I just got a second hand rodi system and decided to hook it up based on a few diagrams online of the hookups but I keep having water seal leaks and the pressure gauge isn't working. I know the resin needs to be switched but I wanted to make sure that everything was working like it should before I replaced it. The waste was line is open and water is primarily exiting from this line and a very fast rate, do the hook ups look to be in the right spots or is it completely off?

Can't completely tell from the photos, but it looks like the left chamber is DI resin so that helps.

Order should be:

Right Canister

Middle Canister

Input to the Membrane. Input is at the right side,on the screw cap.

There should be two outputs from the Membrane. The output towards the outside of the chamber is the waste. That should have a flow restrictor on it.

The output towards the center is your RO water. That should go to the left canister, which is the DI resin. The output from that is your DI water.
