I am treating 6gpg of hardness and 1ppm of iron well water with a Marlo CMP-25 combo filter/softener.
If I configure the unit to regenerate on demand, it would take approx 18 days to consume 2700 gallons @ current household usage (150 gallons per day) to reach the 30,000 grain capacity. That is with the unit configured for 11gpg of hardness (6gpg in water and 5gpg to treat iron). My fear is that 18 days is too long for all of the minerals to be attached to the resin and as a result, I will have to replace the resin prematurely. Although waiting 18 days to regenerate will maximize salt usage, I fear it poses a threat to the performance and longevity of the resin.
Alternatively, if the unit is set to regenerate every 10 days (this is the current setting) then I am not utilizing the full 30,000 grain capacity of the unit. I am also increasing my water and salt usage and waste to my septic.
So how long is too long before regenerating and how should I configure my unit?
