DI Bypass valve

You are teeing right after the ro membrane the thing playing in sideways in the pic on the clean side (test tds to find clean side). And right before the clean water goes into the di
If the two canisters that are alone are your di you would be splicing into the red line leading to the di
Is the blue line coming from the two canisters the water you use?
Yes @saltkreep88, the blue line is the clean water
So cut into the red leading to the two canisters. Red line piece from three canister side goes into the port opposite of the valve handle. Then left and right from valve go into the di where the red currently goes and one goes to the drain.
Thank you sir, I will work on this tonight and post up a pic @saltkreep88
Marcus, here's a full view shot. The water comes from the RO unit (from the membrane exit) to the valve. Right now the valve is positioned to run the water to waste (I collect my waste water in the 55 gallon drum). Once TDS out of the membrane stabilized (usually around 1 or 2 TDS.....taking about 3 - 5 minutes), I flip the valve 180 degrees, now putting the RO water through the DI canister. Hope this helps.
Yup
So for the first 2-3 mins have the water come out of the red tube before the di
Also your pressure gauge should be moved to after the carbon before the membrane.
Yes the gauge is to see if your sediment filter is clogging and how much pressure the membrane is actually seeing. For placement look at the canister laying sideways over top the three canister, that the ro membrane, you will see one side has 2 tubes and the other side has 1 tube coming out. The gauge should be on the one tube side of the sideways canister.
Turn on the unit and write down the pressure before you move it so you know the original pressure so you can tell if it is dropping
