Kinetico Carbon replacement frequency and cost
I'm considering a Kinetico 4040 quad system. I saw the system/dealer in a home show. Today I went to their office for some installation questions. Only the tech was there, no sales.
When I asked about the maintenance cost, the tech mentioned that the GAC/carbon media in the tank needs to be replaced every 5 years (depending on the usage of water for sure). At the time of service, they will bring a new tank with new carbon filter to swap with the old one. The cost for that service is about $600.
I'm wondering if the cost is reasonable. I understand that the softener beads can last 20-30 years because they get regenerated constantly. The GAC or carbon, on the other hand, gets used up after a certain amount of water. But the way of exchanging tank is kind of new to me. I see some posts mentioning that the cost of replacing the beads is just around $200. I'm not sure why the cost of replacing carbon is so expensive.
Your input is highly appreciated.
