I can't find anything online that tells me it's not a good idea so any help would b great....
NO!!! You cannot do that!! The RO
membrane is removing solids from your water, so keeping it in a closed loop will plug the system very quickly.... My tap water has a TDS
of 440, and the waste is 550, so everytime the waste would recycle through, that number will get higher & higher with no place for the filtered out material to go.
Fortunately, my RODI
is in my basment mounted on the wall right next to my washing machine.... I just run the waste line into the washer and do a load of work clothes whenever it starts to fill up (You'd be surprised
how much water a washing machine takes to fill!!).
