I just purchased an RO
5 stage unit from Bulk Reef Supply. There is nothing in the directions about needing to do anything when it's done running. I'll be using this to fill up buckets for water top off and PWC
but it will sit not running 6 days a week. Is it ok to just let it sit or does it need to be drained in some way?
I'm guessing the flush valve to clean the membranes would be adequate before each use. Just don't want to develop any problems with stagnant water in the unit over time.
Also is there any reason why I couldn't use the waste water for non-aquarium uses such as water for the dogs, garden, etc? The way I understand it, the waste water contains all the solids that's in the tap water, so it's just heavier with those items than straight tap water?
