Just realized: there is no restrictor on my RODI unit. Consequences?

I bought a used AquaFX RODI a few years ago and have been running it since. It always put out 0 TDS measured water. The pressure gauge never seemed to work though (always 0 PSI)

Recently I've been looking into getting a RO flush kit and couldn't figure out how these things worked.. until I finally read a thread and realized I have no flow restrictor on my waste line. (oops).

So, I guess that means I've been running my RODI in flush mode since day 1.

The question is: how bad was this? The obvious would be maybe I have been wasting a ton of water. Does it also shorten the membrane life?

Anyway.. time to order one now. Oh, the pleasures of buying used

Oops. never mind. Didn't realize the restrictor is inserted into the fitting, so didn't see it

I guess you could manually flush it by just putting a line without a restrictor there

Ya... Some of them are inserted in the exit line, mine is in the John Guest fitting, I must admit I prefer a separate component but I can't give good reason for it.
