I already have the oceamo freshwater icp or I would’ve gotten the one you shared. It seems more what I was looking for.The two most common issues with short membrane life are scale (from hardness) and bacterial fouling.They may extend the life of an RO membrane, but do not do anything to extend the DI lifetime.
Before a user should think about reducing concentrate flow, knowledge of the feedwater hardness is a must.
Wouldn't help with... what? Get those lab results and then we can have a meaningful discussion.
