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
