Adding a DI chamber to an existing household RO unit?

[Triggz]

Thanks for the input. There is a storage tank similar to the one you mentioned installed downstairs. I hooked up the DI chamber upstairs where it is convenient to have a top up/water change reservoir. However, now the DI chamber is plumbed in after the drinking water storage tank. I guess my question about pressure comes back into play. Now I am worried there is too much pressure going through the DI chamber because of the pressured storage tank.

Should I just have them drain the tank before running the DI chamber? It is only a few gallons tops.

Thanks

Not to worry. The pressure after the storage tank is equal to the pressure without the tank. Whether you have a tank or not, the end pressure is the same.
All the DI chambers I have set up are after the tank.
After the tank I put in a tee, one goes to faucet and fridge, the other to the DI
