anion stage like me? or the cation and mixed beds too?

Just food for thought, I used to buy resins from Amazon and I was using them up quickly, I then bought resins from BRS and they last about 5 times longer. My TDS going into the resins is typically 14-30 depending on what my municipal water TDS is, it fluctuates. I go through anion the most as well. Honestly I haven't measured how much water I can process though an anion cannister before I have to change it, but it's definitely several hundreds of gallons at least.

I use BRS resins. I get around 100-150g of water before I have depleted the Anion resin. Well water is not the same as municipal water. With all the treatments and open to air filtration there would be little co2 left in the water it would have equalized with the air around it. Silicates are still possible but not usually as high. I still believe my issue and @kpreslicka are one of the two. I need to have an icp or other test done on my water out of the ro membrane just not sure what is the best route to go, one day I might get around to it. Currently just got really good at repacking resin canisters. I will also start regenerating resin soon.

Yeah I use the brs ones as well

Just an FYI my TDS out of the faucet was 760
That's not a big deal. This morning mine was 661. I've seen it as high as 1050 and as low as 330 but it always fluctuates, it depends on which wells the city draws from and how they blend it. The well at our new home site is brand new, 650' deep with the water table at about 450'. The water is pumped into two 2500 gallon HDPE reservoirs buried next to the well. The water is still a bit cloudy out of the service tap but the well people say that will clear up when more water is drawn from it. I'm very anxious to find out about the properties of the water, pH, TDS, C02 etc.

I thought it was high until my brother told me his TDS was similar and he lives in town with "treated" water

Okay so I changed all filters and got a new smart buddie pump. Pressure before the membrane is around 80-90 out of the pump. TDS into the resin/out of membrane is 38. So back to the original question does anyone have any ideas on what I could do to lessen the amount of resin I use?

Household & Commercial Water Analysis​

W-5 Household Complete Mineral Test $35.75​

Bicarbonate, Calcium, Carbonate, Chloride, Fluoride, Iron, Magnesium, Nitrate, Potassium, Sodium, Sulfate, Total Hardness (CaCo3), Total Alkalinity (CaCo3), Electrical Conductivity, pH, Est. Total Dissolved Solids, Cation/Anion Balance
For an additional fee, you can order a convenient kit that includes the Household Complete Mineral Test, prepaid postage, a clean sample bottle, and necessary packaging. To order the kit, click here.

Here in Texas, I have my own well at 950’ with a TDS at 1010 ppm. It goes straight into my 25 year mature tank. Because the Edward’s Plateau was an ancient inland sea that was dominated by diatoms, my groundwater is full of silicates, which is convenient as I need silicates for sponges in my systems.

I'm not sure if my depth or the exact things that are in it. I'll have to look into that though thanks

You could run them in series, so you'd be reprocessing the product water from the first membrane through the second one. You'd have a lot of waste water though, but your final product water would probably be just a few TDS or better.

So 38/760 = 5% - so your membrane is rejecting 95% of the feedwater tds. Not great but not horrible. What membrane are you using?

Do you have one membrane or two?

What is your permeate to concentrate ratio?

Is your booster pump before or after your prefilters?

Two membranes plumbed in series, booster pump after pre-filters, and the standard 75gpd ones from brs

Can this be done? Yes. But this is typically not a practical approach with residential scale RODI system.

First, get rid of your second RO membrane.

With your very high TDS I suspect your water hardness is also high. Do you have a water softener?

Then measure your waste water to purified water ratio.

Are you running the system for at least two minutes before measuring your permeate TDS?

Yeah the smart buddie pump auto flushes the membrane and I watch the TDS until it reads 0. Not trying to to be rude or anything but what do I accomplish by taking out the second membrane?
