Frequently asked questions
Is Florida water hard?
Most of Florida draws from limestone aquifers, so hardness of 10 to 20 grains per gallon is typical. That is hard to very hard, and it is the main reason Florida water heaters scale up faster than the national average.
How long does water softener installation take?
Half a day of work, 1-3 weeks including permitting. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are grain capacity sized to household hardness and usage; softener only versus softener plus carbon filtration; drain and electrical availability at the install point.
