Hi guys how long should resin last i got a bag of resin from Freedom cause they said it would be cheaper than keep getting the 10" carrtidge of resin when i used to get the carrtidge it used 2 last me about 4 months now doing doing it this way it last about a month any one know why this is happening cheers.
I presume that the resin vessel is after an RO unit as you are in a hard water area.
It's possible that the membranes are becoming less efficient. Have you checked the TDS after the RO? How does it compare with how it used to be.
Certainly if doing like for like, a loose bag of resin should work out much cheaper than sealed resin vessels so your change of vessel may have coincided with membranes getting to the point where they need changing.
