IF I remember correctly you have the Mark 10,000 unit (will treat 10,000 grains of hardness)
So if water source is 10gpg it would treat 1000 gallons before needing regen
With an output of 1.5gpg the softener is still removing minerals.
This is also a brand new unit with first run resin.....not used/regenerated.
Have you tested the hardness of the water source?
I quit even using the test strips after first package ran out.
I could tell my taste/feel when water was no longer 'soft' and would do a regen then.
Ours was an 8000 grain softener and would last about 1 month with 2 adults
How do you like yours?
Is it doing what you thought it would?
Is it time for your medication or mine?
