ro/di running all the time

[mfinn]

Recently my wife mentioned that our water bill had suddenly gone up by 20%, with no rate increase. It has been the same $40 for almost 15 years.
So I checked the usual places around the house for wet spots, found none, so I thought I'd look at the ro/di unit ( BRS) and could hear water running even though it was off. Pulled the waste line out of the washer drain and sure enough there was water coming out at a pretty good rate.
I usually leave the valve on the water supply to the ro/di unit open. It keeps my water top-off container full.
I remember a similar question by someone, but don't remember the answer.
What would be the fix?

Turn off the water supply to the RO/DI or intstall and auto shut off on the containter.

I have a shut-off float valve on my top-off container.
The water isn't going through the ro/di unit.
I've had this ro/di unit for a couple years and this problem has just come up in the last month or so.

Is it possible for those to just go bad?

They can go bad yes.
